Abstract
A plasma cutting torch has a torch body comprising an electrode and a nozzle, and structure for mounting and connecting the torch body. It further comprises a torch support (A) defining a first series of fluid passages (7, 8, 10, 4, 47, 50, 54) connectable to respective circuits of fluids and a first bearing surface (9); a unitary assembly of torch body (B) comprising the electrode (28, 280) and the nozzle (36) and comprising a second series of fluid passages (25, 27, 38, 39, 42, 48, 49, 55, 56) and a second bearing surface (21); and a quick coupling (D) to assemble the assembly of the torch body to the support for the torch body with the first and second bearing surfaces bearing axially against each other and with the passages of the first series communicating with the respective passages of the second series. At least one of the fluid passages of the second series comprises an end portion (40, 58, 59) projecting relative to the second bearing surface (21) and adapted to be received within a recess (3; 47, 54) of the torch support (A) defining a portion of a passage of the first series.
