There was a problem that the strength of the joint was weak and unstable. Furthermore, in order to prevent changes in welding conditions due to an increase in electrode temperature when welding is performed continuously, it is necessary to add a cooling device to the electrode, resulting in a problem that the electrode structure becomes complicated. Figure 1 shows the conventional electrode structure, where (1) is a fixed electrode, (2a) is a movable electrode, and (11) is a movable electrode.

In addition, as shown in Fig. 3, in the case of joining the contact (14) and the contact spring θ made of copper alloy, a fillet (Y) is formed at the joint of the workpiece (X) without using a brazing material. This has the additional effect of improving arc resistance. Furthermore, the welded parts of the object to be welded <X> and both electrodes (1) and (2) are covered with the liquid (5a), and the liquid temperature is maintained constant by the liquid temperature control device, so the welding area is always good. In addition to providing a cooling effect,
Welding conditions are made constant, welding can be performed stably, and variations in joint strength can be reduced. Furthermore, as in the conventional example shown in FIG.
