Abstract

PURPOSE: One-pass-welding is effeciently performed by using welding current of up-and-down oscillating synchro-pulsed output which profiles a running tarck of a torch tip.
CONSTITUTION: A moving distance in a normal operation is predetermined for a motor-driving control circuit (not shown). A torch-rocking control circuit is operated through the motor-driving control circuit and an oscillating circuit. And a motor 11 for moving truck and a rocking motor 15 cooperate to vertically drive a torch tip 5 along a determined track. Meanwhile, the oscillator produces a track-contouring pulse signal which is doubled by a doubling circuit, duty cycle is adjusted by a current control circuit and converted into a welding current by a wire-current- feeding circuit, and then is fed into a wire. The regulation of the welding current is such that the torch tip will have a peak current when welding the uppermost and lowest portion in groove corner, and will have reduced current when welding other area of groove
