Your "incorrect" examples look better than my typical welds. Oy! Thanks for all the vids. I learn a little from each one.
I have been messing around with flux core for 20 years. I can do a decent job sticking things together. BUT I have never had the slag come off the weld like that. I need to do some more adjusting to get this result. Impressive. Now I need to get out there and make it happen. Well at least try to get there!!
Glad I found this video. I wasted time watching several different videos and you sir just compiled the info of all of those videos into one.
Thank you
One of the best MIG welding tutorials I have seen on YTube. Thanks for the info!
Just finished welding an exhaust pipe to flange. This video really helped me figure out what to look for. I was running too high a wire feed. My first trials were terrible. Almost gave up. This video helped a lot.
My next weld was much better but still not very good. The welder feed was hanging up and poor arc.
I put a new contact tip on and wrapped copper wire around the cheap sheet metal ground clamp. Much better!!
This video made the difference. Thanks!
Great job! Brief, clear, informative, helpful.I am doing FCAW-S for 7 years and, I hope, able to appreciate this video.
I do a lot of flux core wire welding, the video tells you all you need to know. The principles of ALL welding are the same, control the weld puddle. In that respect, it is identical to gas MIG and electrode welding.
Every technique you would use for electrode or MIG welding applies to flux cored wire.
What no one seems to mention is that you need to change wire sizes just as you would change rod sizes electrode welding, although MIG is far more accommodating of wire that is a little too large or small.
Having said that, I use 0.9mm wire for everything form vehicle sheet metal to around 1/4" and the flexibility of the flux cored wire is excellent in this respect.

Very good info, thanks for the input.
I see the light but can't see the puddle. It's like welding looking at a flash light. How do you get past the light to see the puddle?
Barry Wind darken your mask 😉
That was my problem... the mask was too dark. It was so dark I couldn't see the puddle or the metal edge I was trying to weld. I did lighten it and there it was... my first view of a molten puddle. I was afraid to lighten it thinking it would hurt my eyes... but I took a chance. I had it set at 10 which everyone says is the magic number, but not for my helmet.
Barry Wind I stick and mig with my hood set on 9 (Lincoln hood)
An excellent, helpful video. One observation and suggestion: It is well and good to demonstrate "too slow" and "too fast" (etc.), but what about "just right"? I suggest that the short clip around 12:00 be edited into the beginning of the video (as well as at the end) to show what a good weld bead looks like before showing the several possible errors.
most informative and the best instructional video on welding ihave watched so far.
oh my word how satisfying is that final weld (your example of doing it right!) thanks so much for this video. its things like this that make the internet so good! :)
I just went and practiced all the wrong stuff. The only thing I did that you didn't was melting the .030 tip. I hooked up to correct polarity and looked at the box to make sure. Then I looked and read it 2 more times and switched the feeder to positive. Practice was 1/8 x 1 1/4 L, well cleaned. It was horrible and I remembered it doing so well the last time I had it out.
It seems that the machines problem may be my glasses. Thanks for this video, I watch it every time I am outside failing at this.
Farm welding is what my aspiration is.There are a lot of tractors and implements in my world to maintain. Almost not too bad is my self graded work with 1/8" 6011 and 7018 rods on around 80 - 125 AC amps. That machine and my tanks are too much to haul around off the farms. Hence a 110 dc/140 amp inverter MP, two new 20 breakers, 12/3 wire and 20 lbs of FCAW wire. Good thing that's practice wire... lol
Thank you for this well presented and very educational video.
Thank you for your time.
Going to buy the mp210 next week.
Every one of your "Terrible" welds is better than anything I've been able to strike. I didn't splurge for a Lincoln but really, I have addressed all these variables except polarity. I don't think my machine can be changed. Ill look into this.
Just picked up a mig-pak 140. Never tried fcaw before so this is all pretty new to me. On the plus side I'm the only let down in the operation, the welder has fed flawlessly.
Excellent tutorial, without going around the bush but straight to the point...GREAT !! I just bought a BOSSWELD-M100 and with probably an hour worth of practice under my belt..... I can tell you that when I get to achieve your worst, I'll be extremely happy ... how long is it gonna take for me get to that?? hopefully soon enough ....**lol**
Nice very detailed i was wondering about the flux core polarity and you answered it thank you for being specific i am a beginner and was unsure.
When lidl or Aldi gonna stock some more 1mm flux core I ran out 😂😂
Nice and very awesome welding tips,tricks and troubleshoot video..cheers from Malaysia..
Fantastic video, covered everything! Thanks
We can't put a link in the comments but if you go to Lincoln Electric website and in the search bar choose SP-140T the model will come up. Thanks for the post!!
Very helpful, thanks for making this video!
Well done Dan!
This the best flux core video.
