Abstract

PURPOSE: To produce a Dc welding device which injects a wire material in spherical shapes with a small size at a low cost by interrupting the DC voltage supplied to a control circuit intermittently by using a timer circuit and a semiconductor switching element.
CONSTITUTION: During the period when a timer circuit 60 generates an output "1", a semiconductor switching element 56 is conductive, and depending upon whether the DC voltage of an AC-DC converter 50 for signal supplied through this is larger or smaller than reference voltage, an electric discharge time constant is changed over to CR1 or OR2, whereby the voltage formed between output terminals 42 and 43 is controlled to the constant voltage of a value smaller than the max. voltage. During this time, a wire material assumes a spherical shape. During the time when the circuit 60 generates an output "0" the element 56 is nonconductive, and the charging time constant of a control circuit 54 is fixed at CR1 and the voltage formed between the output terminals 42 and 43 is controlled to the max. voltage, so that the wire material made into a spherical shape is injected.
