The Tweco Style 44-116-15 MIG Gun Liner is a premium aftermarket replacement component designed to restore the performance of your MIG welding assembly. Engineered to meet the rigorous demands of industrial fabrication, this conduit liner is compatible with a broad range of widely used MIG guns, including the Tweco Professional Choice No. 3 and No. 4, the Spray Master MS350 and MS450, and the Eliminator EL250, EL350, and EL450 series. Its precise manufacturing ensures seamless integration with existing equipment, providing a cost-effective solution for maintenance and repair operations.
This liner is manufactured from high-grade spring wire that has been zinc-plated. The zinc plating serves a dual purpose: it significantly enhances corrosion resistance, protecting the liner from environmental factors during storage and use, and it provides a smoother surface finish. This reduction in surface friction is critical for minimizing drag on the welding wire, ensuring consistent wire feeding speeds and reducing the load on the wire feeder motor. The liner is wound to a tight tolerance to support 1/16-inch (1.6mm) diameter wires without allowing excessive play that could lead to micro-arcing or erratic arc characteristics.
At the back end of the liner, a machined brass alloy stop is permanently crimped onto the conduit. This brass stop is essential for proper seating within the power pin or gun block, ensuring a gas-tight seal and optimal electrical conductivity where required. The brass material is chosen for its durability and resistance to deformation under thermal stress. For ease of inventory management and part verification, the part number is roll-stamped directly onto the outside surface of the brass stop, allowing for quick identification even when the liner is removed from its packaging.
With a total length of 15 feet, this liner is sized for standard 15-foot MIG gun cable assemblies. It is specifically designed to handle the rigidity and feed characteristics of 1/16-inch welding wires, making it suitable for heavy-structural steel welding and other high-amperage applications. By maintaining the integrity of the wire path, the 44-116-15 liner helps prevent common feeding issues such as bird-nesting and wire chatter, thereby contributing to higher weld quality and reduced downtime.
