Abstract
PURPOSE: To generate pulse current and base current and reduce the size of a pulse arc welding device by turning a transistor on and off in such a manner that the detected value of the current flowing through the TR and a DC reactor attain pulse and base set values.
CONSTITUTION: At the welding, current flows from a DC power source 1 and a capacitor 2 through a transistor 3 and a DC reactor 4, passes through an arc part B then through a current detector 7. When the detected current rises up to the pulse set value (ip) of a base output setting circuit 41, the output of a driving circuit 9 commands a transistor 3 so as to switch it off. At this time, the energy accumulated in the DC reactor passes as current through the arc part B, circulates through the detector 7 and a diode 5, and decreases gradually by a constant value from the set value (ip). Then, the circuit 9 switches the TR3 on, and repeats this operation in a pulse period (tp). Next, in a base period tB, the output of the circuit 41 changes over to the base set value iB, and the operation similar to that mentioned above takes place, whereby pulse arc welding is accomplished.
