The XTRWELD 44-116-25 is a 25-foot MIG wire conduit liner sized for 1/16-inch wire, built to OEM quality standards for use with Tweco-style MIG guns. The liner guides the welding wire from the drive roll through the gun cable to the contact tip, maintaining consistent wire feed and reducing bird-nesting during operation. Proper liner sizing is critical to stable arc performance and reduced drive motor wear. This liner is sold individually and is designed for professional welders working with mid- to high-amperage MIG applications in fabrication shops, maintenance environments, and production welding settings.
This liner is compatible with Tweco-style MIG guns rated from 300 amps to 450 amps, including the Classic, Eliminator, Weldskill, Spray Master, PulseMaster, Smoke Master, and Velocity series guns. It is intended for use with 1/16-inch welding wire and fits the standard conduit housing used across the Tweco-style platform. The 25-foot length suits standard gun cable assemblies commonly found in industrial and shop welding setups.
Compatible with Tweco-style MIG guns rated 300 amps to 450 amps, including the Classic, Eliminator, Weldskill, Spray Master, PulseMaster, Smoke Master, and Velocity series. Interchangeable with Tweco Weldskill consumables. Brand names referenced are for fitment identification only.
MIG liner replacement is a standard maintenance task performed by welders and welding equipment technicians. Before replacing the liner, power down the welder and release all wire tension from the drive rolls. The liner should be trimmed to the correct length per the gun manufacturer's specification before inserting and securing it in the gun body. Avoid kinking the liner during installation, as bends will cause wire feed resistance and premature wear.
