I've got a Cebora TIG Inverter that I want to add a pedal to, but I grudge paying £180 (that's for one from Heliarc - I'm sure the genuine item was a good bit more) for something that doesn't get used much.
I've got a pin out diagram of the connector, and all it needs is a potentiometer across three of the pins. However, I've not got any idea of what resistance will be needed, but I notice the heliarc pedals would seem to be a standard pedal, with a connector added to suit different welders.
Does anybody know what resistance pots are typically used in TIG pedals?
I can measure the voltage across the connectors on the welder if it'll help.
