44215X - Bernard 44215X Aluminum MIG Liner 15ft 3/64-1/16

Genuine Bernard 44215X Aluminum Liner for Industrial MIG Systems

The Bernard 44215X Liner is a critical component for industrial welding operations utilizing aluminum wire. Designed specifically for Bernard MIG guns rated at 400 Amps, this liner ensures the consistent and reliable delivery of soft aluminum filler metals. Unlike standard steel liners, which can cause friction and shaving of aluminum wire, the 44215X features a specialized polymer construction (often referred to as Teflon or plastic) that significantly reduces drag. This low-friction environment is essential for maintaining a stable arc and preventing feed issues that lead to costly downtime.

This assembly comes in a standard 15-foot length, making it suitable for most standard MIG gun cables. It is designed to accommodate wire diameters ranging from 3/64 inch to 1/16 inch, covering the most common sizes used in heavy fabrication and manufacturing. For facilities using shorter gun cables, the liner can be easily trimmed to the precise length required during installation. Proper liner maintenance is vital for aluminum welding; a worn or clogged liner is a leading cause of erratic feeding and burnback. By choosing the genuine Bernard 44215X, you ensure compatibility with your Q-Gun, S-Gun, or T-Gun system and maintain the high-performance standards expected from Bernard equipment.

Industrial MRO managers and welding supervisors trust Bernard consumables for their durability and precision. This liner is part of the 44 Series, a standard in the industry for heavy-duty applications. Whether you are fabricating trailers, boat hulls, or structural aluminum components, ensuring your MIG guns are equipped with the correct polymer liner is the first step toward defect-free welds. The 44215X provides the smooth conduit necessary to push soft aluminum wire over distance without buckling, ensuring your production line keeps moving efficiently.
