Abstract

Torche à plasma (102) ayant un corps principal comportant une chambre plasmagène (8) et un premier circuit d'alimentation (C) en gaz de travail débouchant dans ladite chambre plasmagène (8) pour alimenter ladite chambre plasmagène (8) en gaz de travail. Un deuxième circuit d'alimentation (E) en gaz d'amorçage débouchant dans ladite chambre plasmagène (8) permet d'alimenter ladite chambre plasmagène (8) en gaz d'amorçage. Le deuxième circuit d'alimentation (E) en gaz d'amorçage est au moins en partie distinct du premier circuit (C) d'alimentation en gaz de travail. Installation de travail à l'arc plasma comprenant une telle torche et procédé de mise en oeuvre.

Figure imgaf001
Plasma torch (102) having a main body having a plasmagene chamber (8) and a first supply circuit (C) of working gas opening into said plasma chamber (8) for supplying said plasma chamber (8) with job. A second feed circuit (E) for priming gas opening into said plasmagene chamber (8) supplies said plasmagene chamber (8) with starting gas. The second feed gas supply circuit (E) is at least partly distinct from the first working gas supply circuit (C). Plasma arc work installation comprising such a torch and method of implementation.
