て結着して成る。 The purpose of the present invention is to obtain a device free of such inconveniences, and an electrode holder 1 is provided at the tip.
and a gun arm main body 3 having a support member 2 at the tail end, a conductor 5 for connecting the holder 1 to a secondary conductor terminal 4 at the rear thereof, and a water passage 6 for cooling. The main body 3 is constituted by a frame body having a substantially U-shaped cross section and an opening 7 on one side, which is made of a bent relatively thin plate, and the conductor 5 is constituted by a relatively thick plate made of copper alloy. The conductor 5 is fitted into the opening 7 and bonded together, and the water passage 6 is constructed of a copper alloy pipe, which is overlapped and bonded onto the conductor 5.

した。 The support member 2 is fixedly installed in the opening 7 at the tail end of the main body 3, and the conductor 5 is attached to the support member 2.
The conductor 5 is in-routed and brazed to increase the strength of the tail end of the main body 3 where a large bending moment is applied when pressurized, and the supporting member 2 is made of a copper alloy. It is connected to the secondary conductor terminal 4 through the support member 2, and a through hole 6a for a water passage connected to the copper pipe is bored in the support member 2, so that the support member 2 has a cooling effect against the heat generated by electricity. I made it possible to obtain.

の効果を有する。 As described above, according to the present invention, the conductor 5 is constructed of a relatively thick copper alloy plate separately from the water passage 6, and it is possible to obtain a relatively large current capacity. Furthermore, the conductor 5 is fitted into an opening 7 on one side of the frame constituting the main body 3 and acts as a member for reinforcing the frame. It has the effect of increasing strength.
