I was on here a while back trying to get some help with this mig/flux welder. It had a bad rotary switch. The ideal way would to get the exact switch, but that didn't happen with such an old unit. I had a few people help me out and I got the proper model number and schematic drawing. I'm not good at this stuff, so I need a lot of help understanding what exactly to do. I have the two blue wires which I believe are the main power cord supplies on 9 & 11 because according to the switch truth table they are always on. Next I found what I believe is #1 or start wire, comes closet from core out of the plastic bobbin, sleeves single copper wire. I hooked that up to number 10. I have 2 double sleeved wires left and 1 single sleeved. And of course the fan and power light wires.
