Hey all,
I've recently picked up a Rtech AcDc tig and most importantly a good price on CK torch with built in rotary amperage control. Now I knew the R tech would need a 47K pot for the input and the CK torch is a 10K, they don't do a 47K or indeed anything close and the CK price make my eyes water too!
Plan A was maybe to find a suitable slider pot to mod, but again 47k is hard to find a slider and impossible in the correct travel and with switch. So plan B is use the 10k pot to input to a Arduino, then have that control RC type servo or stepper motor linked to a 47K pot going into the tig.
Does that sound like a feasible plan or do any one have a better suggestion? It's been while since I programmed anything but kind of sounds a interesting thing to try
