Finally! A weld review where someone can actually weld! Nice job sir!
Thank you Mark. Cheers J
What an amazing concept right? Half of the videos are the blind leading the blind.
Seriously as soon as I watch a review on a machine and the guy is like I don’t know or I have never welded before I click off lmfao what’s the point ? Waste of time even making the video , come back in two years, make a video once you know and have really put the machine to use. Seriously I’m appalled by all the reviews from people that are cluelessly leading people
Great job Thanks
Being involved in mechanics all my life I’ve always thought buying good (expensive) tools was the best way and it is on the ones that are normally used very hard. Learning that sometimes the less expensive tools are a much better value is a hard lesson to learn and still after all these years it’s nice to get someone else reminding me of that, thanks again. It’s funny but in gifted enough hands a silk purse can be made out of a sows ear :)
I bought a Telwin transformer mig in 1993. Putting the cost into an inflation calculator it would be 2500 today. The current equivalent is about 1300. I bought a similar machine from static arc that does gas, gasless, lift tig and stick. Modern inverter migs are incredible value. My transformer mig is so robust I suspect my grandchildren (don't have any yet) will still be using it when they are my age.
Really impressed with the review and your honest feedback on the machine. Ultimately, I guess that you get what you pay for. I usually review a product thoroughly before I purchase anything and I haven't been put off the ROHR welder. Thank you.
Best review I've ever seen, covers everything, nice and clear.. thanks!
Thank you so much. Cheers J
nice to see someone take apart a machine while reviewing and looking under the hood. Very helpful in not only helping newbies like me decide what to buy but also learnt some technical knowledge too in how to even check if a welding machine is of good build quality!
Thank you so much. Cheers J
Now that's what I call a review. Thank you. Great welding skills too!
Thank you. Cheers J
Hi Joshua, I've really enjoyed your video, I'm thinking of getting into some "hobbyist" type welding, with a machine like this, so this review has been really helpful - many thanks! For interest, in the UK our electricity supply is considered 230v nominal, we agreed to harmonization in 1993, it has always surprised me how that seemed to go unnoticed by many people here, I guess because it makes very little real world difference. Thanks again and keep making these great videos!!
Thank you John. For hobbyist type work I would recommend a basic stick welder as the welds will be stronger, no need for renting gas bottles, basic power supply can be used and they are far cheaper. All the very best. Cheers J
Its refreshing to have a UK review for kit available to the UK, 90% of the reviews on You-tube seem to focus on the US market. I was considering one of these sets, but due to no-one production a review (until now) I opted for an old Migatronic for £100 that does the job.
Were you able to obtain gas through work - I ended up getting a hobby weld bottle for about £120
Keep up the excellent reviews, looking forward to the MMA / TIG one
All the very best
Dave
Hi Dave. I use a cellar gas company, they take deposits only so no rental. I have a small mixed gas and a large pure argon. The deposit is refunded when you return the bottle. I paid £80 for the large bottle and £20 for the small
Dave
I have to say I was in the same boat 🤣.
90% of the reviews on her are American biased especially for beginners trying to get reasonably priced non branded.
Appreciated the review for us hobby welders.
Looks pretty serviceable if you’ve got a half decent understanding of buck converters/switched mode supplies, and op amps.
If I get one, I’ll definitely insulate the panel and check the caps aren’t touching the heatsinks like you mentioned! A few degrees difference in temp can make a huge difference to a capacitors lifespan!
I’m torn between this and a gys easymig 150!
Thanks for this review, i have been considering this set, for my car restoration
Simply great video. Only just came across your channel in the last few days and I've been playing catch-up with your material. You've inspired me to take up welding again - and maybe a bit of hobby smithing. Your video on side-port forge made me want to build one - so of course thinking what model/brand welder to start with to build that.... this video definitely helps with that! Please please keep making this kind of content!
Thank you Ashley. I will. Cheers J
I have the same model in Australia, for outside gas-less Mig welding, [just delete the shroud then is like welding with a pencil] it never misses a beat,
gas-less wire is great nowadays and we are too lazy to drag around the gas.
Has welded 3 steel Ute trays, and 3 sets of ladder racks, lots of job-site welding, even a temp onsite drilling rig, 6mm is about the max though. My guys love it, and borrow it for side jobs all the time. 3 years old , paid for itself many many times over.
Great to hear that it has the potential to last a good while under high stress work loads. I agree 6mm is about the max for the MIG function, can do the rest with the MMA if needed. Cheers J
Wonderful review, had to sub.right now
What’s great about your review is the sense that you want to genuinely help the buyer to get the right welder for them.
