ABSTRACT:
An electroplating cell having soluble and insoluble anodes is provided with a primary power supply having a positive terminal connected to the soluble anodes and a negative terminal connected to a cathode including workpieces to be plated. An auxiliary power supply has a positive terminal connected to the insoluble anodes and a negative terminal connected to the negative terminal of the primary power supply so that the voltage applied to the insoluble anode is equal to the sum of the voltages applied by the two power supplies.
