The generator controls the amplitude, the repetition frequency, the duty ratio and the waveform of the operating pulses applied to the operating gap. It has a circuit device which produces control signals (112, 113) from input signals (F, tp, P, A) which represent the electrical parameters of the operating pulses, which control signals (112, 113) represent an upper (16) and a lower (17) limit of the operating pulse waveform and control the power output stage of the generator. Curve shapes for the envelope curves (16, 17) of the operating pulses which have been found to be expedient for specific erosion processes are stored in programmed read-only memories. <IMAGE>
