ABSTRACT:
In a wire cut electric discharge machine, a CPU stores a reference specific resistance specified for a machining solution according to a numerical control program, and causes a specific resistance control unit to control the specific resistance of the machining solution, and compares the machining solution's specific resistance thus controlled with the reference specific resistance, so that the CPU starts the electric discharge machining operation after confirming that the specific resistance has reached the reference specific resistance specified.
