Abstract
PURPOSE: To enable the stable welding in a wide current region with one DC reactor by parallel connecting a smoothing circuit which includes a capacitor and an impedance circuit which does not include any capacitor to a fusion-welding electric power source.
CONSTITUTION: When contacts 2 are closed by the operation of a torch, an AC power source 1 is supplied to a welding transformer 3 and its output is made to direct current by a rectifying circuit 4. This direct current is applied to a welding electrode 10 by way of the main winding of a DC reactor 4. The smoothing capacitor 6 during welding repeats charging and discharging and after the end of the welding, it is discharged through a resistance 14. As a result of this, even if an arc 12 is held put out, the specified load current flows through a control winding 13 and resistance 14, and the no-load voltage generated between the electrode 10 and base material 11 becomes lower. When current supply to the load side of the transformer 3 is stopped by opening the contacts 2, the charges having been charged into the capacitor 6 are discharged through an impedance circuit C. This circuit constitution eliminates the pulsation of the current in the spray arc welding region and stabilizes the arc.
