Abstract
A welding torch includes a head (3) having a body (11) bearing an electrode (13); an electric power source (27); and a filler metal wire (17) and a wire guide (19) guiding the filler metal wire (17) to the electrode (13). The body (11) is obtained by additive manufacturing from an electrically conductive metal, and the electrode (13) is electrically connected to the electric power source (27) by the metal constituting the body (11). The wire guide (19) includes an insulating sheath (29) inside which the filler metal wire (17) moves, and the filler metal wire (17) is electrically insulated from the potential of the body (11) by the insulating sheath (29).

A welding torch comprising:
- a head having a body bearing an electrode;
- a power supply having an electric power source;
- and
- a filler metal wire and a wire guide guiding the filler metal wire to the electrode,
- the body being obtained by additive manufacturing from an electrically conductive metal, the electrode being electrically connected to the electric power source by the electrically conductive metal constituting the body, the wire guide comprising an insulating sheath inside which the filler metal wire moves, the filler metal wire being electrically insulated from a potential of the body by the insulating sheath;
- and
- a carrier integral with the head, the carrier being obtained by additive manufacturing from an electrically conductive metal, the electrode being electrically connected to the electric power source through the metal constituting the carrier, the filler metal wire being electrically insulated from the potential of the carrier by the insulating sheath.
