Description
【発明の詳細な説明】 ［考案の目的］ （産業上の利用分野） この考案は電気抵抗溶接機のうちの点溶接用電極の構
造として用いるものである。DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) This invention is used as a structure of a spot welding electrode in an electric resistance welding machine.

を交換すれば不経済である。(Prior Art) As shown in FIG. 1, the conventional electrode structure is only provided with a water cooling hole 2 in the electrode main body 1. The use limit is not known from the external appearance, and the electrode is excessively used. It wears and becomes thin as shown in FIG. 5, and at the time of welding, an appropriate pressing force cannot be obtained, and poor welding occurs. In addition, it is uneconomical to replace the electrodes early to prevent the occurrence of defects.
（発明が解決しょうとする問題点） この発明は、作業中使用限界が簡単に、且つ正確に分
かるようにするものである。(Problems to be Solved by the Invention) The present invention is to make it possible to easily and accurately determine the working limit during work.

小径穴３を設けた構造の電極とする。[Means for Solving the Problem] (Embodiment) As shown in FIGS. 2, 3, 4 and 6, a depth equal to the service limit 5 is formed at the bottom 2 a of the water cooling hole 2 of the electrode body 1. The electrode has a structure in which the small diameter hole 3 is provided.
（作用） 以上の構造であるから、電極が使用限界に達すると第
６図の状態となり小径穴３から冷却水が吹き出す。(Operation) With the above structure, when the electrode reaches the use limit, the state shown in FIG. 6 is reached, and the cooling water is blown out from the small diameter hole 3.
［考案の効果］ （イ）水冷穴の中央又は内周に複数設けてあるため方向
性が限定されず、取付が簡単である。[Effects of the Invention] (A) Since a plurality of holes are provided at the center or the inner periphery of the water cooling hole, the directionality is not limited and the mounting is simple.
（ロ）電極は必ずしも垂直に使用するとは限らず、傾け
て使う事が多い。このような場合にも取付方向による機
能上の差が発生にくい。(B) The electrodes are not always used vertically, but are often used at an angle. Even in such a case, a functional difference hardly occurs depending on the mounting direction.
