Weighing in at just 40 pounds, the portable Power MIG 210 MP is a multi-process welder with dual-input voltage options (120 and 230 volts), enabling the user to plug it in practically anywhere. The welder produces 20-140 amps DC on 120-volt input and 20-220 amps on 230-volt input. That’s enough welding output for 3/8-inch-thick steel and stainless materials or 3/16-inch-thick aluminum. The integrated wire feeder handles 4- and 8-inch spools and can feed 50-500 inches per minute.
