Abstract: The invention relates to an electrode (16) for a welding torch (17) or a cutting torch, comprising a main body (1) and a tip (3) arranged on an end surface (2) of the main body (1). The main body (1) is designed as a hollow body that is open on at least one side. On a side opposite one of the tips (3), the main body has an opening (4) for introducing a cooling medium into an interior space (7) of the main body (1), and at least two regions (5, 6) in the interior space (7), the two inner diameters of which are different from one another, and a transition region (8) located between the two regions (5, 6) having an inner diameter that decreases in the direction of the tip (3).

Abstract: A TIG torch for welding, soldering or coating, wherein an electrode is radially surrounded by an inner gas nozzle as far as the electrode tip. A first gas flow in the direction of a workpiece surface through a gap between the inner lateral surface of the inner gas nozzle and the lateral surface of the electrode. The inner gas nozzle is fastened to a sleeve-shaped inner gas nozzle carrier and is surrounded by an outer gas nozzle fixed to an outer gas nozzle carrier or an outer gas nozzle. A second gas flow in the direction of the workpiece surface between the radially outer lateral surface of the inner gas nozzle and the inner lateral surface of the outer gas nozzle. An electrically insulating element is arranged between the inner gas nozzle carrier, inner gas nozzle and/or electrode and the outer gas nozzle carrier and/or outer gas nozzle.
