Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a contact tip for a welder by which a wire can be smoothly fed without being blocked.SOLUTION: A contact tip for a welder is mounted on a tip of an adaptor 11 of the welder, and has a wire feeding aperture 2 through which a wire 10 for welding having a circular cross section is inserted from a base end part 1a contacting the adaptor 11 to a tip 1b. In the contact tip, a bent part 3, which is bent in a circular arc shape, is formed on an intermediate part of a contact tip body 1, and the bent part 3 is pushed and collapsed from both sides in a direction orthogonal to a circular arc surface, whereby the wire feeding aperture 2 is so deformed as to have a cross section of a long circular shape. 【課題】ワイヤが詰まることなく円滑に供給できる溶接機用コンタクトチップを提供する。【解決手段】溶接機のアダプタ１１の先端に装着され、このアダプタ１１に接する側の基端部１ａから先端部１ｂにかけて溶接用のワイヤ１０を挿通するための断面円形のワイヤ送り出し孔２が形成された溶接機用コンタクトチップであって、コンタクトチップ本体１の中間部に円弧状に曲がった屈曲部３が形成されているとともに、この屈曲部３が円弧面に直交する方向の両側から押し潰されることにより、前記ワイヤ送り出し孔２が断面長円形に変形されているものとした。【選択図】図１
