摘要：Disclosed is a plasma torch comprising a torch body, an electrode that is disposed inside the torch body, a nozzle which is provided with a central nozzle port and is positioned so as to cover the electrode separated by a plasma gas duct formed between the same, and a protective nozzle cap. Said protective nozzle cap is equipped with a discharge port that is located at the forward end face thereof and lies opposite the nozzle port as well as an annular secondary gas duct which is arranged within the protective nozzle cap and is connected to the discharge port. The protective nozzle cap is placed so as to be electrically insulated relative to the electrode and the nozzle. The inventive plasma torch further comprises a secondary gas conduit section that is provided with at least one passage. The disclosed plasma torch is characterized in that the secondary gas conduit section is disposed between a secondary gas inlet and the forward end of the secondary gas duct inside the secondary gas duct while the secondary gas duct is embodied in such a way between the secondary gas conduit section and the forward end thereof that the secondary gas duct conveys the secondary gas (SG) at an angle to the longitudinal axis L of the plasma torch in the direction of the forward end of

the plasma torch after passing the secondary gas conduit section and a secondary gas duct section which extends substantially parallel to the longitudinal axis L of the plasma torch, and then delivers said secondary gas (SG) to a plasma jet at an essentially right angle to the longitudinal axis L of the plasma torch.
