I have an old 220v welder that did not work today when I tried to use it. Would not even turn on. I measured the voltage at the plug and got a reading of 120 volts on one leg and 55 volts on the other leg for a total of 175 volts in the plug. I am guessing there was not enough voltage to allow the welder to operate. What would cause one leg to be so low in voltage and what would be the solution?
