Hi folks. I've got a problem with my old SIP Autoplus 150. The wire speed dial makes no difference to the actual wire speed. I've had the welder for many years and it's always been very reliable until now.
The wire speed changes with the power setting as is expected, but there's no change using the dial. I suspected the potentiometer, but I've removed it from the PCB and metered it out and it is working as it should be. The relay is clicking, the gas valve is opening, and I can weld with it, but the welding is bad, because I can't adjust the speed.
Any ideas gratefully received
