Abstract

PURPOSE: To perform good welding with simple constitution by synchronizing the angular speed at which a welding torch turns to the angular speed at which a member to be welded and a holding member turn relatively.
CONSTITUTION: When a turntable 9 is rotated at a constant speed by a motor 14, a rotary encoder 15 rotates simultaneously, and the output thereof inputs to one input terminal of a comparator 18. The output of a rotary encoder 17 is being inputted to the other terminal, and the output voltage or pulse number signal corresponding to the difference of both inputs is being outputted to a motor driving circuit 19. Since the circuit 19 revolves a motor 13 in a manner that the output of the comparator 18 goes zero, the motor 13 rotates at the same angular speed as the angular speed of the turntable 9. The arc voltage is detected by a voltage detector 21 and is compared with reference voltage in an arc length control circuit 22, according to the differential voltage thereof, a motor 23 is driven. The arc length is controlled by the forward and backward running of the motor 23.
