Ensure precision wire delivery in your push-pull MIG operations with the Miller 229674 FasTip Teflon Liner. Designed specifically for the demands of aluminum welding, this liner fits into the 6-inch head tube assemblies of FasTip-equipped MIG guns. The use of Teflon is non-negotiable when feeding soft alloys; it significantly reduces the coefficient of friction compared to steel or brass liners, allowing the wire to glide smoothly without galling or shaving.
This liner accommodates wire diameters ranging from .030 inches to .040 inches. It is a critical maintenance item for welders using Miller XR-Aluma-Pro, XR-Pistol-Pro, and other compatible push-pull systems. Over time, liners can become clogged with aluminum oxide dust or worn down by the wire, leading to erratic feeding and arc instability. Replacing your head tube liner regularly is a cost-effective way to maintain peak equipment performance.
The 229674 is a "short" liner, intended only for the curved neck section of the gun, not the entire cable assembly. This modular design allows you to replace just the high-wear neck section without discarding the main conduit liner. Trust genuine Miller components to provide the fit and durability required for industrial welding environments.
