14201123 - Tweco 1420-1123 .045 MIG Gun Liner for Rebel Series - 15 ft

Product Overview

The Tweco 1420-1123 Replacement Liner is a critical maintenance component designed to restore the performance of MIG welding systems, specifically those utilizing the Rebel Series and Fusion 180 MIG guns. Engineered to precise tolerances, this liner is optimized for use with .045-inch (1.2 mm) diameter welding wire, ensuring that the consumable travels smoothly from the wire feeder to the contact tip without interruption or excessive drag.

Manufactured from high-grade steel, the conduit features a wound construction that provides the necessary flexibility for maneuvering the gun while maintaining sufficient rigidity to prevent kinking. With a length of 15 feet, it is suitable for standard gun assemblies used in a variety of fabrication environments. Regular replacement of the liner is essential for preventing common feeding issues such as bird-nesting, erratic wire speeds, and unstable arcs, which can compromise weld quality and increase downtime.

This genuine Tweco part ensures full compatibility with the backend and frontend geometry of ESAB Rebel and Fusion 180 equipment. By maintaining the integrity of the wire path, the 1420-1123 liner supports consistent electrical conductivity and shielding gas flow, contributing to the overall efficiency of the welding operation. It is an indispensable spare part for facilities relying on Rebel Series welders for mild steel and general fabrication applications.
