Zusammenfassung:PURPOSE:To optimally execute setting of a torch position against a work by controlling the driving of a torch by using a driving pulse which is generated in accordance with a signal from a position detecting means. CONSTITUTION:It is detected that a torch 2 has reaches a prescribed position against a work 33, by a position detecting means of a deceleration sensor 12 and a dock 5, etc. Also, a distance L2 between the work 33 and a nozzle 3 is detected by using a stylus 11 and a gap sensor 10, based on a reference point for working as a reference. These signals are inputted to a voltage comparing circuit 16, etc., outputted to a shaft control part through an outputting circuit 27, and the torch 2 is positioned through a servo-amplifier 31 and a shaft driving motor 32. In this way, the torch 2 can always be held at an optimum position against the work.
