Abstract
PURPOSE: To change over conducting circuits depending upon the magnitude of arc current and improve arc break and arc start characteristics in small current region by providing a circuit of comparing the output signal of an arc current feedback circuit and the reference signal corresponding to the two arc voltage.
CONSTITUTION: The arc current feedback circuit is constituted by an arc voltage comparing circuit 5, comparator 6, welding current detecting circuit 12 and amplifier circuit 13. The output signal of this circuit and the reference signal corresponding to the two arc voltages Er1, Er2 (Er1 > Er2) which are set according to the welding works 2 and are synchronized to changeover switches 15, 7, 8 are inputted to the comparator 6 for transistor circuits. When the arc current is larger, the feedback signal and reference signal Er2 are conducted and when the arc current is smaller, the reference signal is conducted, whereby the control signal is applied to the transistor circuit 3. Welding defect is prevented by this power supply.
