OVERVIEW

Genuine Bernard 4395A Insulated Brass Nozzle

The Bernard 4395A is a premium-quality replacement nozzle designed for heavy-duty industrial welding applications. Engineered specifically for Bernard Q-Gun, S-Gun, and T-Gun MIG welding guns, this nozzle is rated for 300-amp service, making it an ideal choice for medium to heavy fabrication tasks. The nozzle features a robust brass construction which offers excellent thermal conductivity, helping to dissipate heat rapidly during prolonged welding arcs. This thermal efficiency extends the lifespan of the consumable and reduces the adhesion of weld spatter.

This specific model features a tapered geometry with a 1/2-inch (12.7mm) bore orifice. The tapered design is critical for welders who require enhanced visibility of the weld puddle or need to access tight corners and filleted joints where larger, cylindrical nozzles cannot reach. Being fully insulated, the 4395A protects the gas diffuser and contact tip from electrical shorts if the nozzle accidentally contacts the workpiece, ensuring safer operation and protecting your equipment investment.

As an OEM part, the Bernard 4395A guarantees perfect fitment and gas seal integrity with compatible Bernard head assemblies. It works seamlessly with standard elliptical contact tip systems and corresponding gas diffusers. Whether you are welding mild steel, stainless, or aluminum, maintaining a consistent shielding gas envelope is paramount, and this nozzle delivers a focused gas stream to minimize porosity and oxidation.

FAQ

The Bernard 4395A nozzle has a 1/2-inch (12.7mm) bore orifice.

Yes, the 4395A is a fully insulated brass nozzle, which helps prevent electrical shorts if it contacts the workpiece.

This nozzle is rated for welding applications up to 300 Amps.

It is compatible with Bernard Q-Gun, S-Gun, and T-Gun series MIG guns that utilize the standard nozzle and diffuser system.

A tapered nozzle provides better visibility of the weld puddle and allows for better access into tight corners or V-grooves compared to cylindrical nozzles.

It is made of high-quality brass, which offers excellent durability and heat dissipation properties.

No, the 4395A is typically for the standard elliptical tip system. Centerfire systems usually use 'N' series nozzles (e.g., N-1218C), although adapters may exist.
