Bernard Centerfire Nozzle 1/8" Recess

The Bernard NS-5818C is a copper welding nozzle with a 1/8 inch recess designed for Centerfire series guns. It fits Bernard and Miller compatible torches including BTB, Clean Air, Dura-Flux, FILTAIR, Q-Gun, S-Gun, XR-Aluma-Pro and XR-Pistol models. Welders replacing worn tips on these specific gun lines will find the correct thread and insulator geometry here.

Copper Construction Practical Limits

Copper conducts heat efficiently but erodes faster than plated or composite alternatives under high amperage or prolonged duty cycles. The 1/8 inch recess fixes the contact-tip-to-work distance which limits fine tuning for different joint designs or wire stick-out preferences. Spatter adhesion increases as the bore wears so frequent inspection is required to maintain gas coverage.

Upgrade From Worn Or Generic Tips

This nozzle replaces a deformed, pitted or ill-fitting tip that causes porosity, irregular bead shape or excessive spatter. The jump is worth it when the current tip no longer seats squarely on the diffuser or when the bore diameter has widened beyond spec. It is not for guns outside the listed Centerfire compatible series or for applications requiring adjustable recess lengths.

Questions about this item

Which Bernard Centerfire nozzle recess should I pick for my gun?

The NS-5818C has a 1/8" recess; choose it when your procedure calls for that stick-out length, otherwise select the flush or 1/4" recess versions offered in the same series.

What does the 1/8" recess do once the nozzle is on the torch?

It sets the contact-tip-to-work distance 1/8" behind the nozzle face, giving a slightly longer gas envelope for better shielding on open-root or out-of-position welds.

Which guns accept this Centerfire copper nozzle?

It fits Bernard BTB, Clean Air, Dura-Flux, FILTAIR, Q-Gun, S-Gun, XR-Aluma-Pro and XR-Pistol models that use the Small Centerfire series.
