Hello Everyone,
I have a Riland Tig welder that came with the torch hi freq start button and the two pronged connector to the welding unit. I see that Chiry ACDC tig is actually manufactured by the same people based on how it looks so maybe information about either might answer my questions.
I want to install a foot pedal in place of the torch button and that part I get entirely. What I want to do is to use the 4.5 k Ohms potentiometer in the foot pedal to control the amperage. My amperage pot is on a circuit board at the front of the unit. There are two separate micro-circuit plugs on the bottom side of the circuit board that I do get a scale of resistance when connected to a volt-ohm meter and rotate the amperage pot. One plug has three pins the other has 5 pins. Does someone have schematics for this unit that I can determine connection points for the pedal pot?
Also ... will the foot pedal adjust the amperage up to the selected amperage on the circuit board pot (which is desirable) or does it take over the complete range of 20 to 200 amps?
