Abstract
Guide tube for an arc welding gun. The normal threaded connection between the guide tube in an arc welding gun and the holder for same has been improved for the purposes of electrical transmission by utilizing tapered threading for same. Particularly it has been found that the electrical conductivity through said parts is substantially improved if such conical threading is of such design that the conicity of the thread is at a ratio of 1:16 .+-. 20 percent.
