ABSTRACT:
A set of indicator lights, preferably of the light emitting diode type, are used to provide readout from the gap to indicate a gap open circuit condition, a gap normal machining condition, or a gap short circuit condition, respectively. Three lights are preferably contained in a vertical array to give the operator an exact indication of what type of machining is being carried on and hence inform him as to what correction should be made by way of servo feed adjustment, change of machining current, or the like.
