[origin: ES8704694A1] The plasma welding or cutting torch comprises a hollow torch body (1) whose interior is connected to a source of plasma-producing gas, an electrode (2) disposed inside the body (1) and electrically connected to an electrical supply conductor, and a nozzle (3) provided with a plasma outlet orifice (34). This torch is characterized in that it comprises a cartridge (60) which cannot be disassembled and comprises an annular skirt (4) assembled by screwing with the torch body (1) and having a seat (18b) for the nozzle (3) which is freely slidably mounted in the skirt (4) and applied against the seat (18b) solely by the pressure of the plasma-producing gas.
