The XTRWELD 136683 is a MIG liner wire conduit designed for Miller-style MIG welding guns. It fits wire sizes from 0.045 inches up to 0.0625 inches (1/16 inch) and measures 6.75 inches in length. This liner guides the welding wire through the gun cable, reducing friction and preventing feed problems during operation. It is manufactured to OEM-equivalent quality standards, making it a direct interchange replacement for Miller-style consumables. Welding professionals and fabrication technicians will find this liner to be a straightforward drop-in service part for maintaining consistent wire feed performance.
This liner is suited for use with Miller XRa, XRMa, and Spoolmatic series MIG welding guns. It is appropriate for both shop and field welding applications where Miller-style consumables are specified. The part number and size are marked directly on the product for quick identification during inventory management or mid-job replacement. Each unit is sold individually, making it easy to stock as a single replacement or in quantity for high-volume operations.
Designed as an OEM-style replacement liner for Miller XRa, XRMa, and Spoolmatic series MIG welding guns accepting 0.045 inch to 0.0625 inch wire. Brand names referenced are for identification purposes only.
MIG liner replacement should be performed by a qualified welding technician with the machine powered down and the wire feed de-energized before beginning service. Remove the existing liner from the gun cable, feed the new liner through from the drive end, and trim to length if required before securing the gun neck. Inspect the liner ends for burrs that could cause wire hang-up during feed. Follow the gun manufacturer's assembly instructions and applicable welding safety standards during installation.
