I had no clue what kind of gas I am using till I went and checked. Argon/CO2. Have always Just turned it all on and weld. I have the 4 foot bottle on my Miller.
Thinking about buying a plasma. Any suggestions boys?
This is the one I have been using on my build. Works flawlessly. Used it last night to cut some brackets/welds off an old Jeep axle for a buddy, he was impressed. $425 to my door. You can same one on ebay for less, same seller too, but the ones on ebay have a 1 year warranty, buying direct I got 3 year...good guys to talk to as well.
