Abstract

PURPOSE:To make control using electronic circuit possible and to reduce spatters during welding by increasing the impedance between the emitter and base of a transistor for controlling outputs in the state of short circuiting and decreasing this in an arc state. CONSTITUTION:An output control circuit 12 receives the output (c) of a short circuit arc discriminating circuit 11 and generates an output (d). Here, the average base current IBD of the circuit 12, that is, the average output of a welding power source is determined with an average output setting circuit 13. Next, the output of the circuit 12 is applied between the emitter and base of a transistor 5 to operate the TR5. At this time, the impedance Z between the emitter and collector thereof is like (e). More specifically, the TR5 is employed for the main circuit of the welding power source, and the welding arc is controlled by increasing the impedance Z during short circuiting and decreasing this during the arc. The output of the welding machine is regulated by regulating the impedance Z0 of the average TR5.
