NS-A5818B - Bernard NS-A5818B AccuLock S Brass Nozzle, 5/8 Inch Bore

Upgrade Your MIG Gun with Bernard AccuLock S Nozzles

Welders know that the front-end consumables of a MIG gun are the first line of defense against weld defects. The Bernard AccuLock S MIG Nozzle (NS-A5818B) is designed to keep you welding longer with fewer interruptions. If you are running a smaller Bernard BTB Series gun, this brass nozzle is the perfect fit for your setup, offering the reliability you expect from the Bernard brand.

Optimized Gas Coverage
With a 5/8-inch bore, this nozzle delivers excellent shielding gas coverage. Whether you are welding mild steel, stainless, or other alloys, maintaining a pure atmosphere around the weld pool is essential for preventing porosity. The 5/8-inch size is a versatile standard, large enough to handle higher gas flow rates required for spray transfer, yet compact enough to maneuver into standard joints.

Built for Durability
The solid brass construction of the NS-A5818B is tough enough to withstand the rigors of the shop floor. Brass nozzles are excellent at resisting spatter buildup, meaning you spend less time cleaning your nozzle and more time laying beads. The 1/8-inch tip recess is the "sweet spot" for many welders—it keeps your contact tip recessed just enough to prevent burnback and overheating, but close enough to maintain good electrical stick-out and arc control.

The AccuLock Advantage
Changing consumables shouldn't be a struggle. The AccuLock S system is designed for quick replacements and a secure fit. When your nozzle is locked on tight and centered perfectly, your wire feeds smoother and your arc stays right where you aim it. This 10-pack ensures you have fresh nozzles on hand whenever you need them, minimizing downtime and keeping your production moving.
