The Tweco 44N-116-15 Conduit (Part No. 1440-1012) is a specialized nylon liner designed to facilitate the smooth feeding of soft welding wires, particularly aluminum. Unlike standard steel liners which can cause friction, shaving, and bird-nesting when used with aluminum, this conduit features a low-friction nylon/teflon core. It is engineered to fit Tweco No. 3 and No. 4 series MIG guns, as well as compatible systems like certain Lincoln Magnum 300/400 assemblies that utilize Tweco-style consumables.
This liner is rated for wire diameters ranging from 0.045 inches to 1/16 inches (1.2mm - 1.6mm) and comes in a standard 15-foot length. The use of a polymer-based liner is critical in industrial aluminum fabrication to maintain consistent arc stability and wire feed speed. The 44N series conduit replaces the traditional steel wound liner, ensuring that the soft aluminum wire slides effortlessly from the feeder to the contact tip without snagging or deforming.
Installation of the 44N-116-15 is straightforward for maintenance personnel familiar with Tweco torch assemblies. The liner includes the necessary backend fittings to seat correctly in the power pin, ensuring proper gas flow and wire alignment. By reducing drag coefficient within the cable assembly, this product significantly extends the service life of consumables and reduces downtime associated with wire feed issues.
