ABSTRACT:
A C-shaped spot welding gun has its movable electrode extending from one arm of the gun's C-yoke. An air cylinder for moving the electrode is attached on the opposite side of the arm. A package of parallel copper strips is bent to U-shape and surrounds the arm below the air cylinder. One end of the U-shaped flexible conductor thus formed is attached to a fixed current connection member on one side of said arm, whereas the other conductor end is attached to a movable current connection member slidable in a guide on an opposite, parallel side of the arm. The movable current connection member is carried by the moving electrode by means of current conducting coolant pipes.