This was fantastically informative for me! I'm definitely going to get in some practice tomorrow, maybe tonight if I can squeeze it in. Thanks a million times for this video.
Very informative video. Thanks!
Thank you and thanks again for sharing this video.
Great video. Very helpful!
i second that . you are obviously a true welder . one of the most informative vids i have seen. keep it up.
A good teacher.
thanks for the tips will be giving it a go
thank you very much your explanation is fantastic..
thanks for the video, very informative. Great presentation of the effects of setting up wrong.
Best into jam EVER!
Informative video - Thanks!
I see what i was doing wrong now, this was good information.
I wish we had more experience with FCAW-S wires in our tech-school. We had the opportunity to run it once or twice, but all of our typical FCAW practice and WABO / AWS practice was using FCAW-G
Thank you for the information
This is one of the best info vids that I have viewed so far. It has tied a lot of loose ends as to why I sucked at mig welding. I make great bird poops of my welds. Have been doing everything all wrong. Now I shall go practice and become a good amateur welder.😊Thank you for this video.
That's a cool extract unit you hot there 👍
Good info, thanks!
My Lincoln 180 says 3/8" stick out with flux core, i use nr211 with good results, im going to try it at 1/2" to 5/8" and see how it goes, could that be why it seems a little hot for the settings? thanks good instructions on fcaw.
I found this video VERY helpful, Thank you!
Very good video thank you!
Wow. Thank you for this information you are a great teacher. Wish I had someone like you to teach me to weld
Excellent vid thanks.
great tips thanks for sharing...
Fantastic video! Maybe of you added "flux core" into the title more people could benefit from seeing it though. As a newbie I did not know what FCAW-S stood for and only found this video after clicking on the wrong video, but I'm so glad I did! Thank you.
+killerbanjo Good idea. Thank you. We have added your suggestion to the video title.
+lincolnelectrictv Good stuff, thanks again.
The sheet on my Lincoln door panel is pretty accurate.
Great video
Good Video for trouble shooting for beginners .
Man... every one of those "how not to" welds ,made me think "I wish I could make a bead like that" ...I'm gonna go cry for a bit.
good info, thanks !
Jesus, I suck so bad your worst weld looks better than the best one I have done yet and have ran half of a four inch spool of wire through it.
Join the club... I'm in the same category!
Barry Wind not saying I'm any better but stay with it! Somewhere around 300$ in gas and about 25 or 30 # of flux core in it seemed like something clicked, just started " feeling" it, and suddenly l sucked a lot less!
for me it was a cheap helmet not letting me see what I was doing. I had the mask on a stick helmet that came with the welder. Once I got a decent view of what I was doing and was able to weld with 2 hands I have really come to enjoy welding and found it a very useful skill.
I tried turning the shade down to 10 like one on youtube suggested and it seemed to help. I'm better but not great. I don't know what I would do without the welder now. It has really opened up ways to fix problems that I couldn't have without it. : )
The words from my mouth. :)
Can you please help me. Where can I get the speed and Voltage settings for the NR-211 MP Wire for my Lincoln SpeedTec 200
What is the best set up for using an invectec v275-s for flux core welding?
Fluxcore is extremely underated
Are you doing little circle when welding? I learned how to arc weld I think it's much easier then wire feed
Im havin a issue that my speed seems just right but it sputters like crazy. Like how you showed it with to high of a speed. I have messed with all the speed settings but nothing gets it to do a nice long weld without popping everywhere and leaving big gaps. any ideas?
Thanks!
Thanks for posting this vid. Although informative, I think i would've gotten more out of it, w/longer durations of time of the weld beads being shown, & am in agreeance about showing more puddle closeups, through the welding goggles, along w/multiple situations for each end of the spectrum, for each troubleshooting situations, as "withoutDad" mentioned, and agree w/"Bob Stovall" as well. Thanks again. Aloha
Have a Miller Trailblazer w/dial setting cv do I still have to offset cables?
Thanks a lot :)
Any of those welds look better than what I do!
Barry Wind I usually dip my feed wire 😏
I have thr pro-mig 135 and the chart shows to run the polarity straight for flud core. Is that correct.
Hell I don't weld for a living but I will take any of your welds. Thank good video.
I just saw what I was doing wrong. I am used to TIG welding so I was holding too close and my angle was wrong. Will try again later.
cool video. ive never welded before. not gunna lie it looks insanely hard. i have aspergers/autism and im lookin into the welding program at lccc, local colleg in cheyenne wyoming. does anyone know if welding is a good line of work for people with as
So. This wire suitcase I've been using doesn't have a wire feed speed control. Which is really frustrating. How do I mitigate that? Just up the volts if it's stabbing or globbing?
