I have a Hobart 135, which was replaced by the 140. I really like it, but I didn't do my home work before I bought it. In college, I tig welded Al, Ti and SS, all were shielded with argon. I thought it was the same for MIG welding so I bought the Hobart MIG, then find out that Al, and SS use different shield gas from each other and from steel. The little gas bottles, if you don't have an empty, are about $120. If you're want to weld steel, Al, and SS, I would l spring for a TIG. If you add the spool gun, as mentioned above, and the three bottles of gas, you're starting to get to TIG country.

Just one man's opinion.
