NS-1218B - Bernard NS-1218B Centerfire Nozzle, 1/2" Bore, 1/8" Recess, Brass (10-Pack)

Bernard Centerfire NS-1218B MIG Nozzle

Maximize your welding productivity with the Bernard NS-1218B Centerfire™ Nozzle. This premium brass nozzle is a staple in the welding industry, known for its rugged reliability and ease of use. Part of the renowned Centerfire consumable series, the NS-1218B is designed to eliminate the frustrations associated with traditional screw-on nozzles and contact tips. With its unique design, no tools are required to replace the nozzle or the contact tip, allowing welders to make quick changes on the fly and get back to the arc faster.

The NS-1218B features a "Small Standard" body profile with a 1/2-inch bore, making it versatile enough for a wide range of joint configurations. The 1/8-inch tip recess is ideal for general-purpose MIG welding, providing a protective setback for the contact tip while maintaining excellent visibility of the puddle. Inside the nozzle, a ceramic insulator and a built-in spatter shield work together to extend the life of the consumable. The spatter shield directs the shielding gas evenly, reducing turbulence and ensuring a clean, contaminant-free weld deposit.

This nozzle is engineered to fit all standard air-cooled Bernard MIG guns, including the popular BTB Semi-Automatic guns and the legacy Q-Gun and S-Gun series. The threaded base of the nozzle holds the contact tip firmly in place, guaranteeing that the tip remains centered even after hard use. This concentric alignment is critical for maintaining consistent arc characteristics and preventing burn-backs. Whether you are welding mild steel, stainless steel, or aluminum, the Bernard NS-1218B delivers the performance and durability professional welders demand.

Benefits for the Welder:

• Tool-Free Maintenance: Swap nozzles and tips by hand in seconds.
• Consistent Quality: Fixed tip positioning prevents variations in stick-out.
• Enhanced Durability: Heavy-duty wall thickness and high-temperature insulator.
• Versatile Fit: Compatible with a vast array of Bernard and retrofitted guns.
