Abstract (en)
[origin: WO2008062300A1] A plasma torch (1) consists of a torch body (2) comprising: an electrode (3) mounted centrally in the torch body (2); a nozzle (4) mounted on the torch body (2), surrounding the tip of the electrode (3) and having a first central through hole (6) for the passage of the plasma; a nozzle holder (7) whose inside wall faces the outside wall of the nozzle (4) in such a way as to form a cooling chamber (8) through which a second cooling fluid (Fl) passes; a nozzle (4) and nozzle holder (7) covering unit (10) composed of a first member (10a) that can be joined to the torch body (2) and a second member (10b) that can be joined to the proximal end of the first member (10a); the second member (10b) is provided with a second central hole (11), coaxial with the first hole (6); a channel (12) for the passage of a third, cooling fluid (F2) is formed between the nozzle holder (7) and the covering unit (10) in such a way as to reach the second hole (11); in the join area defined by the proximal end of the first holder member (10a) and the annular edge of the second member (10b) there is a plurality of concavities (13) designed to enable a part (F2a) of the third cooling fluid (F2) to flow to the outside of the second member (10b).
