LAD3A-15` - Bernard LAD3A-15 AccuLock S Heavy Duty Liner .035-.045 15ft

Bernard LAD3A-15 AccuLock S Heavy Duty Liner Overview

The Bernard LAD3A-15 is a premium heavy-duty liner designed specifically for the AccuLock S consumable system, widely utilized in Bernard BTB (Best of the Best) MIG guns. Engineered to accommodate wire diameters from .035" to .045" (0.9mm to 1.2mm), this liner provides a robust solution for industrial welding environments where consistent wire feeding is critical. The liner measures 15 feet (4.57 meters) in length, making it suitable for standard length cable assemblies used in general fabrication and manufacturing.

As part of the AccuLock S system, this liner addresses common issues associated with liner replacement, such as incorrect trimming and gaps between the liner and the contact tip. The AccuLock S design ensures the liner is concentrically locked within the gas diffuser, minimizing gas turbulence and ensuring the wire is directed precisely into the contact tip. This heavy-duty variant is constructed from high-grade steel wound to precise tolerances, offering superior resistance to kinking and crushing compared to standard liners. This structural integrity is essential for maintaining a smooth wire path, particularly when the MIG gun cable is bent or manipulated during operation.

Installation of the LAD3A-15 follows Bernard's streamlined maintenance procedures. The liner is loaded from the back of the gun, and the AccuLock S system's unique interaction with the power pin and front-end consumables simplifies the trimming process. By maintaining a continuous and protected path for the welding wire, this liner significantly reduces friction and drag, which are primary causes of erratic arcs and burn-backs. It is an OEM replacement part, ensuring full compatibility and performance retention for Bernard welding systems.

Facilities managers and procurement specialists should note that this liner is specifically keyed for the AccuLock S system and may not be compatible with Centerfire or Quik Tip systems without the appropriate conversion parts. Its heavy-duty classification makes it the preferred choice for high-volume welding stations running solid steel or flux-cored wires within the specified diameter range.
