The Bernard 44215X is a 15-foot polymer (Teflon) liner designed for 400A MIG guns, specifically engineered for feeding 3/64" to 1/16" aluminum wire. It serves as a low-friction conduit to replace standard steel liners, preventing wire shaving and feeding issues such as bird-nesting in industrial welding applications.
Features
Low-friction polymer construction reduces wire drag and resistance
Eliminates aluminum wire shaving common with steel coil liners
Prevents bird-nesting at the drive rolls
Trimmable design allows for custom fit to specific MIG gun cable lengths
Supports wire along the entire path to prevent buckling under drive roll pressure
