Abstract
The present invention is directed to a gun arm apparatus for a resistance welding gun. The gun arm apparatus comprises a main body having a U-shaped cross-section with an opening formed between the legs of the U. The main body is formed from a relatively thin metal and the main body includes an electrode holder at one end thereof, a support at the other end thereof and an electrical terminal at the other end thereof. An electrical conductor member is fixedly mounted in the opening between the legs of the U-shaped main body. The electrical conductor member is formed from a relatively thick plate member. The conductor connects the electrode holder to the electrical terminal. A cooling water passage is positioned in contact with the conductor for carrying cooling water to cool the electrical conductor member. In one embodiment, the cooling water passage comprises at least one pipe fixedly attached to the conductor and in another embodiment, the cooling passage comprises grooves formed in the conductor.
