For gmaw (mig) I've always used .023. Not cause it's best, but because thats what was in the 1st. mig machine I ever ran. (Old Solar 2160) Liked the "MIG" so much I bought one and ran .023 for years on EVERYTHING that I didn't weld with a stick, or tig. Finding the "sweet-spot" between wire speed & heat was the key up to all the machine will do.

Oct 27, 2007 · I am trying to weld 22 gage sheet metal with a Hobart 140. I am using Argon CO2 with solid .030 wire. It keep burning through and making big holes. I have turned the the amp down and the wire up. Nothing seem to be working. Suggestion welcome. I am new at this!!!!!

weldingsupply.com is the best price that I have ever found on the Esab Easy-grind wire,in both .023 and .030 sizes and the silicon bronze wire,also.I actually buy all of my wire and most of my supplies from them.Thier shipping cost is quite low also.Here is a link.You will have to scroll down the page quite a ways.I have introduced several boby shops in my area to this wire and …

Jun 22, 2005 · I normally turn the shop fans away from me when welding and run 22- 24 most of the time. Last edited by Roospike ; 06-22-2005, 12:30 PM . Millermatic 210 "Big Blue"

Oct 21, 2006 · The other version asks that one punchs a 10 mm (3/8") hole on the top metal sheet. Which one is correct? 3. Names: Is Mig Plug Weld the same as Spot MIG weld? 4. Voltage setting: The instructions says that one has to use a specific voltage setting when welding a specific metal tickness.

I've read that works for welding shut drilled holes. I have no experience with mig other than reading various forums. I've done some gas welding with varing degrees of success. I've soldered all my life. Gas would make a mess of the sheet metal flatness, probably worse than the mig will.

Nov 22, 2004 · MIG welding 2 different thicknesses 11-22-2004, 09:12 PM I was hoping to get some tips or techniques on MIG welding metals of different thicknesses together.Like welding 1/8 plate to car sheet metal (ya know very Monster Garage-esque).What do …

Braze flux is corrosive ( that is how it cleans the metal ) , if any flux is left over the metal will rust. Add in a torch flame oxidizes the metal a bit and you have every reason why MIG is so much better on automotive sheetmetal. Brazing is good for small areas that need "glued " together to reduce the chances of cracking.

Apr 21, 2017 · The sheet metal I was welding I coated with Aluminized Bloxide Weldable Primer (see picture). I was using 80/20 gas with Lincoln .023 solid wire and no matter what setting I had the welder on, it would not stick. I even turned the welder up way past the recommended setting for the thickness of sheet metal I'm welding and it still won't stick.

Feb 14, 2004 · A gas welding technique question: Most textbooks tell you to butt thin sheetmetal together then tack and weld. When I was taught gas welding at a coommunity college, the instructor insisted that all metal 1/8" or less should have a gap of the metal thickness between them. Then you tack and weld. He claimed much reduced distortion as a result.
