    The input voltage is 110.
    I found a burned out transistor on the pc board today and replaced it.
    that didn't work.

  5. at a guess its an inverter based welder. If you have put in 230v then the chances a lot more components have been fried. you could realy do with a circuit diagram.How was it managed to be plugged in to 230v as 110v and 230v plugs are different

    The hybrid section is probably smoked, the blue section, if it is you will not be able to fix it.
