NS-5818B - Bernard Centerfire Brass MIG Nozzle 5/8" Bore 1/8" Recess

Maximize Uptime with Bernard Centerfire Nozzles

Welders know that downtime kills productivity. The Bernard NS-5818B Centerfire MIG Nozzle is built to keep you welding longer with less hassle. Part of the revolutionary Centerfire system, this nozzle works in tandem with "drop-in" contact tips that require no tools to change. While the nozzle itself threads on securely to keep everything aligned, removing it to check your tip or clean out spatter is quick and easy.

Why choose the NS-5818B?

• Better Gas Coverage: The 5/8-inch bore combined with a 1/8-inch recess provides excellent shielding gas coverage, reducing porosity and rework.
• Built-in Protection: A specialized spatter shield inside the nozzle protects your gas diffuser from clogging, ensuring smooth, non-turbulent gas flow even in dirty welding environments.
• Durable Brass Body: Made in the USA, the solid brass construction resists heat buildup and stands up to the abuse of daily shop life.

Whether you are running a Bernard Q-Gun or have retrofitted your existing equipment with Centerfire consumables, this nozzle delivers the consistency you need. The tapered seat and large diameter base of the mating contact tips (sold separately) ensure that your arc stays stable and your consumables run cooler. Stop fighting with cross-threaded tips and clogged diffusers—switch to the reliability of the Bernard Centerfire NS-5818B.
