Abstract

PURPOSE:To provide a discharge working method and a device therefor, wherein an inspecting pulse selecting and setting one or two or more of crest value, pulse width and waveform so as to facilitate inpection and discrimination is incorporated into the row of working pulses and supplied to the working gap thereby carrying out inspection, detection and discrimination of the gap condition.