Great Video
That's very kind of you, thank you. I've got a follow up video coming. I'll use flux core, stainless steel wire and the stick welding function in that one. Cheers J
Can’t wait
This video is perfect. Your welding skills and explination was brilliant. Hell your voice was perfect well spoken, didn't drone on and I understood everything. I don't think the screen wording did though.. But now back to the welder I've ordered one of ebay for £219 free delivery. I repair accident damaged cars and alike, so for me this is a perfect buy.. I will Will be watching more reviews of yours. Thank you
Thank you Craig very kind. All the very best. Cheers J
I recently purchased a Sungoldpower 200 amp welder from Amazon. To me all the cheap Chinese 200's look very similar and looks like the same mig torches, some are longer than others and some give you more consumables. I was hoping I could weld 5/16" plate with one pass but, I will see. This is my first welder and haven't welded much at all in nearly 20 years. Very detailed review. Thanks much
All those brands are probably all made in the same factory. Thank you and all the very best. Cheers J
Excellent review - very interesting - thanks Joshua, best wishes for 2020.
Thank you have great one. Catch up again soon. J
Hi Josh. Fantastic review that was clear and informative. No Bull just fact in a very chilled style. I'll be check out your other videos. Thanks
Thank you Rob. Cheers J
Just bought this welder never used one before so this was a great video! Cheers
Thank you. I recommend the channel weldingtipsandtricks.com it's great.
Well done. Great genuine review. Thank you
Looks like I've found my first MIG welder to learn on. (Let's not talk about the stick welder I bought that was far far too powerful for my thin van metals! It's not been out of its box for 2 years).
Great vid very helpful
Thank you. All the very best. Cheers J
New to welding. Immensely helpful. Many thanks Joshua.
Thank you Peter. Cheers J
Really good review. Went Into everything in-depth and more. Wish there were more like this. Only thing is would have like to have seen how it performed with the stick wealding function
Thank you so much. I'm going to do a follow up video on its stick welding function and flux core, stainless and possibly aluminium spool gun too. When I get the time... Cheers J
I bought one MI250. The first thing I did was replace ALL the screws with Stainless ones. It's so easy to get good quality welds even on thin metal.
I think that warning panel translates to "Do NOT lick the welding nozzle whilst the trigger is pulled".
Very professional review: thanks for your time and efforts. I've been looking at these guys, and this helps. Was excellent you took it apart. It would be nice to evaluate the duty cycle. Maybe best way is not to use it to weld, but get a constant load, and experiment with that.
But that's quite a load: 200 amps @ 12V (?): 2.4kW.
You can buy an off-the-shelf unit to act as a load, but if you got some Kanthal wire, and adjusted the wire diamter and length to keep it within its constant resistance/temperature band, that would work.
Thank you. I've yet to get an isolated breaker for it so I haven't used it as much as I would have liked to. I'm upgrading my workshop to account for a plasma table and will upgrade my power unit also. I've got lots of sculpture patterns I want to build with this machine and so I'll do a follow up video at some point. Cheers J
@@joshuadelisle OK, well, I'm pretty sure i'm getting one, so if I figure out a good way to optimise it, I'll pass it on.
Am looking at your other videos: very nice.
Brilliant review josh literally just brought one from watching this Thanks pal
Well done. Thank you. All the very best. Cheers J
Your a good instructor for a begineer, thanks! Time to buy a mig welder.
Thank you. All the best. Cheers J
Got one. For hobbyist work it's fantastic. I only use flux cored .08 which makes it very cheap to run, and as long as you have good extraction, it's great.
Well done. Cheers J
Excellent. I admire you for the thoroughness. Best wishes
Thank you. Cheers J
Amazing video thank you so much im looking to buy one and your very profesional review made me believe that its the machine i need to rebuild my beetle and w123 merc thank you
I'll be ordering one in the next hour. Thank you!
Nice one! Cheers J
great review will help a lot for purchase of a suitable machine for one of the old blokes in the shed.That need to do a bit of ever thing well done .
wow what a great vid, im on the fence about buying this machine, and came across this review, its true if your using this machine for industry you wouldnt be buying this machine, but you pay for the build quality. im a part time welder and want to replace my heavy mig welder , so glad you opened it up and looked at the moss fets and the capacitors being close to the heat sinks, etc, but if you know what the parts are you can get them , but im not that savy, so if anything goes you cant get hold of anybody or a diagram to name whats what, this is the problem with cheap stuff , it eventualy dies and thrown into land fill or sold on for parts or not working
Great review! Looking at buying this exact one.
Thank you so much! I've got some exciting projects lined up for this welder, some that I'm sure you've never seen before. All the very best, cheers J
Great review Joshua thanks. Any chance you could post more videos please with the welder in use. Love to see a professional put it through its paces. Your video has inspired me to get the same model.
