    Post Lincoln Weldenpower 225 Code 9010

    The output of this welder when running is only 50 volts at the 110 AC outlets. I only get a small spark at the stinger. The DC power at the slip rings is 31 Volts. The output from the stater excitation winding is only about 18 Volts measured between leads 4 and 5 at the full wave rectifier diode. I would appreciate any help on what to look for from here.

    If anyone knows what the correct output is for the exciter winding and for the slip rings I would greatly appreciate that information.

    I don't have the specific values you're looking for but voltage across leads #4 and #5 is AC if you weren't already aware.

    With an almost doubled voltage thru the bridge rectifier makes me suspect it may possibly have one or more failed diodes and giving you false readings. Have you disconnected it and tested for such?

    I own a machine just like the one you have and had a problem that sounds much like yours. The problem was one of the positive diodes had failed. I replaced both positive diodes and the problem was solved. Iím just a welder and not a mechanic, but I hope this helps.
