The bottom (20) of the nozzle (12) comprises an axial conduit (22) for ejection of the plasma jet, and its lateral wall (24) surrounds the electrode (10) and delimits with this latter a substantially annular supply space (26). The torch head comprises structure (38) for the flow of a plasmagenic gas in the annular supply space (26) in a substantially axial direction. The end surface (16) of the electrode (10) delimits with the bottom (20) of the nozzle (12) an annular space (29) for lamination of the flow of the plasmagenic gas. For use in plasma cutting torches.
