Abstract: The invention relates to a method for cleaning an electrode (1) used in resistance point welding, particular a cap (2) which can be placed on the electrode. According to the invention, the electrode (1) and/or the cap (2) are impinged upon with a cold medium. The temperature difference between the cold medium and the functional parts to be cleaned is greater than 80 Kelvin and the temperature of the functional parts is above room temperature. The invention also relates to an electrode (1) for resistance point welding, in addition to a cap (2) which can be placed on the electrode (1). According to the invention, the electrode (1) and/or the cap (2) has a feed direction for supplying the cold medium.

Abstract: The invention relates to a method for cleaning an electric arc welding or cutting device, particularly the functional parts thereof such as a gas nozzle, tuyère connection and the like, and removing impurities therefrom. The burner is impinged upon by a cold jet means from the media supply side thereof, wherein the temperature difference ?T between the jet means and the functional parts of the burner is>80 K and the temperature of the functional parts of the burner is above ambient temperature.
