Has anyone used one of these welders? What did you think about it? I found one for sale used, that had a water cooled torch,leather hose torch covering,and cart. The guy wanted $1500.00 for it. It looked like it was in decent condition. I'd say it looked to be about 5 years old,just guessing though. He bought it at an auction and did not know about it's past. Just looking for some input. Thanks for any reply!
