PURPOSE:To enable each welding gun performing the welding of different conditions by independently connecting a work signal feeding system, pressure signal feeding system and welding current feeding system respectively to the plural welding guns fitted to the same fitting frame and by working them individually respectively. CONSTITUTION:Plural welding guns 12a and 13a are relatively fitted displacably to the same fitting frame 11 of the wrist, etc., of a welding robot. The relative displacement is enabled by the driving means 14, 15 of a cylinder, etc. for the frame 11 fitting both the welding gun 12a, 13a, and the respective work signal feeding systems 28, 29 connected in parallel to each cylinder 16, 17 for pressurizing of the driving means 14, 15 and welding guns 12a, 13a, further welding current feeding systems 33, 34 are connected independently each other to the respective welding gun 12a, 13a. The optimum welding can be performed for different adaptive welding conditions by both welding guns 12a, 13a.
