Dual-voltage MIG welders combine the versatility of welding with a 110V input with the high power output available from a 220V outlet all in one machine.
Are Dual-Voltage Welders Any Good? Dual-voltage MIG welders are an excellent option if you need the versatility of a 120V input combined with the power from a 220V power supply when available. It’s the best of both worlds, power when you need it and welding wherever the work takes you without the limitation of needing a 220V outlet.
