Abstract

A gas-protected arc welding torch device having an electrode support sleeve, electrical conductor, electrically conductive electrode clamp devices mounted on said sleeve, devices for supplying electrical current through said support sleeve and jaw for the electrode, a gas discharge and steering nozzle mounted on said electrode support sleeve and having an internal non-perforated surface of revolution concentric with the electrode and extending from the nozzle assembly in said sleeve further of said jaw devices towards the arc to form with the electrode an annular orifice, ring walls rigid outside and concentric with the electrode, arranged axially between the assembly of said nozzle in said sleeve and said annular orifice and forming an annular cooling chamber , devices for the passage of coolant liquid den and outside said annular cooling chamber with rigid walls, and devices for supplying gas into said surface of revolution adjacent to the assembly of said nozzle in said sleeve for weighing axially along the annular gas passage between said surface of revolution and said jaw devices of the electrode in heat exchange relation with the cooling liquid in said annular cooling chamber and from there to the outside, through said annular orifice.
