    FCAW (Flux-Cored) Operation Properly connect a wire feeder control cable to either the terminal strip or to the Wire Feeder Receptacle. If welding electrode positive, connect the electrode to the “+” output studs, and connect the work cable to the “-” studs labeled “GMAW, FCAW”. If welding electrode negative, reverse the connections.

    Overload Protection The DC-650 PRO is protected from excessive output currents by phaseback circuitry on the Control PC board. If the output current exceeds approximately 850 amps, the output of the machine will phase back to a low value. It will remain at a low value until the load is removed.
