14411135 - Tweco 44N-116-15 Nylon MIG Gun Liner for 1/16" Aluminum Wire

Optimized Wire Feeding for Aluminum Applications

The Tweco 1441-1135 (Model 44N-116-15) is a specialized conduit liner designed to address the unique challenges of feeding soft welding wires, particularly aluminum. Unlike standard steel liners which can cause friction, shaving, and buckling (bird-nesting) when used with soft alloys, this liner is constructed from high-quality nylon. The low-friction coefficient of the nylon material ensures that 1/16-inch (1.6mm) aluminum wire glides smoothly through the MIG gun cable, maintaining consistent arc stability and wire feed speeds essential for high-quality aluminum welds.

This conduit is part of the Tweco 44 Series and measures 15 feet (4.6 meters) in length, making it suitable for standard length MIG gun assemblies commonly used in industrial fabrication. The liner is engineered to fit Tweco No. 4 and No. 5 series MIG guns, as well as other compatible systems requiring the 44 Series geometry. Its durable monofilament construction resists kinking while providing the necessary flexibility to maneuver the gun during complex welding operations. Proper liner selection is critical in aluminum MIG welding (GMAW), and the 44N-116-15 is the industry standard solution for 1/16" wire applications.

Installation of the 1441-1135 is straightforward, following standard Tweco maintenance procedures. The liner supports the wire from the drive rolls to the contact tip, minimizing unsupported length where buckling often occurs. By reducing drag and preventing contamination that can occur with steel liners, this nylon conduit extends the service life of your consumables and improves overall productivity by reducing downtime associated with feed failures.
