The Bernard NS-1218B is a high-performance MIG welding nozzle designed for the Centerfire™ consumable system. Engineered for professional fabrication environments, this nozzle features a 1/2-inch (12.7 mm) bore and positions the contact tip with a 1/8-inch (3.175 mm) recess. This specific recess depth helps protect the contact tip from excessive heat and spatter buildup while ensuring adequate gas coverage for the weld pool. Manufactured from durable brass, the NS-1218B is built to withstand the thermal stresses of medium to heavy-duty welding applications.
One of the standout features of the Centerfire system is the built-in spatter shield located within the nozzle. This component serves a dual purpose: it protects the gas diffuser from clogging with spatter and acts as a gas straightener. By smoothing the shielding gas flow, the nozzle reduces turbulence, which minimizes the risk of weld porosity and oxidation. The nozzle's threaded design secures the contact tip in a fixed position, ensuring a solid, concentric relationship that improves electrical conductivity and heat dissipation.
Designed for efficiency, the NS-1218B allows for "drop-in" contact tip replacement without the need for tools. This significantly reduces downtime during consumable changeovers. The nozzle is compatible with all standard air-cooled Bernard MIG guns, including the BTB (Best of the Best), S-Gun, W-Gun, and Clean Air series. It is also suitable for use with most competitive brand MIG guns that have been retrofitted with Bernard Centerfire front-end parts. This 10-pack configuration ensures your shop is stocked for continuous production.
