Put my CK linear Hand Control on with 10K ohm Potentiometer works just fine the machine will use just about any Potentiometer I have a 25K, 47K and 10K Ohm Linear controllers and they all work. The machine must have a electronic controller that will use any type and adjust for it. When change the power the voltage from 3 phase to single phase it know and changes it self and this machine will take 3 phase 460V also the PFC must do that.