Cheers
Thank you so much. I will when I get a project worthy to give it a good go with. I've not used it much but got it in preparation for lots of sculptures all to come. Cheers J
Lovely review buddy, the warning label says if you have the machine plugged in and switched on, when you open the side door use gloves because of the live exposed terminals inside, my dyslexia is pretty good lol
I had a good trawl through Amazon when I was looking for a mid range MIG machine earlier this year and in the end it was the lack of aftermarket and decent English in the literature that put me off buying one Joshua. I've heard from others that if a no brand machine doesn't suffer from immediate infant death (ie straight out of the box) then it should last out the guarantee at least. In the end though I went for a Clarke from Machine Mart on one of their VAT free offers. Fairly cheap and has performed well so far, plus there's a door to go knocking on if anything goes tits up and Clarke have their own service numbers to call for spares etc.
Considering Amazon have their own guarantees though for a home shop it's worth taking a punt on.
BTW as a result of your welding helmet review (and my buying one on the back of it) I'd like to return the favour and say if you're after a cheap decent apron check out the Leaseek one from Amazon I did a review on. Bargain at £24, seriously.
My first welder was a second hand Clarke stick 140amp. Brilliant bit of kit still going strong for a friend 12 years on. Looked in the catalogue recently and it's only £100.... I forgot to mention how MMA and Tig are just a transformer and are so cheap compared to MIG, because of the moving parts of MIG is where cheap isn't good. Like though with this one that I can upgrade and customise all the parts. Will check out the apron. Happy new year. Cheers J
@@joshuadelisle Same to you fella, hope 2020 is a great year for you, the biz and the channel.
If I was a bit better with the old eclectic trickery I'd be happier rummaging around in the guts of those things and fixing stuff myself but as things stand once the magic smoke escapes out of them I'm at a distinct disadvantage. I can't fix that with a hammer :)
very informative and great advice cheers fella
Thank you. Cheers J
anyone else hoping for a welding lesson video ^^ ?? those weld's look 12/10
I brought this very machine a few months ago. As a total amateur I have found it to be very good. My only downside is there is no instruction grid to help me find the right settings. As you seam to know what you are doing (unlike me!!) it would be fantastically useful if you could do a video on settings using this machine. I tend to use it for thin automotive sheet metal on co2.. But a second video on this machine would be ace!!
Sure I'll do that. I've been asked to do the flux core settings and stick welding demo too. Thank you and all the very best. Cheers J
@@joshuadelislethx for this review ! I was planning to buy the 250Aa model (for 20€ différence....) and as a beginner I would be interested also buy a setting video !
@@sylvaingenevay3147 thank you! I did think to get the 250 too but I know my power supply won't handle it maxed out and I only need it for the low settings. For any frequent serious MIG welding I would get a second hand 3 phase machines from a good brand. But I would need an industrial unit to use it...
@@sylvaingenevay3147 I bought the 250 model and it came with the mig gun and the ark torch with stamings in them labelled to only 200A so tbh it's only worth getting if your going to replace the Gun and Torch for One rated to withstand 250A & Also with a Circuit breaker or something, because as Josh said it will just blow a fuse
where did you bring it from
Thank you for the video!
Fantastic review
Thank you Gary
Good way to look at a purchase. Thanks for the info.... Don't know about the bribe for a good review. Seems like that would blow any credibility with Röhr.
Yes that the first thing I got out the box and was instantly worried.... Happy new year catch up with more in 2020. Cheers J
What my welder came with is 2 twenty amo fuses that I replaced for the 13 amp on the 3pin plug and so it draws roughly 16amps from the wall. I've never had any problems with welding it on high heat.
hi josh. i cant remember where i saw it but i remember in one of your videos, you showed the separate spool holder you built for your welder so you could take the 15kg spools. could you do a detailed vid on that?
cheers Simon
Good god. Just got my welder and my welds look like road kill. Mad max style.
Ha ha. Keep practicing, try lots of different settings. weldingtipsandtricks.com I'd a great channel to learn from. Cheers J
Super review, some real good food for thought from this man and its hugely appreciated. Happy New Year to you Josh and your family. Keep up the great work! Best of luck!
Thank you buddy. You too have a great 2020!
@@joshuadelisle You're very welcome!! Really looking forward getting in touch and we'll get some dxf files moving. That welder looks ideal for the artist blacksmith, 3mm type material where penetration is not that important. Seems ideal, no gas required!! Good night & thanks again my good man!!!
I used a mixed gas with it but I think it will take a flux core with the appropriate roller. I like that you can use stick on it so if you need a good strong weld it has the amps to burn a 7018 @3.2mm. between both my machines I have the holy trinity stick, Tig and MIG. I just want a pulse AC/DC Tig and then I'm a complete man.... Cheers J
I must say, even Rohr's hundred quid MIG welders are pretty good, managed to weld up two rusty Transits with one, and no hiccups. The only issue I had with it being a transformer rather than inverter was that you couldn't fine tune the voltage so it was either barely any penetration vs burn right through when working with sheet metal. The Chinglish bit was hilarious by the way XD
Good vid there. Stumbled into here as I'm bit curios to possibly buy Timco branded TIG and noticed from video title that Timco and Röhr machines are quite likely same exact models. They seem to be ok choices for hobbyists. I have Fronius TIG at work, but no way I'm going to spend that much for home use 😀
Thank you. I got the Rohr 250amp AC/DC TIG for very little money and does just fine. The cheap machines work but may not last under industrial conditions. I consider them as disposable (recyclable) for jobs and they have earned their keep quickly. I've not had ob break that I couldn't fix either yet. Cheers J
Great video man
Thank you!
