welder/welding

As one of the previous guys said, no straight Argon for MIG, use 80/20 Ultramix from the welding store. Straight Argon for Tig only. The nice thing I like about my Tig is I can start low amps & increase as needed with foot pedal and decrease when you build to much heat in the part. I hardly ever use my Mig anymore, once in a while I'll drag it outside to tack/weld something under a truck or car.. And yes, practice,practice,practice !
