PROBLEM TO BE SOLVED: To reduce the kink and deflection of welding wires and to smoothly feed and switch the welding wires through the inside of conduit cables in a welding equipment using an articulated welding robot. SOLUTION: The welding equipment comprises an articulated welding robot 8 which has a welding torch 7 having at least one arm and an arm bearing part 2 for freely rotatably bearing the arm, and freely fixedly and movably mounted on the arm 6, a plurality of welding wire feeding devices 13a, 13b mounted on the arm bearing part 2 to selectively feed the plurality of the welding wires 20, 21 to the welding torch 7 and to drive the same to pull back the wires therefrom, and a switching unit 14 which is interposed between the welding wire feeding devices 13a, 13b from the welding torch 7, is mounted on the arm 6, and selectively switches the feeding of the plurality of the welding wires 20, 21 to the welding torch 7, and a plurality of welding wire supply sources 11 which are connected to the plurality of the welding wire feeding devices and are arranged apart from the articulated welding robot 8.
