In this paper, heat treatment on the cutting device for automatic welding electrode is proposed. The electrode can be fed continuously by general automatic welding. When the leading end of wire is bent, it must be cut with the constant length. The wire has been cut by manual method previously but the automatic cutter device is proposed and designed in this study. These new device parts are designed and the heat treatment of cutter is determined analytically. The numerical three-dimensional analysis is carried out by means of DEFORMTM-HT, the common heat-treatment software. The meshes are divided with tetrahedral elements. As the result, the highest hardness is observed at the end edge of cutter and especially the hardness at edge is reached even HRc 64.3. The layer, 90% of which consists of martensite structure, is extended to the end edge of cutter. And the layer, 50% of which consists of the micro-structure, becomes its middle area. Because the mechanical property can be predicted by this analytical approach, it is not necessary to have any onsite heat treatment. The life of cutter can be improved by using this study result.
