Ok I have literally been watching welding videos all day. Like all freaking day. This guy is literally the best because he gets to the point and knows what hes talking about. Anyone who welds would benefit from this video as a reminder of what not to forget. Very straight forward video and to the point. This guy is a real pro!
Thank you very much for straight forward info and tips. All the best mate
Love it subscribed you remind me of my grandfather when he would teach me. If CZcams was alive when he was younger this would be it. Thank you
That Everlast welder would make a great Christmas present for my nephew!
Hope he enjoyed it!!
Thanks! Iv just got my new gasless welder and this has helped me heaps!
I really love this welder I bought mine 2 years ago and it's still going strong
It's a good little welder. If you go fluxcore it is very portable.
G'day Paul. I'm trying to weld thin sheet with flux cored wire using a Misho 220 mig/mma/tig inverter welder. I had been fiddling with wire speed and amps for the best part of a day trying to get it to weld without spluttering or blowing holes. I have also watch so many youtube videos trying to get my head around it I was going mad. Until I watch this video, nothing was making sense. So mate, thanks very much and now I'm going back out to the shed and changing the polarity.
Thanks for this video. I've never tried welding flux core with my everlast.
This guy is the best. He is an open book and seems to tell you everything he knows. Great guy. Thank you, sir.
Thanks for explaining the drive roller knurling.
I see from some of the comments there is some confusion on polarity and I think it comes from the terminologies used in welding.
Most mig and multi-process welders I have seen are setup from the factory for mig wire polarity and have the "+" and "-" symbols and terminals located on the inside of the unit above or near the wire feed mechanism. The default from factory the mig gun is connected to the (DC +) positive screw terminal. To change the polarity of the MIG torch, loosen the screws as in the video, remove the cable and install it on the other terminal.
Polarity for a MIG gun using solid (MIG) wire, or gas-shielded flux-cored, or metal-cored electrodes is (DC +) positive (DCEP) with the work clamp serving as the (-) negative output terminal. This is known as reverse polarity.
Self shielded flux core wire is the opposite polarity of solid (MIG wire) and so the Mig gun polarity must be changed to (DC -) negative which is DCEN or “straight” polarity. This is accomplished by changing the wire above the feeder from the positive terminal to the negative terminal (so the wire feeder is negative) as in the video and connecting the work clamp the (+) positive output terminal (usually on the front) of the machine.
Always be sure to verify wire manufacturer's direction for polarity recommendation for any specific wire.
A common flux core self shielded wire found at big box stores and places like Tractor Supply is Hobart Fabshield 21B (E71T-11) and the recommended polarity is DCEN. Lincoln Innershield is another common self shielded flux core wire found and it also uses DCEN
The drive rolls for Everlast are marked with the grove size like .030" (0.8mm) and .035" (0.9mm) marked on each side of the roll where that size groove resides. Make sure the roll is not installed backwards on the feeder for the size wire being used or it won't feed correctly or will crush the wire.
Many thanks on the reverse polarity explanation. I haven't welded since high school, and that has been about 30 years ago..lol so again thank you.
Thank You, Sir !
That was SUPER !
Thank you,, a straight to the point video on setup.. cheers
Thank you for that simply explained effective video it was very helpful
Thank you Sir great video great information wishing you could keep uploading more mig welding videos and info on how to weld with bigger metal and thicker mig wire
No one ever mentioned about the knurled drive nut for flux core. Thanks
Best video on setting up I have see top marks 👍👍
Good video. Im a beginner and learned a couple things from your video. Thx!!!
Excellent video. Great teaching skills.
Great video, didn't know I needed to do this after buying a used Lincoln Mig.
love this video!!! best teacher for DIY guys like me. god bless him.
Excellent tutorial, thanks!
Try using a pair of electrical cutter/strippers for cutting the cored wire. It puts a clean cut on the end and you dont have to fight putting the tip on.
Thank you so much for making this video it was great help to me & very easy to follow

Great video. I really like your presentation style. Thanks.
