I tore the machine apart. Pot runs smooth 0 - 12K ohms. Also tested
panel/remote switch, its fine.

Other ideas before the scrap man gets it?

Id also mention..that is one of the finest welders ever made. I see
them in countless machine/welding shops..still chugging away 40 or
more years since they were new.

Ive used 20 or more different ones in shops..and have had 2 of my
own..and I really..really like this machine. Id spend the time
following the instructions and rebuild that board(s)

Pass it on to your grandkids children.
