The Tweco 1440-1115 (Model 44-116-25) is a premium steel conduit liner designed for heavy-duty industrial MIG welding applications. Engineered by Tweco, a leader in arc welding accessories, this liner is part of the standard 44 Series, known for its reliability and compatibility with a broad range of professional MIG guns. It is specifically wound to handle 1\/16-inch (1.6mm) welding wire, providing the necessary support and low-friction path required for consistent wire delivery.<\/p>\n
With a total length of 25 feet (7.6 meters), this liner is ideal for extended-reach setups where the wire feeder is positioned at a distance from the workpiece. The liner is constructed from high-quality zinc-plated spring wire, which offers excellent resistance to corrosion and wear, ensuring a long service life even in harsh shop environments. The zinc plating also acts as a dry lubricant, further reducing drag on the welding wire.<\/p>\n
This component is a direct replacement for liners in Tweco Spray Master series guns (MS250, MS350, MS450) and Tweco Classic No. 3, No. 4, No. 5, and No. 6 MIG guns equipped with 25-foot cables. Proper maintenance of the conduit liner is critical for preventing wire feeding issues such as bird-nesting, erratic arc, and burn-back. Installing the correct OEM liner guarantees that your equipment operates at peak performance specifications.<\/p>\n
The 44-116-25 liner features a standard outer diameter compatible with the gas diffusers and power pins found in the specified Tweco gun models. Installation is straightforward: simply remove the old liner, insert the new conduit, and trim the excess length at the front end according to the manufacturer’s instructions for your specific gun model. This ensures the liner sits flush against the gas diffuser or contact tip, preventing gas leakage and wire shaving.<\/p>\n","protected":false},"excerpt":{"rendered":"Genuine Tweco 44-116-25 Conduit Liner The Tweco 1440-1115 (Model 44-116-25) is a premium steel conduit liner designed for heavy-duty industrial MIG welding applications.
