PROBLEM TO BE SOLVED: To easily execute the cut-off even to a quenched steel having high hardness, to prevent the breakage at an early time and the rapid wear of an edge for cutting off and to lengthen the service life of the edge for cutting off by cutting off a softened part by locally heating a part to be the cut-off part of a wire rod, or loading the concentrated stress to cut off it into pieces. SOLUTION: The wire rod W is forcibly and intermittently fed out through a wire guide 3 by pinching and rotating with the upper and the lower of one pair of rollers 1, 2 and the fed-out wire rod is bent into the coil state or the other shape by pushing to a die 4 for bending. One pair of positive and negative (+, -) electrode tools 15, 16 for generating Joule's heat are brought into face contact with the portion (a) to be cut-off of the wire rod to cut off at the outlet part 3a of the wire guide 3 in the wire rod working machine, and under softened state by generating the heat with the conduction of electric current, the wire rod bent by loading the tortion or the shearing force to this portion, is cut off into the pieces from the following wire rod.
