It is a damn tough question, yet it is important to correctly decide has to look like the process energy source and process control. If one begins with the μPECMM (double-layer-reloading), then mostly worked with sufficiently short pulses and small current amplitudes. Critical is the situation when in the "conventional" ECMM the pulse durations are steadily reduced. The relatively large work surfaces, then also require larger currents, so that it can not be easily made it.
