PROBLEM TO BE SOLVED: To improve a mounting structure of a welding torch mounted to a wrist part of an industrial robot. SOLUTION: The welding robot has a rotation transmitting means in which the upper part of the welding torch with a rotation mechanism is supported freely rotatably by a bearing arranged inside a coupling mechanism of the wrist part and the torch provided at the lower part of the wrist part and which transmits the rotation of a sixth axis of a manipulator to the welding torch with the rotation mechanism, a rotating axis of the welding torch with the rotation mechanism and a wire insertion axis inside a conduit for wire feed and electric power supply connected to the welding torch with the rotation mechanism are aligned, a distance is provided between the center axis of the sixth axis and the rotating axis of the welding torch with the rotation mechanism, and the welding robot has an electric power supply means to supply the electric power supplied by the conduit for wire feed and electric power supply to the welding torch with the rotation mechanism.
