Welding aluminum can be a headache if you aren't using the right equipment. The soft nature of aluminum wire makes it prone to "bird-nesting" at the drive rolls or shaving inside the gun cable if it encounters any resistance. The Bernard 44215X Aluminum Liner is the solution to these common frustrations. Specifically engineered for 400 Amp Bernard MIG guns, this liner replaces the standard steel coil with a smooth, high-quality polymer tube. This material allows the wire to glide effortlessly from the feeder to the contact tip, eliminating the friction that causes feeding erraticism.
If you are running 3/64" or 1/16" aluminum wire, this is the liner you need. It comes ready to install at 15 feet in length but is easily customizable; simply lay it out next to your gun cable and trim the excess for a perfect fit. A well-fitted liner supports the wire along the entire path, preventing it from buckling under the pressure of the drive rolls. This is especially important when welding in out-of-position scenarios or when the cable is bent. Upgrading to a fresh 44215X liner can instantly improve your arc stability and weld bead appearance by ensuring a constant wire speed.
Don't let feed problems ruin your aluminum projects. Whether you are a professional fabricator or a serious hobbyist working on aluminum repairs, the difference a fresh polymer liner makes is night and day. This genuine Bernard part fits Q-Gun, S-Gun, and T-Gun models, restoring them to factory performance levels for aluminum applications. Keep a spare 44215X in your toolbox so you are always ready to switch over to aluminum or replace a dirty liner without halting your work. Experience smoother starts, fewer burnbacks, and cleaner welds with the right liner for the job.
