Abstract
The present invention relates to a control loop to be used in a system for stripping a coating from a part. The control loop comprises an electrometer for measuring a potential between the part and a reference electrode and generating a voltage output signal, an operational amplifier for comparing the voltage output signal to a set point voltage and for producing an output signal to be used to reduce the difference between the voltage output signal and the set point voltage, and a high current power transistors for supplying a current to the part.
