Method and apparatus for separating a temperature-adhered electrode tip

摘要

A method for separating a temperature-adhered electrode tip from a workpiece wherein the electrode tip is biased in a direction away from the workpiece and a separation force is imposed on the electrode tip while the biasing force is being imposed so that a defect is not caused in the workpiece when the electrode tip or the workpiece is moved relative to the other during and/or after separation. An apparatus wherein a condenser battery is disposed in an electrical circuit including a welding gun servo motor. An apparatus wherein an electrode tip rotating device is installed in the welding gun.
