Keep your aluminum welding operations running smoothly with this 15-foot polymer MIG gun liner. Modeled after the standard Bernard 44215 specifications, this aftermarket replacement is built to handle 0.035" and 0.045" aluminum welding wires. If you are experiencing erratic feeding, burn-backs, or wire pile-ups at the feeder, a worn or incorrect liner is often the culprit. Switching to a fresh polymer liner is the most effective maintenance step for reliable aluminum welding.
This liner features a Miller-style back end pin, ensuring it locks correctly into Miller wire feeders and power sources. It is designed to fit 15-foot Bernard Q-Series, S-Series, and T-Series MIG guns. The durable outer insulation protects the inner polymer tube from kinking during installation, while the inner diameter is precision-extruded to support the wire without excessive drag.
Installation Tip: When installing polymer liners for aluminum, it is crucial to keep the gun cable straight. Insert the liner until the back end seats fully, then trim the front excess at the nozzle end according to your gun's specific stick-out requirements. A sharp liner cutter is recommended to ensure the polymer tube is not crushed during trimming.