Hi great vid, but agree about being able to see the puddle and wire, and also the jargon about the polarity, seems you need to be an elecrician too, i purchased a sealey mightymig 100 and apparently there junk but what i could afford without going for used, no ball park settings on the welder and only set up of machine putting wire in and handle on so no help what so ever, wondered if you could help it says the machine comes ready to go so as I've never welded before i wouldn't really know if its the right polarity as my welds would be as bad either way, so could you tell me is there machines like this that can't or shoildnt have the polarity changed, any input would be great, thanks in the uk
I googled for a manual for the MightyMIG 100, but there are perhaps multiple models. The manual I saw for the "No Gas" model said to use flux-core wire (no surprise) and that the torch was connected to positive, which would be wrong, and puzzling since this machine can't handle gas. So could be a mistake in the manual, or actually an incorrect design. At any rate, it's simple to check -- just connect a voltmeter (set to say 200V) with meter negative lead to the ground clamp and the meter positive to the welding wire coming out of the torch. If the meter shows a positive voltage -- the torch is positive, and incorrect for flux-core. Most welders have a way to reverse the polarity, as shown in this video. However the MightyMIG doesn't show a way to do that, and would not need to if it was already wired correctly for flux-core. I suppose there's an outside chance that the Sealey flux-core wire TG100/1 is actually supposed to run on electrode positive. The product page is unhelpful: www.sealey.co.uk/PLPageBuilder.asp?id=20&method=mViewProduct&productid=8473
I’ve tried all your recommendations and yet the gun sputters the wire into clumps. Could it be a faulty wire product?
Fantastico !!
Gonna try some flux core welding with my everlast welder. I need to weld some steel at my friend's house and can't be bothered bringing my large tank.
Excellent vedio
What is the correct polarity for an activ8?
Awesome
ive watched this video 25 times..it it frustrating as hell starting out....gotta keep at it.
Make sure your workpieces are clean... Grinded..free of oil etc....
when do you either straight line drag and push the puddle as compared to washing it side to side and make e, c or I???
+Richard Burdyn Thanks for the question. Sorry for the delay. On heavier material when you are needing a slightly larger weld than you can get with a straight line drag, a weave is fine to do. Some codes do have requirements on weaving and weld sizes made in a single pass so be carefull. Whether you use a C or zig-zag pattern is up to you just be sure you are never pushing the puddle. You risk trapping slag if you do that. Always use a drag technique.
What happens if you welder is not grounded well? How does the welder react?
I am using a pro-core 100 with .030 flux core wire. Is this size wire ok? Or do I need to use the .035 wire instead?
Animal Rammer usually its on .045. but it just depends on your job honestly
When I make welds at school in manufacturing Tech 1, I don't get the ripple effects but my instructor says it's fine. How, do I get more of a ripple effect on the weld?
Move your hand in small oscilation. Back and forth. See czcams.com/video/FEJDqJrZyOQ/video.html
very thorough video, i just bought a Miller 211 and am learning to weld with flux core .030 wire. im noticing that my spatter is 10x worse then anything im seeing here. my welder has an auto feed setting where you just choose material and wire, and the machine does the rest, i tend to think its accurate based on reviews and my own experimenting with manual settings.
Check your polarity. If not, test drive a Lincoln and see if your problem is just the welder itself.
Your 211 will make a very nice bead using FCMA but polarity needs to be changed on the machine from electrode positive to electrode negative, you will notice the difference in s lot nicer weld with less splatter
Any videos you guys make on trouble shooting on pipe welding, fill and cap
+Tallon Conwell Tallon, we will do our best to get something for you.
can you put a link for the welder
I would like if I can try this because my videos on CZcams Rudy does plumbing comes from my experience through the plumbers assc
can u weld stainless with that setup, no gas?
how about a tutorial on the c300 machine I have one at work I know their capable of so much but I have no clue how to bring its potential out lol I use it mainly for mig ...would much apreciate it
Thanks for your interest. As of now, we don't have a c300 video on the horizon but we will add it to the list.
With my budget, only weldet I can afford is the Harbor Freight 90amp flux core welder. It has only 2 voltage settings but variable wire feed settings. How do you trouble shoot those welds with limited voltage settings?
Good luck, that thing uses AC so all the welds look terrible.
depending what you're welding, I would set the welder up in the lowest setting. you don't want to burn through your material. if the weld is cold, either make another pass, on low setting, or go to the high setting.
I never weld on a bench where I can hold the tip perfect.
I'm always on the ground reaching around something and barely fit the tip to the weld.
No crap man! All these how to videos show a pro welding in optimal conditions. Anybody with half a brain can pull that off.
Paul M indeed, gravity is not your friend... since you mention it I don't think that I've seen a single vertical or inverted (upside down) weld in any of these videos. I hate overhead welding, the hot stuff always finds a way inside of your leathers...
