<p>The torch has a conical cathode (120) with a point (20) and a half-coupling (200). A cathode screw (300) with a half-coupling (400) fixes the cathode, in operational position, in a cathode-gate (22) by the application of pressure on the cathode. The half-couplings (200, 400) cooperate to form a coupling, between the cathode and the screw, allowing the transmission of a traction force from the screw to the cathode. The point is present on a conical part of the cathode, and penetrates partially a central cavity of an anode to form a space between them to produce an electric arc plasma generator and a passage for a plasmagene gas towards a plasma output opening.</p> |
