Welding Stainless Steel - shielding gas question

[Mathius]

I welded steel with pure Argon once by mistake. The metal didn't flow out like normal and piled up. Not very pretty.

You better check your setup again. I use straight 100% argon full time with my mig on mild steel. It's what we used in school too mostly. Easier than switching the tank everytime a student wanted to weld aluminum.

I've used it to weld stainless, but it didn't come out well, of course I was pushing my little 110 to the limits to weld 3/16" stainless, so that probably has a lot to do with it.
