ABSTRACT:
The EDM power supply includes a normally operative roughing circuit and a finishing circuit which is switched into the power supply at an appropriate time. The time of switching is set by a detecting circuit which determines whether or not the machining pulse on time is equal or less than two microseconds or other predetermined time periods. Because the pulse on time for finishing is generally within the time range preselected, the following circuit is then enabled.
