Came across a good deal on a Thermal Arc foot pedal - it has a 5 K pot. The current control on the front panel of the HF Tig is a 10K. It is wired up as a pot (not a rheostat) - my plan is just to add a connector and a switch to the front panel and use that to choose which control to use. Anybody have any idea of the inner workings of this beast? Would the 5K pot in place of the 10K cause any problems? I'm tempted just to wire it up and see what happens. The schematic in the manual is leaves a lot to be desired.
thanks in advance for any advice
Mike
