Abstract
PURPOSE: To prevent breakage of machinery elements by detecting short-circuit current with a detecting device when output short-circuit occurs and stopping supply of voltage to constant electric power source for welding by a detecting signal from the detecting device.
CONSTITUTION: When output short-circuit occurs due to the contact of a fixed electrode with a parent metal by accident, output voltage of constant voltage electric power source 1 for welding drops and large short-circuit current flows. This short-circuit current is detected by detecting sections 7, 12 and detecting signals are sent to controlling section 16. When the detecting signals are received by the controlling section 16, a signal to stop supply of voltage to the constant voltage power source 1 is sent to electromagnetic switches 19a, 19b.
