Welders know that aluminum is one of the most difficult materials to feed through a MIG gun. Its softness makes it prone to kinking, buckling, and dragging against the liner wall. The Tweco 44N-3545-15 Nylon Conduit Liner is the solution to these common frustrations. Specifically designed for use with aluminum wire, this 15-foot liner features a smooth nylon core that allows the wire to glide effortlessly from the feeder to the contact tip. By reducing drag, it helps maintain a constant wire feed speed, which is critical for achieving high-quality, porosity-free aluminum welds.
This liner is built to handle the heat and demands of industrial environments, supporting amperage ranges from 300A to 450A. It is compatible with wire sizes .030" through 3/64", making it a versatile choice for various aluminum MIG applications. The external structure is composed of galvanized spring wire, providing the necessary rigidity and crush resistance to protect the nylon core and the welding wire inside. It is a direct fit for Tweco Spray Master (MS350, MS450) and Eliminator (ELC250, ELC350, ELC450) MIG guns, as well as Professional Choice #3 and #4 series.
Maintenance is a breeze with the Tweco 44N-3545-15. The back end features a robust brass alloy stop that locks the liner in place, preventing it from walking or retracting during use. The part number is clearly stamped on this brass fitting, so you never have to guess if you have the right part in your hand. Upgrade your MIG gun setup with this premium nylon liner and experience the difference in feedability and arc stability on your next aluminum project.
