GMAW arc spot welding should not be confused with Resistance Spot Welding (RSW). 1. Nick: Designing a robotic system fed by MIG wire drawn from bulk drums. (For soft wire or small diameter stainless steel wire, reduce drive roll pressure on the rear roll on a 4-roll drive to half that of the front rolls.) Output Amperage: 30-300 A. EZ-Change Low Cylinder Rack (May Be Sold Seperately): Change bottles by rolling them on or off the rack, attached to the back of the welder. It sounds like something that may not be financially fun.
