PROBLEM TO BE SOLVED: To provide a welding robot in which the durability of a single-wire system power cable for connecting a wire feeder and a welding torch and the feed performance of a filler wire are increased. SOLUTION: An upper arm support 15 is cantilevered at the distal end of a lower arm 13, and the wire feeder 30 is rotatably attached to the base end of the upper arm support 15 or the lower arm 13. A hollow part is formed in a first shaft speed reducer installed on the base 11. An end of a conduit cable 39 is inserted from the base end of the base 11, extends through the hollow part of the first shaft speed reducer and a swing base 12, and is connected to the wire feeder 30. Consequently, the durability of the single-wire system power cable 50 and the feed performance of the filler wire can be increased. COPYRIGHT: (C)2011,JPO&INPIT