Excellent review, and sound judgement calls. Thankyou. Graham (Industrial Electrician. NZ)
Thank you Graham. Cheers J
What a great review
Thank you. Cheers J
A machine that's capable of securing 8mm mild steel for that price tag is pretty impressive. This welder could easily be used in many applications of metals and jobs. Impressed 👍 also for £20 quid extra can get the 250 fi model
It WILL do 8mm very competently. I've pushed the 250 I have to 10mm in a V groove butt joint and the penetration is impressive
Lovely welds Joshua.....
Thank you. Cheers J
I bought the 250amp machine then spent a few hundred £££ having a 16 amp circuit with round connector installed just to run it. This will happily weld now without constantly popping fuses or overheating any house wiring.
ALWAYS wear gloves with these IGBT welders as they have direct (albeit by transistors) and if a failure occurs, you WILL get hurt.
Helpful, thanks!
Thank you for watching! J
I had a similar welder to this, around £400 - it did the job, but after I switched to a high-range welder, the difference was like night and day.
Many of the new high-end welders come with a bunch of features that makes welding much easier.
That's true. Nothing beats it. Those smart pre sets and wave control is handy. However do I like honing the skill of understanding the settings and manually perfecting the bead profile. I feel it makes me a better welder.
Great review.
Thank you
Interesting video! I like how you explain the reasoning of buying a cheap unit and double-checking the interior for faults!
What type of filter did you put onto your camera before you started welding? Is it a IR filter?
Thank you. I used an N1000. Cheers J
I wouldn't put a blanket on the circuit board to insulate it from the casing. I'd glue or affix, in some way, several strategically placed plastic or rubber standoffs to the case to prevent the random vibrations or possible dent forces from causing contact with the circuit board. The blanket may cause overheating and lessen the duty cycle.
Ah when I said sheet I meant a Flatt board of plastic. Like sheet steel but plastic sheet. Not fabric
Interesting video, thanks. When you weld the T you use an interesting torch angle. Sort of pushing the weld forwards rather than dragging. Different than a lot of videos teach. Is that to get better penetration in the thick steel? Regarding your mains current issues, a 13A plug fuse will pass quite a lot more than 13A for a bit. As much as 20A. You’re dissipating more than 1W in the plug though (that’s the design limit for a UK plug) and it’ll start to get hot. From my old knowledge of MIG with transformer type machines you can only really weld about 130A continuously on a 13A plug with a standard fuse. Some people advocate using ‘illegal’ 20A fuses to get a bit more. If the plug doesn’t get too hot (keep checking) I wouldn’t worry about doing that too much. If you say your breaker tends to go working at 150A then I reckon you have a 16A breaker on the circuit to your workshop. Probably a 2.5mm square SWA or twin and earth. If it’s SWA cable right back to the breaker at the consumer unit, it wouldn’t sweat 20A so you could get yourself a bit more headroom. If you’re nervous, go for a B trip curve rather than C. It’ll go quicker.
Thank you. I now have it on a 32amp plug and breaker and wires to match so no worries there. Yes the push method is industrial standard but also better for watching the puddle and so you get better consistency in my opinion. Cheers J
@@joshuadelisle - That’s ideal. You’d easily get a whole 250A off that I reckon. Maybe more!
Brilliant.... at last we have an end users honest review. Based on this review I am going to order this machine as it seems absolutely spot on for 3mm mig which is about the max I would use it for. Just need to find a reasonable gas supplier in South Yorkshire for a domestic client, cheers buddy 👍👍👍
I'm pleased with it. Thank you. I recommend a cellar gas company that do deposits instead of rental. Cheers J
Mig( metal inert gas)
Mag(metal active gas)😁
An English welding vid bloody hell.
I have subscribed so you can run but not hide.
I have the same exact machine. Ordered it last christmas. I went to use it the other day and it turned on but just wouldn't weld. I contacted the company i had it from on ebay. And i sent it to them via an overnight courier. They sorted the machine out straight away as it was still under warranty. Union mart i think they are in the uk. If it of any interest.
That's good to know. Cheers J
Almost went for one of those machines myself, but in the end I opted for a Powermat from Poland as it had a spool gun socket. So far I've only tested it with stick electrodes as I'm skint after xmas and can't afford any of the gas/regulators/wire for MIG yet. :-/ Still, the results with basic stick welding were leaps & bounds beyond my first beginner attempts with a cheap Aldi buzz box.
