NT-A3800C - Bernard AccuLock S 3/8" Tapered Nozzle, Flush, 10-Pack

Precision and Reliability with Bernard AccuLock S Nozzles

The Bernard NT-A3800C is a premium 3/8-inch tapered nozzle designed for the revolutionary AccuLock S consumable system. Engineered to address the most common challenges in industrial MIG welding, these nozzles play a critical role in maintaining arc stability and wire feed consistency. By integrating seamlessly with AccuLock S contact tips and diffusers, the NT-A3800C ensures that the contact tip is perfectly centered and locked in position, reducing the risk of burn-backs and erratic arcs caused by loose components.

One of the standout features of this nozzle is its flush tip relationship. A flush nozzle is often preferred for short-circuit MIG welding or when working on thinner materials where stick-out length needs to be minimized for better control. The 3/8-inch bore combined with a tapered shape allows the welder to access tight corners and complex joint geometries that standard cylindrical nozzles cannot reach. This improved access comes without sacrificing gas coverage, thanks to the precise engineering of the gas flow path within the AccuLock S system.

Maintenance and troubleshooting are major cost drivers in any welding operation. The AccuLock S system, utilized by the NT-A3800C, is specifically designed to eliminate liner trim length errors—a frequent cause of wire feeding issues. By capturing the liner and keeping it concentric with the contact tip, these nozzles help prevent the friction and drag that lead to bird-nesting. This 10-pack configuration ensures that your shop is well-stocked with high-quality copper nozzles, minimizing downtime and keeping your production line moving efficiently.
