N-5800C - Bernard Centerfire 5/8" Flush Copper Nozzle for Q-Guns

Bernard Centerfire N-5800C: Smoother Flow, Less Downtime

Take the hassle out of your MIG gun maintenance with the Bernard N-5800C Centerfire MIG Nozzle. If you are tired of struggling with cross-threaded tips or inconsistent gas coverage, the Centerfire system is the upgrade you need. This specific nozzle, the N-5800C, offers a versatile 5/8-inch bore with a flush tip alignment, giving you the perfect balance of gas coverage and stick-out control for most general welding positions.

The beauty of this nozzle lies in its user-friendly design. It features a tapered seat and a large diameter base that provides exceptional electrical conductivity and heat transfer. This means your consumables run cooler and last longer, even under abuse. The nozzle threads on by hand—no tools required—and automatically centers your contact tip. Because the Centerfire tips are threadless and "drop-in," you can swap them out in seconds after a burnback without ever reaching for pliers. This keeps you under the hood welding, rather than fighting with your torch.

Inside the nozzle, a built-in spatter shield acts as a gas straightener. This ensures a laminar, non-turbulent flow of shielding gas over your weld puddle, reducing porosity and improving bead appearance. The solid copper construction is tough enough to withstand the heat of high-amperage welding while resisting spatter adhesion. Whether you are running a Bernard Q-Gun in a production line or a custom fab shop, the N-5800C nozzle delivers the consistency and ease of use that professional welders demand.
