Abstract
PURPOSE: To strengthen the smoothness of the DC voltage impressed on the welding load, by installing a secondary winding to the reactor for smoothing of the secondary circuit of the transformer and connecting the secondary winding to the condenser for smoothing, in the single-phase full-wave rectifying power source circuit of the DC arc welding machine.
CONSTITUTION: The connecting point of a DC reactor 9 for smoothing and its secondary winding 9' is connected to the positive side output terminal of a rectifying circuit formed with rectifying diodes 2 at the secondary side of a transformer 1, and a welding load composed of arcs 6 is connected between one end of the reactor 9 and the negative side output terminal of said rectifying circuit. Moreover, a condenser 4 for smoothing is connected between the other end of the secondary winding 9' and the negative side of the rectifying circuit. The DC reactor 9 and its secondary winding 9' are connected to each other so that the flux generated by the electric current flowing through them may be arranged in the same direction. In this way, a DC voltage which is excellent in the smoothness can be impressed on the welding load, even when the condenser 4 for smoothing has a smaller capacity when compared with conventional ones.
