The Tweco 44N-3545-15 Conduit Liner is a specialized replacement part designed to master the challenges of feeding aluminum MIG wire. Unlike standard steel liners which can cause friction and shaving on soft alloys, this liner features a durable nylon interior surface housed within a galvanized spring wire conduit. This construction ensures a low-friction path that protects the integrity of soft aluminum wires (such as 4043 or 5356 grades), significantly reducing the risk of bird-nesting at the drive rolls and ensuring smooth, consistent arc performance.
Engineered for versatility and durability, this 15-foot liner is rated for high-amperage applications ranging from 300 to 450 amps. It is precision-manufactured to fit a wide range of industry-standard MIG guns, including the Professional Choice Series #3 and #4, the popular Spray Master MS350 and MS450, and the Eliminator Style ELC250, ELC350, and ELC450 models. The liner accommodates wire diameters from .030 inches up to 3/64 inches, covering the most common sizes used in aluminum fabrication.
Installation and identification are simplified thanks to the machined brass alloy stop located at the back end of the conduit. This stop ensures the liner seats correctly within the gun assembly for optimal gas flow and wire alignment. Additionally, the part number is roll-stamped directly onto the brass surface, allowing for quick verification and easy reordering when maintenance is required. Whether you are fabricating aluminum trailers, signage, or automotive components, the Tweco 44N-3545-15 provides the reliability professional welders demand.
