  • Older Airco Heliarc welder

    I have an older Airco Heliarc welder where I just smoked a transformer. It takes in 460 volts and transforms it to 120 volts and 24 volts on the output side. Does anyone know where I can start looking for a replacement transformer? Any help would be appreciated.


    It is an Airco AC/DC Heliwelder IV
    300 amps
    Serial number MG903036

    It has a 1978 Electrical diagram on the inside of the back panel.
    It was made in Montvale N.J.

    Take a look at some of the older Miller Synchrowave transformers. They may be along the same lines.
