OVERVIEW

Restore Precision to Your MIG Welding

As a welder, you know that a stable arc starts with smooth wire delivery. If you are experiencing stuttering wire, burn-backs, or the dreaded "birdnesting" at the drive rolls, the culprit is often a worn or dirty gun liner. The Miller 194405 Conduit/Liner is the direct replacement you need to restore the buttery-smooth performance of your MIG gun. Designed specifically for 15-foot cable assemblies, this liner is optimized for running .035" and .045" welding wires, covering the vast majority of structural and general fabrication applications.

The construction of this liner features a high-quality steel monocoil design. This spiral steel structure provides the necessary flexibility to maneuver the gun around complex weldments while maintaining a rigid enough internal channel to prevent the wire from buckling. Unlike plastic or Teflon liners used for aluminum, this steel liner is built to handle the abrasion of mild steel, stainless steel, and flux-cored wires. It effectively reduces friction inside the cable, allowing your wire feeder to operate with less strain and providing you with consistent stick-out and arc control.

Installation is straightforward, as the liner comes with the correct fittings for Miller guns. When trimming the liner to fit, remember to follow the manufacturer's guidelines for your specific gun model to ensure the correct stick-out length at the diffuser. A liner that is cut too short can cause gas flow issues and micro-arcing inside the diffuser, while one that is too long can cause kinking. With the Miller 194405, you start with a premium quality base that ensures your cut and fit will result in superior performance.

Don't let a cheap consumable compromise your weld quality. A fresh liner is one of the most cost-effective ways to improve your welding experience immediately. Replace your old, kinked, or clogged liner with this genuine Miller part and get back to laying down perfect beads with confidence.

FAQ

This liner is designed for wire diameters ranging from 0.035 inches to 0.045 inches.

The liner is 15 feet long, making it suitable for 15-foot MIG gun cable assemblies. It may need to be trimmed for shorter guns, but it is primarily intended for 15-foot setups.

No, this is a steel monocoil liner intended for hard wires like mild steel or stainless steel. For aluminum welding, you should use a nylon or Teflon liner to prevent wire shaving and friction.

Liners should be replaced whenever you experience erratic feeding that cannot be solved by changing contact tips or adjusting drive rolls. In heavy production environments, this could be monthly; for intermittent use, it may be once or twice a year.

Yes, the Miller 194405 comes as a conduit/liner assembly with the necessary fittings attached or included for installation.

Using a liner with an internal diameter that is too large for the wire (e.g., running .023 wire in this .045 liner) can cause the wire to snake or buckle inside the liner, leading to erratic feeding and an unstable arc.

Yes, this is a genuine Miller Electric replacement part, ensuring proper fit and material quality for your Miller equipment.

Install the liner into the gun and seat it fully at the back end. Lay the gun cable out straight. At the front of the gun, mark the liner according to your gun manual's specifications (usually flush with the gas diffuser or sticking out slightly) and cut it using sharp wire cutters or a liner cutter, then file the end smooth.
