415-35-2 - Tregaskiss 15ft Aluminum Liner .035-.045 Steel Wrapped Nylon

Precision Engineering for Aluminum Welding

The Tregaskiss 415-35-2 Liner is a specialized component engineered to address the unique challenges of feeding aluminum welding wire. Unlike standard steel liners which can cause friction and shaving on soft aluminum alloys, or pure nylon liners which may lack the necessary rigidity for longer cable runs, this product utilizes a hybrid construction. It features a durable nylon core wrapped in high carbon music wire. This design provides a smooth, low-friction internal path that protects the integrity of the soft aluminum wire surface while the steel outer wrap ensures the liner maintains its shape and columnar strength inside the MIG gun cable.

Designed for use with wire diameters ranging from 0.035 inches to 0.045 inches, this 15-foot liner is compatible with standard Tregaskiss MIG welding guns. The precise internal tolerances reduce the gap between the wire and the liner wall, minimizing the opportunity for the wire to buckle or fold, a common issue known as bird-nesting. The high-carbon steel wrapping not only adds structural integrity but also extends the service life of the liner by protecting the polymer core from crushing forces and kinks during operation.

Proper liner selection is critical for maintaining arc stability and weld quality in aluminum applications. The 415-35-2 ensures consistent wire feed speeds by eliminating drag, which is essential for the spray transfer mode typically used in aluminum MIG welding. This component is an essential upgrade or replacement for industrial environments where aluminum fabrication requires high uptime and minimal equipment troubleshooting.

Installation of the liner follows standard Tregaskiss procedures, requiring proper trimming to ensure the liner seats correctly against the gas diffuser or retaining head. By using genuine Tregaskiss consumables, operators ensure that their equipment meets the manufacturer's specifications for performance and safety.
