I need opinions...

Ok, last semester i had a welding class and did quite a bit of welding. Well, i fell in love with the tig and i'm looking to buy one. I am going to use it for exhaust work because its easy to work with and it leaves seamless beads. My question is, has anyone ever used a 120V Tig machine? The tig i always worked on was 220. I don't have much money to spend on this but i found one for $400 that i might get if its worth it. I've never heard of the brand but here are the specs on it, let me know what you think...

400 bucks? fair price........not great, not bad....but decent price......pick it up and rock it!

i took two years of welding at a vo tech i think that welders kinda small but you said you were going to use it to do mufflers thats probably ok 85 amps isn't much but good luck

Only down side is you don't have a pedal like normal GTAW machines have. So I think once you strike the arc then the only way to adjust it is having a short or a long arc. And the air cooled torch kinda stinks... but 400 bucks you Can't beat it... Check out miller has a comparable welder... similar size and all but I think its more like $1,000 or more if I'm not mistaken...

But like I said 400... that would be nice to have to do little sheetmetal stuff... like blower boxes and whatnot...
