Can you run a 220 volt welder on a 20 amp breaker?

Yes, you can run a 220-volt welder on a 20-amp breaker, but it depends on the welder's amperage requirements. If the welder draws more than 20 amps, it could trip the breaker or damage the welder. It's essential to check the welder's specifications and ensure that the circuit can handle the load safely. If the welder requires higher amperage, a breaker with a higher rating may be necessary.
