Hi, thanks for the video. This explains it. I appreciate you getting down to business and me not having to skip through 20 minute tour of your garage, house and details about all your pets and gadgets and tools.

After all these years, still the best explanation of why we weld electrode negative with flux core welders.

You have just saved me chucking away my MIG .. I have always used shielding gas and yesterday I tried flux core, it was a disaster! Exactly like your first demo.. thank goodness I now know why .. very clear advice.. thanks a lot!!

I got a flux-core welder as a gift a couple years ago and was  very disappointed with the amount of splatter.  After viewing this video I reversed the polarity and was very happy with the results.  Reversing was not easy.  I had to un-crimp the leads and re-crimp, but it was well worth the effort.  I had given up using this welder because of the splatter, but now I can weld the thin stock that had been so difficult with a stick.
Thanks for a clear explanation with a great demo.

You have just solved 99% of my problems. Thanks brother!

Bloody hell! Here I am struggling to learn to have better welds and always made a mess with splatter everywhere. Struggled to find the right setting so there were minimal splatter. Sometimes it’s either too high and would burn the wire to the tip or burn a hole.

I never even researched or read anything about the polarity change. I just assumed that all mig welders had the same polarity with a gas setup. I am just learning to weld and I need a ton of practice.

But I’m sure after knowing that gas and gas less setup have different polarity, I’ll be more determined to give it another go. It was discouraging when I look at my crappy weld, it’s one of the worst anyone would ever see! Not having the right setup doesn’t help either.

THANK YOU for the video!

I want to start using flux core with my everlast welder. Thank you for the very clear explanation on everything.

This is the best video I've seen on this subject. Thank you!

Mystery solved. Clear, concise, to the point. Bless and save ya.

Thanks for taking the time and effort to show this and explain the polarity adjustment in the comment discussions below.

good point. us rookies need pointers like this from time to time. I'm gonna change mine now
thanks

Recently posted a video on modifying my Flux Core welder and didn't have an explanation for why your ground clamp should be DC positive, but now I do. Cheers m8

Thanks a lot for the explanatory and practical presentation because it helped me a lot. I'm an amateur and I usually do welding only as needed to fix something or make a little thing I can't buy. After changing the polarity, welding goes much better and looks much nicer. Thanks again! God bless you!

[minouchat]

Nothing better than a video to see the comparison ! Thanks. Have a nice day !

[patiencepeeler]

Thank you for the tip I'm a new hobby welder and this really helped answer my problem with my little 110vlt flux core welds spatter

[jimc]

Excellent explanation and video on polarity, clear, simply and right to the point.

Good video, l just bought a flux core 130A set brand new £80, after only ever using stick, arc, MMA welders since early 80s as l was a coded welder, but this set really is OK, 0.8 wire, get very good welds, but for the people buying for car body work your better with a gas mig set as these flux cored will blow holes in the plate, but for general welding there great.

[criticalreasoning]

Wow, great demostration! Thank you sir. I just wish you had mentioned to use knurled wire drive wheels with soft crush-able flux core wire. When changing from gas to gasless you need to change the drive wheel and the polarity. Flux core needs Negative Electrode and Knurled Drive Wheel.

probably the most useful video ever for home welders THANK
