ABSTRACT The present invention provides a capacitor charging circuit for a discharge type welding tool. The circuit includes a rectifier for producing rectified pulsating currents, a capacitor to be charged, a thyristor between the rectifier and the capacitor. A pulse generator receives the pulsating currents and in turn produces a pulse at each hill of the pulsating current. The thus produced pulse is applied to the gate of the thyristor which turns the thyristor on. A charge potential detecting circuit directly measures the charge potential across the charged capacitor and transfers a signal change, according to the level of the capacitor potential, to the pulse generator so as to thereby control the timing of the pulse generation at each hill of the pulsating current.
