Howdy yall! I am back with more questions. I just picked up a daihen argo 300p. Actually the guy is letting me see if it works then we do the deal. He is my shop neighbor. It comes with a tweco tc900, a torch and their version of controls. Also has translation paper. It is a three phase only unit. I am dont know what kind of three phase it is. Any ideas. It has pulse and a bunch of other settings. Should be a sweet secondary rig. I just got an old syncrowave 250 as my primary unit. But an inverter tig would be sweet. Any info or places where I could get info would be sweet. Thanks again.
