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

Technical Overview of the Bernard LAD3A-15 Liner

The Bernard LAD3A-15 is a specialized MIG gun liner engineered for the AccuLock™ S consumable system. Designed to meet the rigorous demands of industrial welding environments, this liner is compatible with Bernard BTB MIG guns. It is constructed as a heavy-duty monocoil, providing the structural integrity necessary to prevent collapsing or kinking inside the cable assembly, which is a primary cause of erratic wire feeding.

This specific model is calibrated for wire diameters ranging from 0.035 inches to 0.045 inches (0.9mm to 1.2mm), covering the most common range for general fabrication and manufacturing applications. With a total length of 15 feet (4.57 meters), it fits standard length gun cables, ensuring full coverage from the feeder to the contact tip. The AccuLock S system is designed to be error-proof, and the LAD3A-15 plays a pivotal role in this by ensuring the wire path is centered and smooth, minimizing friction and drag.

Proper liner selection and maintenance are critical for achieving high-quality welds. A worn or incorrect liner can lead to micro-arcing, burn-back, and unstable arcs. The LAD3A-15 is manufactured to precise tolerances to ensure optimal electrical conductivity and mechanical guidance of the welding wire. It is an essential component for maintaining the performance standards of Bernard MIG equipment.
