Trez,
All the industrial size TIG outfits will be 220 single phase. You should have that power even in a residential home. You might have to pull it from the panel if it's not already wired. Personally, I wouldn't mess with a 110v welder. There are a lot of choices and I'm not, nor never was a pro welder. My experience was just from shop classes and my friend's shop. I've owned 3 TIGs and 2 MIGs when I owned a machine shop but didn't do welding fulltime. I'd look at the Miller Syncrowave 180 amp welders. Lincoln makes some good ones too. I'd buy one with enough output for welding aluminum since sooner or later you'll have some aluminum or large steel project to weld.
