Adequate 220 voltage for MIG

I have a shop with a sub panel that is approx 150í from main breaker. I have a 50-amp double pole breaker in the main panel with #6 wire running to sub panel in shop. Iíve 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?

Well, you might be wasting your time because it is extremely doubtful that you have 220 volts. Standard voltage in the US is 240 and even then it might be a little higher.

As for the welder, it only draws 37 amperes maximum. At 150 feet with #6 copper conductors you can "pull" 50 amperes with the recommended 3% voltage drop. You are fine.
