14501155 - Tweco 1450-1155 MIG Gun Liner 15ft .035-1/16 Wire

Reliable Wire Feeding with Tweco 1450-1155 Conduit

The Tweco 1450-1155 Standard Conduit Liner is a critical component for maintaining peak performance in your MIG welding operations. Designed by ESAB under the renowned Tweco brand, this liner is engineered to guide welding wire from the wire feeder through the gun cable to the contact tip with minimal friction and resistance. A smooth wire feed path is essential for establishing a stable arc, reducing spatter, and preventing costly downtime caused by wire jams or "bird-nesting" at the drive rolls.

This specific liner belongs to the 44 Series and is optimized for use with hard steel wires ranging from .035 inches to 1/16 inches (0.9mm to 1.6mm). Its 15-foot (4.5-meter) length makes it suitable for standard length MIG gun assemblies, providing ample reach for most fabrication and shop environments. The liner is constructed from high-quality zinc-plated spring steel, which offers excellent flexibility while maintaining the rigidity necessary to prevent kinking inside the cable. The zinc plating also provides corrosion resistance, ensuring the liner remains smooth and clean over its service life.

Replacing your conduit liner regularly is one of the most effective ways to troubleshoot erratic wire feeding. Over time, liners can become clogged with copper shavings, dirt, and debris, or they can develop kinks that restrict wire movement. The Tweco 1450-1155 is a direct replacement for worn-out liners in Tweco Spray Master, Classic Number Series, and other compatible MIG guns. Installation is straightforward, requiring only basic tools to trim the liner to the correct stick-out length for your specific gun model.

Whether you are welding in a heavy industrial setting, an automotive repair shop, or a general fabrication facility, trusting genuine Tweco consumables ensures your equipment operates as intended. This liner delivers the consistency professional welders demand, helping you achieve high-quality welds with every pull of the trigger.
