Mig welder

Consider a used "brand name" welder rather than a new "cheap" one. Also it might not be a good plan for bodywork, but for most of the stuff I do, I use straight CO2. CO2, just like for soda drinks, is a liquid, and cheap, so a bottle lasts a LONG time. If you EVER think you may want to "do more" consider a dual voltage unit. I have a couple of MIGs, a little Lincoln 140 120V, and a larger Lincoln 180 240V. I wish after I'd bought it I'd gone dual voltage, although back then there weren't too many choices in that direction.
