This is an older post but do or did you find the schematic? My welder is
down and I`m looking for a schematic , thanks Tom


Lincoln will send you a WIRING diagram, but I couldn't get schematics
for the boards. I have a Square Wave TIG 300 and had to trace out
what I needed on the board. It was the post-flow timer staying on
forever, so it was fairly easy to find the bum capacitor for that
by tracing back from the adjustment pot.

If you do find anybody that has board schematics, I'd sure like to
know!

Thanks,

Jon