Mine was probably made by the exact same factory. It has quite few external components in common with yours. I've not opened mine up though.
I've not tried the stick with mine yet until I fit a new plug on it. The cheap stick welders are great as long as you can get the full 140amps out of it otherwise it's no good. This mig isn't up to welding anything above 8mm but with a 3.2 7018 electrode you can do any thickness with 140-200amps and simply stack the beads on anything over 15mm thick. All the very best. J
@@joshuadelisle yeah I've put a 32A plug on mine right from the outset. Probably only needs a 16a but I didn't have any spare ones to hand. Mine came with a Euro style plug and a pathetically cheap UK adaptor that I'd be wary using with a hair dryer never mind a welder! Mine will just be used for pretty typical weekend warrior fab work when I can kit it out properly.
@@philanaemic nice one. Same really. As and when I get a new unit doing my stuff more full time will I upgrade to industrial kit. I would probably go second hand also as I know where to get spare parts if there is ever a fault and still have a quality machine built to last.
Sir, you are a master; thanks for the demonstration - I have a similar TIG machine from Rohr with a fiddly barb gas connection in the back. In your video, I saw that you have got ridden of that. Please let me know what connection parts and hose you used to replace that nasty barb connection? many thanks
Thank you so much. It's still a barb but I put an adapter on it for a push in pneumatic fitting which I use for quick changing on all my machines. All the very best. Cheers J
As about as good a review video you could hope for. Excellent work. I'm looking to start welding mainly 25mm mild steel tubes. Would this be a good machine to start with?
It depends on what your building. This is good for general thin material. If you want strong pipe work for like roll cages I recommend a TIG welder. Otherwise for structural welds I recommend a stick welder. Cheers J
I bought a 140 amp Miller transformer mig for £400 back in 98 when Italians were making miller's low end models.. They had them on special cos nobody trusted Italian transformers would last back then so I took the gamble 😂😂. Still going strong 22 years later . Never had anything go on it since I replaced gas solenoid with heavy duty one @Couple of years in . . It pops 13 amp fuses in 0.8 at 140 amps 😂😂🤷.. Also melted Those skinny torch ends when I got anywhere near its 60% duty cycle 🙈.. No mosfets to pop... my rtech tig and plasma have both been back to Gloucester for repairs in last ten years.. Excellent customer service but yeah.. Thier not as bullet proof as even a low end Italian model 😂😂😂😉
Great video, much more informative than most. I'm guessing this is the same machine sold by Rallydesigns in the UK as the Blackline MIG 200?
I'm planning to buy one, and that machine gets a lot of 5-star reviews, but I'm a bit wary now hearing that buyers are offered a £10 rebate in exchange for a good review.... (if RD / Blackline offer the same rebate)
Thanks
The rebate thing is common with Chinese stuff and I ignore it. Yeh they are all likely made in the same factory as all the interior parts are very much identical. So far she's working well and I'll use it to make a stag sculpture next. Cheers J
@@joshuadelisle The interesting thing with the blackline model comes with 32 amp plug which was why i was interested in the Rohr model as it had 13amp plug but maybe i can get away with a 13amp plug on the blackline machine as i dont use it full power ? very good review
the external power output is for a spot light etc. and the button inside the wire door is for feeding wire through to the torch.
Great video Joshua, good depth and tear down of the internals, Not sure if anybody else has asked this question. Can you confirm this machine is both gas and gasless?
I just spoke to a seller on eBay and they are under the impression it only works with gas? Many thanks for the upload!
Hi. Thank you. I've baught some flux core to try it out but not had an opportunity yet. I believe you can because you can reverse the polarity.
Dohhh! Just noticed the one I've been trying to buy is the "MIG 200 Fi" the welder you have reviewed the "MIG 200 Mi". The search continues.
Many thanks bud.
I like this review - what voltage and wire size were you using when you hit spray transfer on the 8mm?
