I Agree, watch the papers. I picked up a lincoln Squarewave tig 175 from an awning shop that was going down the tubes. The next week the guy calls me and asked if I would want a Miller Roughneck(gas powered welder/generator)? Picked up both for under $500. If you are looking at the welders from Harbor frieght, I have an 220 dualmig from there and it is hard to use, not a lot of power settings. However I have welded alum. and steel with argon. Used, you can get a bigger unit for the same money. GPN
