I Wanna Switch

Co2 welding gas is really machine specific. Most do not run it correctly and even fewer 120 volt machines do well.(older Miller passports did real well) The 120 volt units run out of arc voltage, and you lose some of your top end.. I use it in my Esab CaddyMig 160, and it's really perfect..The $2.00 fill was nice for a 25 pounder..C25-C10 is run in my larger higher output Thermal arc LM-200 (330 amps at 28 volts measured output)

Be sure to wear the appropriate respirator when working with mold steel. I've heard it's hazardous to breathe, same as producing dangerous fumes when welding galvanized metal.

Sorry... I just couldn't resist.
