SECONDARY CABLE FOR RESISTANCE WELDING MACHINE

摘要

PURPOSE:To provide a titled secondary cable for a resistance welding machine which conducts large current to a weld zone and which has improved heat radiatability and maintainability by inserting a cable cover formed like a coil spring onto a said secondary cable. CONSTITUTION:A cable cover 3 formed of an insulator such as a resin like a coil spring at a specified pitch over the entire length of a secondary cable 1 for a resistance welding machine is inserted onto said cable. As a result, the curving near the terminal 2 of the cable 1 is relieved and averaged like an arrow B shown by a dotted line. The concentration of the strand breakage at the specific point of the cable 1 is thus prevented and the life of the cable 1 is extended. The heat radiatability from the cable 1 is improved by the above-mentioned method and the damage of the cable is easily discovered from the outside.