I would have liked some talk about settings on the machine though. I'll check your other vids for further information.
Thank you so much for a great explanation. Wish I'd have watched this before spending all kinds of money and time trying to convert to fluxcore without really knowing what I was doing. Da....
Here in December 2020 and just wanted to say thank you Sir
Thank you very much for the quick response. On a scale of 1 thru 10 what would you give the Everlast 140e
Thanks. You helped me a lot.
Awesome video very informative, thanks.
Great teacher! Thanks
What a great video. Thanks.
Nice job, thanks for the info
Nice compact welder. Flux core is perfect for making this a portable welder especially if welding out where there might be a breeze. Thank you for the video.
Perfect welder for portable use.
Is that welder currently available for sale?
Yes. It is called the ESAB Rebel 215ic. Do a Google search and you will find many sellers.
How does it compare with the everlast mig welders?
Thank you dady for excellent explanation Anumbuaseh Humphrey from Cameroon
great demo
Thank you for your video. I just bought a mig welder and was doing some spot welds and I was getting to much splatter. With your video, I see I was using the flux wire and the polarity was reversed.
One thing he did not mention is that not all machines can switch. The very cheap flux core machines save money by not including a gas solenoid. On the back of the machine where the power inlet cord goes in there should also be a brass fitting for a shielding gas hose, if there's no fitting with a plastic dust cap, you do not have the option in the future of going to solid wire MIG. Something to think about.
Hi, great video. I'm an old dodger and only worked with oxy/acet set ups, this is really new to me and am excited to start. But I'm working outside and flux core is my only choice. The pieces I have to weld can't move so I'm wondering if an extension cord can be used? If so would a heavy duty extension cord work? Thanks Mike.
thanks again great video
very very helpful thanks weld.com
Thank you sir!
Thank you for the info
Excellent thanks
Great presentation :) What about the wire tension?
Just found MIG Monday.....watched one episode and immediately subscribed! I just bought a 110-volt flux core welder [Forney FC-I model] for hobby welding and home repairs if necessary. I am sure that being a "newbee" I'm going to learn a lot! PS....your opinion on my choice of welder ? Thanks!
Hello dear
Learning a lot from your videos 👍
Was wondering about the flux core wire roller K groove versus the V groove ones ... What difference would it make if i use the V groove for flux core welding ? Will it affect the quality of the welds in any way ?
Thanks a lot and keep it up !
Thx... Cause i wanted this for Flux Core...
Great video very well explained, I never owned a MIG welder or any other welding machines. I know nothing about welding, I find it to be a useful tool to have in my garage. I want to be able to weld small metal things, it's a hobby of mine making small tools for the garage I really don't want any gas bottles around .what machine would you suggest for someone like me who has no idea of welding. well not yet anyway. any suggestions will be most welcome. thank you in advance. subscribed
Thank you very much but you forged to explain about the tension of the spring where the wire goes
There is no spring on my mug welder where the wire feed goes through . It’s plastic,but is it possible to add a spring or is it unnecessary?thank you for any help
Im building a homemade bicycle and only welded once with flux core. what settings should i use for the .035-.050 wall thickness
I really liked this video. Thanks for the presentation!
Timely video? Planning to weld outside. Can you recommend a safe working environment for welding outside (minimum square foot workspace, distance from structure (like a house), etc.? Thanks Ace
Awesome vids mate, so if i set my mig up like this with flux core wire i can weld my galvanized trailer?
Yup, I recommend using a flap disk on a grinder to remove the gal from the joins you're gonna weld though (for weld quality) and certainly do it with lots of fresh air. Welded gal is nasty fume stuff. Source below.

That little everlast welder sure would be good to have as a portable flux core welder. Gosh welders have gotten smaller.
Thanks for the informative video. 1 question, on the drive shaft you have a knob that tightens the wire, it has numbers written on it (marked from 1 to 5, revealed with every turn). What do they represent or how do they relate to the system.
Wire tension. I believe most manufacturers recommend around 3.5 for a setting. Little late but hope it helps.
