P44225 - Bernard Style 44225 MIG Liner .045-1/16 25ft

Precision Wire Delivery for Industrial Welding

The Bernard Style 44225 Liner Assembly is a critical component designed to restore and maintain the performance of your MIG welding operations. Engineered to meet the rigorous demands of industrial fabrication, this replacement liner is fully compatible with Bernard Q-Gun, S-Gun, and T-Gun series, as well as other MIG guns utilizing the EZ Feed system. It is specifically wound to accommodate wire diameters from .045 inches to 1/16 inches (1.2mm to 1.6mm), making it a versatile choice for structural steel, heavy equipment manufacturing, and general fabrication tasks.

Wire feeding issues are among the most common causes of downtime in automated and semi-automated welding. A compromised liner—whether clogged with debris, kinked, or worn from abrasion—can lead to erratic arc stability, bird-nesting at the drive rolls, and increased contact tip wear. This 44225-style liner features a high-tensile steel coil construction that provides the necessary rigidity to prevent collapsing while maintaining the flexibility required for maneuvering the gun cable. The internal surface is finished to minimize friction, ensuring a consistent wire feed speed even when the cable is looped or bent.

With a total length of 25 feet, this liner is intended for extended-reach gun assemblies but serves as a universal solution for shorter guns as well; it can be easily measured and trimmed to fit 10-foot, 12-foot, or 15-foot cables. This "trim-to-fit" capability allows inventory consolidation, reducing the need to stock multiple liner lengths for different gun models. Whether running solid mild steel wire or flux-cored wires, this liner ensures the electrode is delivered to the contact tip with precision and reliability.

Installation follows standard rear-loading procedures. The liner includes the necessary backend fitting (collet or stop) compatible with Bernard-style power pins. Regular inspection and replacement of the liner are recommended as part of a preventative maintenance schedule to ensure optimal weld quality and equipment longevity.
