  • Adequate 220 voltage for MIG

    I have a shop with a sub panel that is approx 150’ from main breaker. I have a 50-amp double pole breaker in the main panel with #6 wire running to sub panel in shop. I’ve never had a reason until now to wire 220v, but plan on getting a Hobart 210mvp or 230 Ironman. Am I wasting my time wiring 220v for either of these welders with my current setup? Will the voltage loss be too much for the size wire and distance?

    For the most part you probably be welding below the maximum current/voltage draw of the welder, I don't think you will have a problem... Manual states its power usage (at 30% duty cycle) is 6.3 KW (6,300 watts)....If you do the math the amperage draw is only about 28 amps, not real big load...

      Nothing sounds odd about that to me. You will definitely appreciate a higher voltage machine.

      240 volts, not 220, though. One day I will live long enough to see the misnomer disappear.
