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

Bernard Centerfire Nozzle N-3418B - Brass 3/4" Orifice

Optimize your MIG welding setup with the Bernard N-3418B Centerfire Nozzle, a high-performance brass component designed for the modern welder. This nozzle is a staple in the Bernard Centerfire consumable family, known for delivering superior arc stability and gas coverage. With a generous 3/4-inch orifice, the N-3418B is specifically tailored for applications that demand high gas flow rates, typically associated with higher amperage welding on thicker materials. The 1/8-inch recess places the contact tip slightly back inside the nozzle, offering excellent protection against burn-back and reducing the frequency of tip replacements caused by short circuits or spatter accumulation.

Threadless Efficiency

One of the standout features of the N-3418B is its threadless, drop-in installation method. Unlike traditional nozzles that require screwing on and off—often seizing up due to heat and spatter—the Centerfire nozzle slides over the diffuser and locks into place with a simple twist of the spatter shield. This innovation means you can swap out nozzles in seconds, even with gloved hands, keeping your arc-on time maximized. The integrated spatter shield also serves to align the contact tip perfectly within the nozzle, guaranteeing a concentric gas shield that minimizes porosity and weld defects.

Brass Construction for Heavy Duty Use

While copper is standard for many nozzles, the brass construction of the N-3418B (indicated by the 'B' in the part number) provides a robust alternative that excels in specific high-heat environments. Brass is tough and often allows spatter to be removed more easily, maintaining a clear gas path for longer periods. This 10-pack of nozzles ensures that you have a reliable supply of consumables ready for your Bernard BTB, Q-Gun, or S-Gun MIG torches. Whether you are welding mild steel, stainless, or aluminum, the consistent performance of the Bernard Centerfire system helps you achieve high-quality welds with less hassle.
