Abstract

PURPOSE:To optimize an assist gas feeding and to perform an optimum working by changing the pressure or flow amount of the assist gas fed to a working place by controlling an adjustment valve on the way of moving a laser torch. CONSTITUTION:The assist gas AG of an oxygen, etc. is fed to a laser torch 16 via a feeding pipe 17. An electro-magnetic type pressure adjustment valve 18 is provided on the way of the feeding pipe 17. The assist gas in the optimum state is fed by controlling the pressure adjusting valve 18 according to the program set in advance in compliance with the conditions by the operation panel 26, etc. for driving the memory 25, servo motors M1-M6 provided on a CPU 20. With the machine of this composition the optimum machining can be performed.
