Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inverter controlled power source for arc welding, a power source which can enhance welding performance by measuring an output voltage and output current in a short time without being affected by noise. SOLUTION: A conductor 63 in which an output current flows is put through an iron core 22, while a conductor 64 which connects between external output terminals 58, 59 is put through an iron core 23. With a high frequency AC current supplied to conductors 15a, 15b, a change in the current flowing in the conductors 15a, 15b caused by a change flowing in the conductors 63, 64 is taken out as the change in the voltage. Thus, the output voltage and/or current supplied to a weld zone is detected to control a welding output. COPYRIGHT: (C)2005,JPO&NCIPI
