Abstract

PURPOSE: To cause one globule transfer surely with one pulse current and eliminate the production of spatters by changing over the pulse current peak value to two stages in a device wherein pulse number is changed and the pulse current peak value is controlled to a set value.
CONSTITUTION: When an arc is generated on starting of welding, an electrode is fed to the work, and base electric current flows to the arc part by a base electric power source part 2 connected to a transformer 1. At the same time, the output of the transformer 1 is flowed as pulse current to the arc part by a pulse electric power source part 3 and a switching element 5. The one-off operation of the element 5 is accomplished by the command of a control circuit 13, and a frequency, a current period and one stage peak value are determined by the set vlaues of pulse frequency-, width-, and peak width setters 10W12. Next, the 2nd stage peak value is determined by the 2nd same peak value setter 23, and the value thereof is set higher by prescribed ampere than the value of the 1st stage. Thereby, the leading end of the electrode is melted in the 1st stage peak value part, and the globule transfer is carried out by utilizing the electromagnetic pinch-force thereof by that of the 2nd state.
