Abstract

PURPOSE: To perform uniform welding by adding a voltage transducer, a voltage detector and an adder to an arc welding machine and making the arc length constant changing the wire feed speed according to the change of arc length.
CONSTITUTION: A feedback control system that makes output of an output control part 2 constant current characteristic with a voltage transducer 15 is constituted by detecting output current of the output control unit 2 that rectifies and outputs a.c. input and then making feedback control. A signal of output voltage of the output control part 2 detected by a voltage detector 17 and the reference signal of a feedback control system that detects output voltage of a motor control part 9 of a wire feed motor and makes feedback control to make it constant current characteristic are added by an adder 19. Thus, the reference signal of the feedback control system that makes welding current constant and the reference signal of the feedback control system that makes the wire feed speed constant are set by one output regulator 6.
