Abstract

PURPOSE: To easily detect the occurrence of wire stick by applying DC voltage of opposite polarities smaller than welding voltage between a torch and welding base metal and detecting the presence of not of any electric current by this DC voltage upon ending of the welding.
CONSTITUTION: DC voltage of opposite polarities smaller than a welding voltage is applied between a torch 20 and welding base metal 21 by a DC voltage source 6. The + side output terminal of the DC voltage source is connected to a welding voltage terminal 18 and the - side output terminal is connected to a welding voltage terminal 19. The welding voltage terminal 19 is connected to the 1st detecting circuit 8 via a Zener diode 27 and a diode 9 and to the 2nd detecting circuit 10 via a diode 11. This makes it possible to judge the end of welding by detecting the presence or not of any electric current in the 1st detecting circuit. The electric current based on the DC voltage flows in the 2nd detecting circuit and if wire stick is caused, the electric current flows and the voltage is dropped by a resistance 7 to apply no voltage to the diode 11 and the electric current is stopped in the 2nd detecting circuit. If no wire stick is caused, the electric current flows.
