Abstract

PURPOSE: To obtain an arbitrary blending ration of high frequency pulse current components and pure DC componenets, by keeping one of total current or high frequency pulse current at a constant value while adjusting the other, in each power supply capacity of welding by high frequency pulse current and pure DC.
CONSTITUTION: High frequency pulse current and pure DC generating units 2, 3 receiving control commands Ih0, Id0 from respective current control circuits 4, supply currents proportional to these to an electrode 5 and a work 7 to be welded. Setting devices 4a1, 4a2 of circuits 4 output set points Ih0' and It0 respectively of high frequency pulse current and total current, and an adder 4b obtains Id0'= (It0-Ih0'), and issues a command Id0 if Id0' is positive. The potential of point A of code inverting circuit 4d is 0, and an adder 4e delivers Ih0' as Ih0. When Id0' is negative, a limiter circuit 4c sets Id0 to 0, then point A in the circuit 4d becomes positive polarity, so that a command Ih0'-It0 may be obtained. As a result, the adder 4e delivers It0 as Ih0. When Id0' exceeds the pure DC power supply maximum output defining command value Idp, the circuit 4c defines it to Idp.