It was nearly maxed out on 0.8 wire. Not enough wire feed for 0.6. cheers J
Hi Joshua, Great vid, thanks!! really good to get a UK (rather than all the US) based video and opinion - like some of your other subscribers I'd love to know more about this machine - settings, wire, (flux cored wire?) wire feed speed, gas?/gasless? and info on what type of regulator and gas bottle info - if you can :) I am buying one this weekend and as a novice any help would be greatly appreciated
Thank you Peter. I'll do my best to do a follow up video soon. I've got another power hammer upgrade, more tooling on nail making in 10sec, a stag sculpture video and few other projects popping up. I would like to do another horse head video using all 3 common welding methods as well as flux core. Until then I fully recommend the channel weldingtipsandtricks.com .Cheers J
That warning label has to be the best example of Chinglish I have ever seen. 😄🤣
Brilliant video thank you 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Thank you for watching. Cheers J
Thanks for the (comprehensive and interesting) review. I've recently purchased the same model (with the intention of using it to - hopefully - learn how to weld). However a technical question which I'm sure you could answer for me. The operating manual (p. 4 & 5) shows the set-up for gas & gasless MIG welding. For gas welding the link cable terminal and positive terminals are linked, with the work earthing cable going to the negative terminal... Whereas for gasless the link cable terminal and negative terminals are linked with the work earthing cable going to the positive terminal. In other words, with gas welding negative earthing to work - with gasless welding positive earthing to work (an earthing polarity change) - is this right? I ask as the operation manual, p.4 MIG welding instruction 6, goes on to state: "Connect the earth clamp to the negative terminal...", etc., which can't be done if the gasless setup instruction is followed. Now to (again?) expose my complete welding ignorance: If the only difference between gas and gasless welding is that gasless wire produces its own gas-shield, why would the terminal connections for gas/gasless need to be different?
Sorted... The Operating Manual for gasless (flux core wire) welding is correct, i.e., "for gasless the link cable terminal and negative terminals are linked with the work earthing cable going to the positive terminal"... As the electron flow is from the negative electrode (flux cored wire) to the positively earthed work - it reduces weld-spatter. This is due to the hottest part of the arc in the positive earth configuration being at the work surface. I'm never happy until I know why!
Thanks for the video. Alas, I just checked Amazon and the Röhr MIG-200MI is not listed for sale here in the US. Could be because we use 110VAC in most household situations. 220/240 VAC is far less common.
Yes I tried to find a link for you but they are only available in the UK. 110v is less common here and requires a transformer to use one. Cheers J

@@migavia Thanks for the tip. As near as I can tell, that site only offers the Röhr MIG-200MI welder in multiples, i.e., minimum order of 5 units. The price is amazing, however.
@@idahobob173 Minimum order is just formal,you can order one unite,I have contacted them before.
@@idahobob173 you can also check alibaba's sister site, aliexpress.com They cater to individuals much more, while Ali is more geared for business to business transactions.
120v is the US standard, but most welding machines and welders use 240v when possible since it's impractical to get enough power from a standard 120v outlet. 120v machines exist, and they work fine within their limitations, but they are rather limited both in duty cycle and current output. If you can't add a 240v outlet to your house, you might be able to use either a dryer or stove outlet and run an extension cord to your welding location. It's not very practical in a lot of ways, but it's something to consider. Best of luck with your research!
Excellent review Joshua. I've been looking at these but have also found one on eBay (Blackline MIG-200) which appears to be the same machine with different branding, it's being sold by user rallye-design with a 12 month guarantee (est.1972) and it's even £65 cheaper. Have you come across this one at all?
Great video, very informative and useful, thanks! I've been looking at this welder for myself and spotted there is a 250A version of the same for only £20 more, can't immediately see a downside, did you happen to look at that too? Many thanks.
I did see that one, I didn't go for it because I knew my electric board will only take 150amps before I blow fuses and trip switches. I would also be interested if they put a faster wire feed as when I put mine on max the wire feed isn't enough to cope. I may even upgrade my motor to a higher rates version if I can. Cheers J
@@joshuadelisle Have you tried with 1.0mm wire at the top end? There is a table in the manual which shows both versions and they appear to be the same for everything apart from input and output ratings.
@@rhysmowen I haven't, mainly because it only comes with a 0.8 & 0.6 roller die and I've not got a roll of 1mm wire. I would assume the 250amp would handle 1mm fine.
Hi Josh, Brilliant vid and so off the back of watching this on Sunday, I ordered one on Monday & it turned up next day 'today'!! . I also order Amazon's gasless mild steel flux cored 0.8mm spool. Question I have is Josh, can I use this with the 0.8mm feed roll that comes with the machine as standard, or do I really, really need to get hold of a toothed or nurled feed roller?? Thanks for replying and advising, cheers Gaz.
Well, bit the bullet and just ordered AMALL1524 from Amazon for £11.99 incl delivery. It's described as 'CHNsalescom 0.8-1.0 Kunrled-Groove Mig Welder Wire Feed Drive Roller Roll .030"-.040"'.
www.amazon.co.uk/gp/product/B07BDK7WTM/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1
The only thing is it carries a 7 to 8 week delivery from China via Chnsalescom.
Hey Gary. Fantastic well done on your new toy. Knurled is better but don't use solid wire in knurled roles because they wear out and stop gripping the wire. I've got my self a spool of flux core also to do a video. Just been using stainless wire with argon. Cheers J
@@joshuadelisle Thanks for your reply Josh, It'll be really interesting to see your next vid MIG welding using the flux core wire and to see how you set up the MIG 200MI unit.
