  • Big 40 Diesel

    Ser. # JJ404151 1988 with CV-2
    New to me and just noticed that the
    D-C Volt gauge shows voltage wile not welding in DC elect Neg. and AC but when switch to DC elect Pos. shows no voltage on gauge. Seems to weld fine in DC elect Pos and shows Amps at gauge but shows no Volts while not welding. As it does in both other modes. Just wondering if I hv problem or normal ?
    Thx Greg
