M1365 - Miller M1365 Teflon Jump Liner .047-.062 for Fastip

Precision Aluminum Feeding with Miller M1365

The Miller M1365 Liner is a specialized component designed to optimize the performance of your MIG welding setup, specifically when working with soft alloys like aluminum. This liner is constructed from high-quality Teflon, a material renowned for its exceptionally low coefficient of friction. Unlike steel liners, which can abrade soft aluminum wire and cause shavings to clog the conduit, this Teflon liner ensures a smooth, uninterrupted glide path for the filler metal. It is engineered to accommodate wire diameters ranging from .047 inches (approximately 3/64") to .062 inches (1/16"), covering the most common sizes used in industrial aluminum fabrication.

Measuring 6 inches in length, the M1365 is typically utilized as a jump liner or neck liner within the welding gun assembly, particularly in systems utilizing Fastip consumables. The neck of a MIG gun is often where the most severe bending occurs, creating friction points that can lead to feeding resistance. By installing a dedicated Teflon liner in this section, you maintain the integrity of the wire right up to the contact tip. This is crucial for preventing "bird-nesting" at the drive rolls and ensuring a stable arc, which is notoriously difficult to maintain with aluminum welding.

Genuine Miller parts like the M1365 are manufactured to strict tolerances to ensure perfect compatibility with your equipment. Using OEM replacements guarantees that the liner fits securely within the gun neck, preventing gas leakage or electrical conductivity issues. Whether you are operating a push-pull gun or a standard MIG gun setup adapted for aluminum, maintaining fresh liners is a key maintenance practice. Over time, even Teflon liners can wear or accumulate debris; replacing them regularly with the M1365 helps maintain high productivity and weld quality in demanding production environments.
