N-3418B - Bernard Centerfire Brass Nozzle 3/4 Inch Orifice 1/8 Recess (10-Pack)

Bernard N-3418B Centerfire Brass Nozzle

The Bernard N-3418B Centerfire Nozzle is a premium consumable designed for professional MIG welding applications requiring robust performance and ease of use. Manufactured from high-quality brass, this nozzle is engineered to withstand the rigors of industrial environments while maintaining optimal gas shielding. The N-3418B features a large 3/4-inch orifice, making it ideal for high-amperage welding where substantial gas flow is necessary to protect the weld pool from atmospheric contamination. The 1/8-inch tip recess provides a critical balance between contact tip protection and arc visibility, ensuring that the tip remains shielded from excessive heat and spatter while allowing the operator to maintain precise control over the weld bead.

Centerfire System Technology

As part of the renowned Bernard Centerfire system, this nozzle integrates seamlessly with Centerfire gas diffusers and contact tips. The system is famous for its "drop-in" threadless design, which eliminates the frustration of cross-threading and allows for rapid changeovers without the need for tools. The nozzle is held firmly in place by the spatter shield, which also acts to center the contact tip, ensuring consistent electrical conductivity and gas flow concentricity. This design philosophy not only improves weld quality but also significantly reduces downtime associated with consumable maintenance.

Durability and Performance

The choice of brass for the N-3418B model offers specific benefits in thermal management and spatter resistance. In many heavy-duty applications, brass nozzles resist the adhesion of molten spatter better than standard copper counterparts, making them easier to clean and extending their service life. The built-in spatter shield further enhances longevity by preventing debris from clogging the gas diffuser ports. Whether used in structural steel fabrication, heavy equipment manufacturing, or general industrial welding, the Bernard N-3418B delivers the reliability that professional welders demand. This product is sold in a convenient package of 10, ensuring your shop is stocked for continuous operation.
