摘要： A welding torch includes a main body and an end portion suited to be fed through the main body with a welding wire and a shielding gas. The end portion includes a welding unit electrically powered and provided with an internal channel for the passage of the welding wire. A conveyor element is provided with an outlet mouth to allow the welding wire to move out of the welding unit and to allow the shielding gas to be conveyed outside of the welding unit. Electrical insulation means are interposed between the welding unit and the conveyor element with an insulation portion made of an electrically non-conductive material. The welding torch includes the conveyor channel suited to convey the shielding gas from the main body to the outlet mouth of the conveyor element. The conveyor channel is delimited at least partially by the insulation portion.

摘要： A connection system connects a plasma torch to a generator to allow the passage of electric current, the passage of an operating fluid, and of one or more control signals between the generator and the torch. The system includes a first connector and a second connector that are removably connected to each other. The first connector includes a first current-carrying terminal and the second connector having a second current-carrying terminal. The current-carrying terminals are suited to be mutually connected to each other. The first connector includes one or more electric terminals. The second connector includes one or more electric terminals, the connectors being suited to be mutually connected to each other. In the first connector, the electric terminals are movable with respect to the first terminal.
