    Looking for PowCon 300SM Wiring Diagram

    Hi, I have been welding my whole life now retired so just for fun at home.

    I just purchased a powcon sm300 welder that it has a couple of circuit boards in it. The welder works but I donít think it is working properly. There is a three position toggle switch that changes welding modes. I suspect this switch is not operating properly and would love to see a wiring diagram for it.

    or if anyone knows where or how to get the service manual I have looked in the operations manual and there is nothing.
