Abstract

PURPOSE: To reduce the difference of an average current value and a peak current value, to decrease the capacity of an output control transistor, etc., and to make a device small in size by executing a high frequency pulse welding by varying a high frequency pulse frequency.
CONSTITUTION: Welding currents 11 and 12 are a pulse current of a high frequency and a pulse current of a low frequency, respectively. These pulse currents 11, 12 are supplied by bringing a transistor 4 to an opening/closing control by a signal of a controlling circuit 5. By varying a pulse frequency of the welding current, a difference between an average current value and a peak current value can be reduced, therefore, as for the transistor 4, that which has a small capacity can be used, and also with regard to a capacitor 3, a rectifier 2, a power source transformer 1, etc., as well, those of a low pressure resistance can be used. In this way, a high frequency pulse TIG welding machine can be made small in size.
