This requires remagnetizing (polarizing) the laminations before using the generator again. The process is roughly as Jack describes, but I've never done it so don't ask me for more details! I have a friend who had a welder/generator that had the same problem and he used a process something like that to get it working again.
    Fencepost -- thanks , but I'm pretty familar with the theory behind generators.

    I have to admit in my haste reading and with the typo in Edgeking's original post the question or topic wasn't clear --- appologies to Edgeking.
    Jack's reply cleared that for me, though, having used portable welders in the past I've never ran into this issue. Perhaps they were a newer configuration than what Edgeking is working with.

    This brings back old memories as a kid on the farm. First learned about this from grandads old John Deere service manual.
    Aside from the old farm equipment this info. came in handy when I was 19 and owned all orginal '56 Chevy ( remember the oil bath air filter? ) which had a generator charging system --- sure wish I still had that car today.

    You could jump the terminals ( B ) and the ( G ) at the cutout relay or voltage regulator lugs --- not the ( F ) field windings.
    You just need to tap the jumper wire between the 2 lugs in which there may be a small spark --- just takes a split second and it's done.

    Sometimes google comes in handy
    http://www.hobartwelders.com/service/owners-manuals/

    Though the manual that comes up might be a newer version of machine than what you have since it talks about checking and changing brushes and no proceedures for polarlizing.
