ABSTRACT:
A spot welding gun for resistance welding of workpieces, includes a base body and a bracket, in which electrode holders are arranged, the electrodes being in turn arranged in the holders. At least one electrode holder is fixed to an actuator that enables the electrode holder fixed thereto with the electrode to be displaced in longitudinal direction towards other electrodes. To protect the electrodes a winding device with a band is arranged, the band being displaceably arranged between the contact surface of the electrode and the workpiece opposite the electrode. The winding device assigned to the displaceable electrode is connected to the displaceable electrode so that it moves at the same time as the electrode when the electrode is moved in longitudinal direction. The electrode holders and the electrodes have devices for guiding the band from the winding device axially along the electrode holders towards the electrode and vice versa.
