Abstract
PURPOSE: To change average value electric current and reduce spatters by generating pulse arc current from a switching circuit and making the width and period of the pulse current variable.
CONSTITUTION: A 3-phase AC power source 1 is dropped of voltage with a transformers 12 for welding machines, is rectified with a control recrifier circuit 13 for supplying base current, is smoothed with a reactor 14 for smoothing base current and is supplied between an electrode wire 8 of a wire supply device 7 and base metals 11, whereby the base current is flowed. On the other hand, the dropped voltage is rectified with a rectifier 17 for peak current supply and is smoothed with a smoothing capacitor 18. Further, it is converted to pulse-like voltage of about 200W2,000Hz by a switching circuit 19, and is supplied via a reactor 20 to the wire 8, whereby pulses are supplied to the load. Thence, the output pulse width is changed by a driving device 21 fluctuating the pulse width in accordance with input signals, and the output pulses thereof are supplied as driving pulses for the circuit 19.
