Gasless Mig Welder, Part 2. Mig welding and gasless mig welders, part 2.
www.learn-how-to-weld.com Gasless mig welder, Part 2. Part 2 of this gasless mig welder video I show you the inside of the mig welding machine where the drive rolls are, where the mig wire goes and also talk about changing the polarity of the machine for welding with gasless mig wire or solid mig wire.

Cheers mate
top video dude..

Should we go out an get a patent for the product and market it ourselves? I did get your other comment the you deleted just above this one. And I did too see/read an article about what you mentioned, I can remember what grade of wire it was though.
@learnhowtoweld Thanks for the reply. I could list a dozen serious weld quality reasons why not to use self-shielded FC wires. As far as the welding outdoors in breezy conditions issue, I believe Lincoln just developed a hi-tech new device it calls “a cut-in-half cardboard box” which, when combined with the well known “duct tape” process, makes drafts a non-issue for MIG welding outdoors. (mild sarcasm…… As IF Lincoln would ever spill the beans on THAT little trick of the trade…)
@learnhowtoweld Seriously, paying 50-100% more for consumables in order to make welds which there should be every reason to doubt as to their quality…all because you can’t afford a decent wind screen? That seems truly crazy to me.
It’s my understanding that self-shielded wires have been implicated in a number of serious earthquake failures in California, as the welds produced by the same typically lack fracture toughness.
This is all just my personal opinion though.

Yes the gasless mig wire is more expensive, no doubt about that.
There is nothing wrong with this wire though. It can produce welds as strong as normal mig wire with gas. I have people who use this stuff at home for DIY, for on site structural welding and full time in the workshop welding where they use this all the time as opposed to ER70S-6.
What the issue is I think is that people who don’t know how to weld get hold of this and make bad welds, and give it a bad name…….
A 50 lb spool of “self-shielded” flux core wire typically costs $85-$150 U.S. or more. A spool of low cost ER70s-3 is about a third of that. A bottle of Argon+17%CO2 costs about $30. Just take a look at any of the truly scary welds produced by that “self-shielded” garbage, and you would have to be insane to allow this stuff in your welding shop.