If you are switching the DC plus and minus how does this effect the wire speed motor controller? My motor controller runs of the DC being fed to the wire. There is a circuit board with an SCR TYN 610. Will let you know if this causes a problem. Otherwise all good!
With a MIG/flux core welder would stick be the best option for aluminium if your welder can do it?
great sir
thanks
Did the 200E come with the flux cord drive role ?
25 yrs ago I found you can weld galvanised steel by obviously grinding most of the galvanising out and increasing your wire speed by approx 10-20%. Whether it's possible with synergic sets I'm unaware?
Is Everlast a good product in ypur opinion?
Where do I purchase the 0.9 knurled drive roller shown in this video? The only one I could get from Everlast was the 1.0/1.2 size roller. Thanks!
Found one here: www.ebay.com/itm/172160785481
So what if you still are using gas can the flux core wire be used like regular wire?
hello i bought a gasless welder, do you think the polarity is already correct?
Most likely it should already be set up on
Electrode negative
Where can I find the roller at?
You are good ,i watched others they sting.
this dud is cool
Which welder would you prefer? The Longevity Mig 140 or Everlast 140e? Thank you
we've never tested the Longevity, but have used the Everlast with success many times.
I would definitely go with the Everlast.
I'm only used the flux core. Just got a bottle of stargon So I'm going to do this in reverse.
Many thanks for your knowledge. Using metric now (uuuugggghhhh) I see many flux-cored wires in as 0.9mm. Rarely do I see 0.9mm knurled rollers. I see 0.8mm/1.0mm K rollers - which roller groove should one use? The smaller 0.8mm or the larger 1.0mm (for 0.9mm cored wire)? Along same line, there are no 0.9mm tips that I can see, so I presume use a 1.0mm tip (size larger than the wire itself in this particular case)?
.9mm is.035 inches.
.8mm is .030 inches. 1mm is .040 inches. I hope this helps.
I'm 69 yrs. I live in a motorhome so I will weld outside most of the time. I'm new to welding, So. will flux be the best for me?
Seems like flux-core welding going to be the best for you. Besides, living in a motorhome you don't have a lot of extra space for the gas tank needed for MIG welding.
Or stick
Great vid.. just subscribed 👌🏻... questions|
Where are you located?
Would you be able to give me a week "crash course, hands on" type? I would pay for it.
How much is the unit used on this video? Is there a similar unit at a cheaper price in Harborfreight or Northern Tools?
God bless & Tks again 🙏🏻👌🏻👌🏻👌🏻
I thought it was well explained, just would have liked better visual of the welds. Thanks
Can't you just swap the leads on the front if you're welder has detachable leads?
So flux core ='s: negative to the metal clamp and positive to the wire.
And mig ='s: positive to the metal clamp and negative to the wire.
Is this correct?
will this not give you a shock,i will need to change my one round i just need to make sure i don't get a shock
whats the difference between welding flux core with gas and without gas? ive seen people use a flux cored wire but also use shielding gas, but I thought flux core welding was made to be used without gas? I thought the shielding gas was for only solid wire?
+David Santa Cruz "Usually" when using a gas with flux-coerd wire it is because the core is made up mostly of chemicals designed to match base metal in chemistry and/or strength so there is not much room for deoxidizers and/or shielding so the gas becomes necessary to protect the molten pool.
+Weld.com thank you for clearing that up for me
Thanks for trying......poor camera angles and blocked views inhibited me from getting any real value fm the video. Thanks for the information and helping me understand though.....
Isn't it way easier to just switch the leads externally?
I would have thought, a "How to Set Up your MIG Welder for Flux Cored Welding" video would have talked about settings with voltage and wire speed. Could you please direct me to a video that goes over these settings? Thank you.
its a gasless mig welder by the way, sorry
You talk very confusing going back and forth on certain things. And dont sound very convinced even though maybe you are
You are not so informative....!!!! You didn't explain how to adjust the tension on the spool bad bad bad
11:20 Its a Teflon liner, not sure about a nylon liner...
