I have a 15 or so year old Campbell Hausfeld wire feed welder that I am trying to repair. WG3000 is the model number. The wire speed runs at the highest speed all the time regardless of where the potentiometer is adjusted. It might actually be running faster than full speed but I can't be sure. Replacement circuit board is no longer available, part number for that was WC402900AV. My first thought was the pot was just shorted and running full speed all the time but I am pretty much a beginner with electronic repair. I have done a lot of analog machine control work so I have a meter and know how to use it. I never got into any of the boards, everything in industry is just r and r anyway but I want to learn and decided this could be a good starter project. , but I ran into trouble determining the resistance of the pot, looks like it is marked 1 ohm to me but I don't know what IKA's annotation system is. No hot spots on the board anywhere. Any components I can test without removing from the board? Any help or ideas with the pot or if I should look elsewhere would be appreciated. I am working on making a circuit drawing of the board, but am not done yet.
Thanks,
Krist
