I've read alot about the welders on the market, and the threads here about them. I've narrowed it down to a MM175, Hobart 180, Hobart 175, or maybe a mm135. I want to be able to weld 1/4" steel for things like hydraulics, and also be able to weld sheetmetal. Can a mm135 weld thick metal safely with a couple passes? I would love to have a 110v welder like the mm135 or hobart 140 so that I could take it anywhere and use it. But I want to be able to weld anything I might need. I'm going to spend around $800-$900, and that includes welder, helmet, 80 gas/cylinder, tools, wire etc...
which one of these would you buy if you were getting a welder

Also, These are two plugs I have in my garage one is 250v 50amp, the other is 250v 20amp, I think I'll have to find a plug to match and wire it to the welder to fit one of these if I get a 220v welder right?
250v 50amp
