OVERVIEW

Bernard Centerfire MIG Nozzle N-5818C

The Bernard N-5818C Centerfire MIG Nozzle is a premium consumable designed to enhance the performance and longevity of your Bernard MIG welding guns. Engineered with a 5/8-inch bore and a 1/8-inch recessed tip setting, this nozzle provides excellent gas coverage and arc visibility, making it a versatile choice for medium to heavy-duty welding applications. Constructed from high-quality copper, the N-5818C is built to withstand the intense heat and physical demands of industrial fabrication environments.

A key feature of this nozzle is its integral role in the Bernard Centerfire system. Unlike traditional nozzles that rely on threaded contact tips, the N-5818C secures a "drop-in" threadless contact tip. This design innovation eliminates the risk of cross-threading and allows welders to change tips by hand without tools, drastically reducing changeover time. The nozzle itself is threaded at the base to ensure a solid, concentric relationship with the head, keeping the contact tip perfectly centered for consistent electrical conductivity and arc stability.

Inside the nozzle, a built-in spatter shield serves a dual purpose. First, it acts as a barrier, protecting the gas diffuser and insulator from molten spatter, which extends the life of the front-end consumables. Second, it functions as a flow straightener, smoothing out the shielding gas turbulence to ensure a laminar flow over the weld pool. This results in reduced oxidation, less porosity, and a cleaner final weld. The N-5818C is compatible with all standard air-cooled Bernard Q-Gun, BTB, S-Gun, and Clean Air series MIG guns equipped with D-1 gas diffusers.
