摘要

A laser machining apparatus comprises a laser oscillator, a laser processing machine and a control section, which the laser oscillator, and controls the laser processing machine. The control section comprises a preparation measures section, which controls the laser processing machine in such a way, in order to begin helpful for the laser machining, if a preparation measures instruction is output, and a mode switching, the one operating mode of the laser oscillator between a standard shaft ready mode before execution of the laser machining and a power-saving mode with a lower power consumption than the standard switches ready shaft mode, and wherein the mode switching voltage controlled in such a way as the discharge tubes, in order to switch the operating mode into the energy-saving mode, before the preparation of measures instruction is output, and a switching operation of the operating mode from the energy-saving mode in the standard shaft, which is ready to start mode, when the preparation of measures command is issued.
