PROBLEM TO BE SOLVED: To provide a welding robot capable of preventing the occurrence of a trouble due to wire feeding, wherein abnormal supply of wire supplied to a welding torch on downstream side of a wire feeding device is detected by comparing a wire feeding quantity in a wire feeding means, and a wire feeding quantity in a downstream side position of the wire feeding device between the wire feeding means and the welding torch. SOLUTION: The welding robot includes a welding condition control element 17c which detects the first wire feeding quantity of a wire feeding device 16, and a wire measuring instrument 40 which detects a second wire feeding quantity in a position on a downstream side between the wire feeding device 16 and the welding torch 13. The welding condition control element 17c serves as a feeding abnormality determination means to compare the first wire feeding quantity and the second wire feeding quantity, and determines the feeding abnormality of the wire feeding device 16 based on the result of the comparison.
