Abstract

PURPOSE: To provide a titled welding machine of simple and sure adjustment of the peak value of pulse current by so constituting the same that the peak value is beforehand set according to the combinations of the material of a wire, its diameter and the kind of shielding gas and said set value can be changed over and selected at the welding.
CONSTITUTION: The current supplied from a DC power source 7 is flowed to an arc load 3 through a switching circuit 8, a DC reactor 10 and a detector 5. A control circuit 6 turns the circuit 8 on and off and controls the welding current so that the peak value of the detected 5 welding current equals to the set value. When the circuit 8 is off, the welding current is flowed through the reactor 10, the load 3, the detector 5 and a flywheel diode 11. In this case, the circuit 8 controls the current immediately when the peak value of the welding current goes higher or lower than the set value, thereby controlling the peak value over the entire pulse.
