Abstract

PURPOSE: To facilitate the welding operation and stabilize the arc to reduce the occurrence of spatter, by determining the pulse frequency of the welding power source according to the wire supply speed in the arc welding device due to applying of the pulse voltage.
CONSTITUTION: Output part 42 of welding power source 18 is so constituted that it outputs the pulse voltage of the same frequency as the input signal frequency, and welding wire 10 is supplied by driving roller 30 and guide roller 32 of wire supply device 12 and is fed to welding torch 14. Materials 46 to be detected are provided at approximately equal intervals on one roller of these rollers 30 and 32, and the detection signal of sensor 48 which is provided for detecting these materials 46 is inputted as the said input signal to output part 42 of welding power source 18. The pulse voltage of a frequency corresponding to the rotation speed of rollers 30 and 32 is applied from output part 42 to the part between welding wire 10 and material 16 to be welded to perform arc welding, and thus, stable arc welding without the occurrence of spatter is performed.
