簡単にする等の効果を有する。To explain further, the pair of support plates 4, 41 are connected to the pair of power supply terminals 3, 3 at their respective roots and are prepared as power supply members extending forward, and the pair of support plates 4, 41 are connected to the pair of power supply terminals 3, 3 at their respective roots and are prepared as power supply members extending forward. 6,
6 is not only supported by the support plates 4, 4 via the shaft 5, but also supplied with electricity via this. The power supply between the gun arms 6, 6 and the support plates 4, 4 can be achieved by simply providing an insulating means on the shaft 5, for example as shown clearly in FIG. An annular insulating plate 10 is attached to 3
It is sufficient to provide a step and a pair of cylindrical insulating layers 11, so that one of the pair of gun arms 6, 6 can be connected to one of the pair of support plates 4, 4 through its inner surface. , and the other is in contact with the other from its inner circumferential surface via the shaft 5 so that power can be supplied thereto. In this way, according to the present invention, 1
A pair of support plates that support a pair of gun arms via shafts are connected to a pair of power supply terminals on the front surface of a welding transformer at each root, and are used as power supply members between the terminals and the gun arm. Therefore, the above-mentioned disadvantages of the conventional type having a separate flexible power supply member can be eliminated, and the configuration can be simplified.
