Bernard NS-1200B Centerfire Nozzle

This Bernard NS-1200B Centerfire nozzle is a welding consumable designed for MIG guns in the Small Centerfire series. It fits Bernard and Miller equipment including BTB, Clean Air, Dura-Flux, FILTAIR, Q-Gun, S-Gun, XR-Aluma-Pro and XR-Pistol models. Welders replacing worn tips on compatible guns will find this component matches the original specification.

Centerfire series compatibility

The nozzle threads directly onto supported Bernard and Miller MIG guns without adapters or additional parts. Its Centerfire design aligns the contact tip and gas diffuser concentrically for consistent shielding coverage. No software, drivers or calibration are involved; the change is purely mechanical and restores the gun’s original gas flow geometry.

Proposition 65 notice

California Proposition 65 warnings apply because the product contains a chemical known to the state to cause cancer and birth defects or other reproductive harm. Buyers who require documentation free of such substances should verify alternative materials before purchase. The notice does not affect fit or function on the listed gun series.

Questions about this item

How often should the Bernard NS-1200B nozzle be replaced?

Replace the nozzle when the bore shows wear, spatter builds up inside, or gas flow becomes inconsistent. Inspect it each time you change the contact tip.

What limits continuous welding with the Bernard NS-1200B?

Heat soak in the copper body is the first limit; the nozzle must cool between long passes to avoid gas-flow distortion.

Does the Bernard NS-1200B nozzle get hot during all-day welding?

Yes, the copper body absorbs radiant heat and becomes too hot to touch within minutes of sustained use.
