ABSTRACT:
The impulse welding device includes a transistor circuit which is operated by an impulse generator. The power transistors of the transistor circuit are operated alternately in the blocked condition and in the conducting condition. The transistor circuit is connected to a direct current power source in series with the arc which is created between the welding electrode and the work piece to be welded. The transistor circuit is shunted by an ohmic resistor which allows a spacing current to flow through the ignited arc during the impulse pauses. Since the power transistors are substantially completely blocked during the impulse pauses, the power loss will be decreased.
