Universal conduit liner for a welding torch

A welding torch comprising:

• a welding gun handle;
• a welding cable defining a proximal end portion and a distal end portion, the welding cable secured to the welding gun handle at the distal end portion;
• a universal conduit assembly disposed at the proximal end portion of the welding cable, the universal conduit assembly comprising:
• a conduit liner included as part of the welding cable and further defining the proximal end portion and distal end portion;
• a conduit tip secured to the proximal end portion of the conduit liner;
• and
• an interchangeable conduit stop removably secured to the conduit tip, the interchangeable conduit stop adapted for connection to a specific OEM power connector, wherein the interchangeable conduit stop extends beyond a distal end of the conduit tip to partially cover an electrical insulator surrounding and positioned directly adjacent to the conduit liner.

A welding conduit kit comprising:

• a conduit liner defining a proximal end portion and a distal end portion;
• a conduit tip secured to the proximal end portion of the conduit liner;
• and
• a plurality of interchangeable conduit stops adapted for being removably secured to the conduit tip, the interchangeable conduit stops adapted for connection to specific OEM power connectors, wherein the interchangeable conduit stops extend beyond a distal end of the conduit tip to partially cover an electrical insulator surrounding and positioned directly adjacent to the conduit liner.

A universal conduit assembly for a welding torch comprising:

• a conduit liner defining a proximal end portion and a distal end portion;
• a conduit tip secured around the proximal end portion of the conduit liner, the conduit tip defining an externally threaded portion, a central bore extending from a proximal end portion to a distal end portion, and a chamfer disposed around the central bore at the distal end portion;
• and
• an interchangeable conduit stop defining an internally threaded portion for engagement with the externally threaded portion of the conduit tip, the interchangeable conduit stop adapted for connection to a specific OEM power connector, wherein the interchangeable conduit stop extends beyond a distal end of the conduit tip to partially cover an electrical insulator surrounding and positioned directly adjacent to the conduit liner, and
• wherein the proximal end portion of the conduit tip extends to a distal end portion of the conduit stop, and the conduit stop defines an internal shoulder and the conduit tip defines an external shoulder such that the external shoulder of the conduit tip abuts the internal shoulder of the conduit stop to provide a gas seal.

A conduit tip for use with a conduit liner of a welding torch, the conduit tip comprising:

• a body defining a proximal end portion and a distal end portion;
• an external attachment area for securing a variety of conduit stops;
• an internal recess for receiving a conduit liner;
• a central bore extending from the proximal end portion to the distal end portion;
• a chamfer disposed around the central bore at the proximal end portion;
• and
• an external shoulder adapted for engaging an internal shoulder of one of the variety of conduit stops to provide a gas seal, the one of the variety of conduit stops extending beyond a distal end of the conduit tip to partially cover an electrical insulator surrounding and positioned directly adjacent to the conduit liner.
