i was thinking duff diodes, they are the usual thing apart from capacitorsAh yes, I see now I've looked at the pdf. Scr based chopper on the output for weld current control.
no power from outlets eitherOr duff thyristors... Does it make power but doesn't weld?
he said he has tested caps which leaves diodes, ive known them to come off beforeDuff excitation caps or rectification diodes in the rotor then...
Open winding is also a possibility
hopefully its just the diodes but if it has to be open winding the armature is probably cheapest to get rewoundArmature is where they go
It's one of them ally squirrel cage armatures don't think it can be rewoundArmature is where they go
