ABSTRACT:
A gas-shielded arc-welding torch constituted by a holder section having a barrel adapted to retain a tungsten electrode and a handle section which supplies electric current to the holder section as well as an inert gas thereto, the holder section being bendable relative to the handle to assume any desired angular working position. Included in the handle section is a conductive metal helix of solid wire, one end of which is connected by a tubular metal coupler to the barrel of the holder section, the other end being connected by a pipe to a hollow electrical connector to define a current-supply line extending from the connector to the barrel. The coupler, the helix and the pipe are embedded in a torch body formed of elastomeric material, the body having a bore therein passing through the helix to join the pipe to the coupler and thereby define a gas supply conduit extending from the connector to the coupler which in turn communicates with the interior of the barrel to feed the gas into the region surrounding the electrode. The lower portion of the torch body and the connector are inserted within a handle, whereas the upper portion of the body which surrounds the upper portion of the helix is of reduced diameter to form therewith a flexible neck which permits bending of the holder section relative to the handle.
