Xtrweld 45-40-15 Mig Liner 0.040 Inch 15 Ft Tweco Style

Product Description

The XTRWELD 45-40-15 is a MIG liner wire conduit designed to guide welding wire smoothly through a MIG gun cable assembly. Sized at 0.040 inches in diameter and 15 feet in length, this liner fits Tweco-style MIG guns and delivers consistent wire feed performance in production and fabrication environments. OEM-quality construction keeps wire feeding reliably with minimal friction and wear. Welders, fabricators, and maintenance technicians install this liner as a direct replacement when feed problems or conduit wear are detected.

This liner is designed for use with Tweco-style MIG guns rated from 100 amps to 160 amps, including Classic, Weldskill, Velocity, and Mini-MIG configurations. It suits light to medium-duty welding applications common in fabrication shops, maintenance facilities, and light industrial settings where Tweco-style consumables are standard. Each unit is marked with the part number or size for quick identification during changeout.

Installation Notes

MIG liner replacement is performed by qualified welders or maintenance technicians. Before servicing, disconnect the MIG gun from the welder and relieve any wire tension from the drive roll assembly. Thread the new liner carefully through the cable assembly to avoid kinking, and trim to length if required before securing the neck and diffuser. Follow the equipment manufacturer's guidelines for liner installation and torch reassembly.
