has a hobart 220v mig welder sitting in his garage with a full size tank that his old next door neighbor GAVE is to him. Free, nada, zilch. My friend said I can come over and use anytime or if I had 220 in the garage I could semi permenently take it home!!!! Someday's just don't get any better. I've read many on post's (mostly Greg's) about welding techniques and which one to buy but I have no idea of the basic's of setting up a machine and getting it ready to weld. It doesn't look too complicated, I just want to be careful and not break it or me. I need to know the basic setup settings and stuff for a mig. If you have any good links let me know.
