I finally found me a lincoln sa 200 welder! it was at a scrap yard taken apart and i got it for $100. the engine was last ran last year and is complete, the hood and doors on it were off but look almost new. The problem guy I bought it from says that it needs a new set of brushes and aside from that its just rusted up. I have no idea how to go about restoring the generator part of the welder. can somebody point me in the right direction. the face plate said its a SA-200-f-163 code-7789 A-841101.