I'm interested to see what dial settings you use on the unit and what results you achieve with it.
On my new unit, I've just replaced the supplied 2m black power cable & UK 13amp plug for a 10m 16amp cable with a new 16amp round connector, so I can connect up at my garage 16amp outlet and use the welder at the end of my drive.
I've additionally made up a short 1m converter cable using a 16amp socket to a 13amp plug to enable me to use this welder at my sons house who's only got 13amp sockets, but will obviously have to watch the power levels, so we don't blow too many fuses.
Looking forwards to your next related videos.
Thr sticker means: pull plug before opening the case, or else ... (Cat could die) You have to feel the meaning.
nice vid ,r tech for fill all of your concerns
Agree
I can't believe how good this review is. New subscriber.
What is it with the Chinese? Would it really cost them so much to get a proper translation?
Thank you. Got more coming soon. Cheers J
Hi Josh, have you had any issue with gas usage on your machine? I seem to go through a 110L disposable bottle in a matter or 40 inches of weld? Any recommendations for pipework etc for rigging up a proper bottle or any advice how to diagnose and rectify leaks?
Hi Alan. You can check for leaks using a spray bottle and a mix of water and washing up liquid. Basically you spay it on the joints and if bubbles appear then you found your leak. Open the bottle all the way when in use because there is a rubber seal inside that it sits in so it doesn't partially leak while using, turn off when not in use so no leaks happen through the night. The correct pressure can vari and not be accurate on regulators, there is information on line to what the pressure should be but my method is to wet the back of my hand and test the gas flow by just feeling the coldness of the gas, you can also turn it right down and do tests runs increasing the gas until perosity stops occuring that way you'll optimise gas efficientcy. Maybe I'll add that to the follow up video. Cheers J
very German sounding
but Chinese .. but at the price ,,,
at a sixth the price of ewm or fronius you really cant complain , again , if you had to throw away six of them before your into the price of a top brand machine , as long as you dont need the last twenty percent of features your winning hands down.
a very fair review and a lot of good points made.
ah and a ps ,,, the outlet is probably for a water cooler , granted not on this model , but on the tig maybe or on bigger things probably one case pressing does a few models.
That's a good observation regarding a water cooler! I like that it is cheap enough to modify and customise to my own spec and that all the leads and tourch can be upgraded. It's Dutch apparently but who knows, might not be available after Brexit..... Happy new year. J
designed in Germany , built in china ,
but lots of named welders are built there so are everlast and low price esab and lincoln i think.
It's not Mechanical inert gas but Metal Inert Gas except when using carbon dioxide or gas mixes that contain CO2 or oxygen and then its Metal Active Gas or MAG for short. The thing with these cheap units is back up, before I retired I used big Migatronic welders (350 amp), on one occasion the electronics board went bang when I turned it on first thing in the morning when the machine was about four years old, I rang Miganglia and they came out that morning and replaced the board, it's service like that you are paying for. After I retired I purchased a cheap chinese mig welder that went bang at when turned on after 13 months of very little use to get it repaired was going to cost so much that I went out and purchased a little 200 amp Lincoln made in Poland all chinese components inside but the quality of build was so much better than the Chinese manufactured unit and it only cost £350. The ability to switch polarity is not just for SMMA it also allows for using self shielding flux cored wire.
There rotary Polisher looks good
Most early cheap mig welders had quite high voltage ranges; SIP130 22v to 28v. This was ok for thicker materials but not for car welding. I'd like to know if the voltage range on this set could start at about 14 volts. This would enable a good dip transfer on say 0.6 mm wire.
The 10 in 1 welder I reviewed recently has excellent settings that would enable those parameters. Cheers J
Hi Josh good review. I’m sure when you were talking about fitting wire in the machine you were saying about having a bigger roll of wire and running it from outside. How would you do this as it’s a great idea 15kg of wire works out much cheaper than 5kg. I was thinking of making a trolley with some sort of drum holder behind the welder. But don’t know how to get it to the feed without having lots of lose wire. Any suggestions would be very much appreciated. Thanks.
Hi Russ. Thank you. Exactly that, I would either make or convert a cable/hose reel frame to hold the larger spool. It will need tension so it doesn't uncoil like you say, that can be done with a large washer, spring and nilock nut so you can adjust the tension that it doesn't free spin but can still move with a pull from the welder rollers. Cheers J
Joshua De Lisle haven’t built it yet but l am getting all the bit together so it’s ready. I bought a pipe with an 8mm ex dia and a wire liner. The liner fits in the pipe almost perfect. So I will drill through the back of the case run the pipe as close to the rollers as possible and back to the new drum holder with something holding it all up. Not got to that bit yet. This is all assuming I can weld good enough to put it all together.
