Zusammenfassung:	An excellent welding tip in the feed stability of a wire and in the release capacity of foreign matters and in the stability of current control and a process for manufacturing such a tip economically was disclosed. A sectional shape of a guide hole (31) opened and provided to a welding tip (30) is made by forming a wire in a passable non-circular shape. The sectional shape of the guide hole may be a polygonal, elliptic or approximate shape to each of them. In the case of making the sectional shape of the guide hole polygonal, it is more preferable to make it a polygon circumscribing on a circle, for example, such a polygon circumscribing on a larger circle than the outer diameter of the wire to be inserted into the guide hole by 0.02 - 0.20mm in diameter. Specifically, it is preferable to arrange it with a triangle.