@@aadoublea - you need to learn how to weld properly under ideal conditions before you can get good results when you're out of position. Must master the basics first.
i am a coded mig welder and have about 15 years of stick experience. i am curious to see how this wire welds in my hands... maybe one day..
would have been nice to see the puddle guess i expected more from lincioln i can pro tig and hold my own stick welding but never flux welded before the way i see it its just stick welding with a really skinny constant feed stick i wonder if like stick wire some don't spatter as much as others or is the flux selection very limited
+Kilian John My thought exactly!!! I took welders training over 30 years ago, and THEY HAD VIDEO WITH A FILTER THAT ALLOWED YOU TO SEE THE WELDING PROCESS!!! Without it, this is far less useful, and A WASTE OF TIME to watch the actual welding - you might have well just cut immediately to the result, since watching a bright arc for any time at all serves no purpose!!! Pretty sad for a company like Lincoln, you'd think they'd know better.
+Russell Russell Thanks for your feedback. Other than the lack of puddle video, what other suggestions do you have for an informative video? Most other comments suggest that this video was quite helpful but we'd like to get better. Your suggestions will be welcomed and appreciated.
I concur with what he said. I took training with the military and their videos SHOW exactly what is happening in the puddle, after all THAT is what is important from a visual aid. I don't care how much others find this helpful, if you aren't going to be able to actually see what's happening then you might as well leave out simply watching a bright light, it's just not useful. That you don't know this is rather strange in my opinion.
@@lincolnelectrictv I think this was good, and covered a lot of ground. I've watched it several times when I need a review. I would have liked better "Arc Shots", but realize this is not easy. I was glad to find you're using the popular wire I just bought, more or less guessing. It was very good to have one at the end that put everything together.
@@russellrussell3190 I don't think that's entirely true, because we're talking about gross faults, where the sound and light changes in a big way. Sometimes you can hear someone making a mess of this from across the room. So this is good information too. I would sure like to see "helmet cam" footage with it too.
Is flux core good for joining galvanized to stainless 10ga thick
I think brazing is what you need here.
I watched your video. Very informative. I still suck so bad. I have cheap harbor freight Auto darkening helmet. I can't see my puddle very well.
All right, i need to go check the polarity on my machine. Maybe its right-maybe wrong. And I've been using it the way it came for years...eash.
Do you suggest running without a cup as shown in the later parts of the video?
yes no need for a nozzle
This is innershield. No cup is used because there's no gas.
But is it better?
I have a Lincoln 125. Great machine for my needs. Excellent video. I feel like I need to go check my machine for the correct polarity after watching this given how sloppy some of my welds are. Ha! Just for clarification, using a self-shielding flux core wire, the feeder wire needs to be on the negative? I believe that's what you said in the video.
..self-shielding, wire negative...... gas-shielded flux core,wire positive......
What is innershield NR 211 MP ?
Great job, I noticed you said you wanted to feedback to improve. Try a video with 2 variables gone wrong instead of one, like too high voltage with perfect, short, and long stickout. Then do too low of a voltage with the same stickout criteria. Plus, use pictures in your videos that you pause on, showing side by side comparisons of labeling the two variables conditions for what you chose in for each variable. And last show in that image the perfect conditions. Hope this helps you and if want to send me a free welder or welding equipment for this quality feedback let me know.
It's probably common to have two or three things wrong at once! Might make for a long video if you tried to work all the changes! (say, wire speed LOW, and travel HIGH, then wire speed HIGH and travel LOW). That's a great suggestion, but it might take a series of videos to implement. Ah, sometimes people who weld for a living are not good at diagnosing things and changing the setup, I think in factories there's someone who sets everything up for everyone? I have got paid a few times to just look over something and see why it isn't working, or maybe even talk about it on the phone! You wouldn't believe it, but people do things like getting the wrong gas bottle, and everything goes to hell and they just can't imagine WHY. I know people right now who "welded" for years with the wrong polarity, and it was nothing BUT spatter and slag! You could pull welded steel stuff apart with your hands! SO, common scenario: Wrong polarity, way high travel speed, AND many starts and stops, so that a lot of "weld" is trying to deposit on to SLAG! (Engineering students are doing this) I sometimes pull off an allegedly welded thing with my hand, and yell "Either I'm SUPERMAN, or something is WRONG HERE!". I'm not actually any good at welding, but I can watch CZcams videos, read old books and yell. It's something!
I got lots of practice to do.
Should do a video on 5/64 232/233 or nr 311 for column spliced 3 inches thick
...yeah, that's the kind of stuff you find on off-shore oil rigs....
I was an offshore welder and never heard of that.
@Frank deluca true.
Lincolnelectrictv PLEASE give Jody a call. I'm amazed that this is the best you can do with your arc shots. Call him he does a great job of letting you see the weld in process. It would help me greatly to see the manipulation of the arc. And please let us see the slag coating before you remove it. The color, shape and coverage all will help us.
Thank you DanO