Or just make a re-spooling jig similar to what this guy has done. czcams.com/video/qLC8-Svq7yk/video.html
The Ebay listing for this states that the input (mains) current draw is up to 28 Amps, so yeah a 13 Amp plug is insufficient. I wonder if the cable itself is sufficient?
We've got 16 Amp hook ups here (with breakers) so I guess I'll change the plug, that should be sufficient for doing 4mm?
Nice demo with the acid - I'm a noob so I'm definitely going to be applying that technique to check my practice pieces. Looks like I could learn a lot from this channel.
Thank you Dave. I've actually had an electrician come a wire up my new workshop and fitted 32amp plugs to all my machines now. I've used this a ton just, I built 40 of 3m frames made from 3mm thick angle iron and it did great. I do recommend the 250amp if you can as this has its limitations and had it on full power constantly even on 3mm thick.
that extra plug in the back is for Co2 heater for MAG welding
big names big bills
Well wear! Looks a lot better quality than my SIP Mini Mig. Do you have a vid with details about your Tig?
I can do if you like. Got a torch upgrade video nearly finished on it, I'll add a bit more detail of the machine if you like. Cheers J
@@joshuadelisle if you can squeeze in a few details that'd be great! I have a big old Miller Dialarc but like the portability and efficiency of the inverter machines. I saw your stove video the other day too, what a great design! Nice to see good ideas coming to life, well done.
@@swordofthelord7104 thank you I will. I have a 220amp oil filled arc welder similar if not identical to an Oxford. It weighs so much it needs steel wheels to move it about. It's my favourite welder but my little inverter is so small, light and easy to use with hot start that I've never needed my old one for anything. As and when I get a new shop the old girl will be back burning and earning....
@@joshuadelisle I look forward to seeing that in the future. All the best for 2020!
great review! Just ordered one there, have you tried MMA on this welder yet? If MIG maxes out at about 6mm how thick can you weld with MMA
Thank you. I haven't yet because I use my TIG with the MMA function just because it's already set up. I'm going to do a follow up video and test out the flux core settings and stainless steel welding as well as the MMA function. My Tig is rated the same 200amps so I can weld any thickness with up to a 4mm electrode. Cheers J
@@joshuadelisle thanks for coming back yes that would be a great video! In this review you looked at all the parts that could give issues and the ability to replace them with easily available after market parts, it would make a great video to go through common faults on these and what the culprit parts might be and how to identify them (would be especially interested in this as I now own one)
@@howyegettinon thank you. Sounds like a good idea. Cheers J
I think whoever wrote that dangerous warning label on the side of the welder has dyslexia! Lmao 😂
Would you recommend trying their tig welder after using the mig?
Can only be better than my Tig, so sure I reckon they would be fine. I want to get their AC/DC 250 version with pulse and HF start. That would be my choice. Cheers J
Excellent video and review. You really know your stuff. I was wondering if you could help me. I've just got my hands on a Rohr mig 200FI. It all powers up ok, but it isn't producing any amps. The machine is new. Do you think it could be an easy fix? Thanks in advance for any help you or your viewer's could give me.
If it’s new ask for a replacement unit or a refund! Attempting to repair it yourself will only void your statutory right to make them replace it!
I agree with Johnathan. I'd send it back as faulty, get a refund and re order. Cheers J
Exelent review, thanks Joshua.
Currently a new model has been released 250 MI but looks exacly the same, maybe a bit more powerfull.
Joshua please tell me, that welder will be good for car body repair ( sheet 0.5-1.0 mm thick) or too strong? On the MIG min power Is only 50 amps
It will be plenty. I got the lesser model because I don't need it for large work but wanted it to have a very low minimum setting for very thin and fine work. Was worried the more powerful model would struggle on the low settings. I'm doing lots of thin sheet with it so needed more speed than Tig to be more efficient. For structural work I use stick and use 7018 electrodes for serious stuff. Wouldn't use MIG thanless it was better, I would get a second hand 3phase industrial machine for anything thicker than 6mm mild steel otherwise. But I like it it's a good machine.
Many thanks for your response. I know tig is a more precise but I don't have experience. I would like use mixed gas mig and .6 wire.
Could you recommend any good inverter/ mig machine with low power for car body welding, please?
Thanks
Damian.
@@musclecapri this one is fine but the 250 model may not be. 0.6 is what I use. Different mix gasses can effect the penetration. I use H4. Cheers J
Hi Joshua, its been a while since this review. I did miss if you gave an overall worth it or not? Understanding there are trade offs. For me this would be a learn to weld and light use really. Thoughts?
Hi. It's still going well. Used it for a large job recently making lots of frames. I recommend the higher amp version as it's not penetrating as much as I prefer on thicker stock. I use a 12% mix gas. Must use a 32amp plug, 6mm or above cable and correct breaker if you do go for one. For learning to weld I recommend a simple stick welder rather than MIG. They are cheaper and don't require gas rental. All the very best. Cheers J
