Xtrweld NS-5800B Welding Nozzle 5/8 in Flush Brass 2 Pack

Product Description

The XTRWELD NS-5800B is a flush-style MIG welding nozzle machined from brass, designed as a direct-fit component for Bernard Centerfire Series MIG guns. The 5/8-inch bore size provides consistent shielding gas coverage across the weld puddle, and the flush profile keeps the nozzle face clear for tight-access welds. This nozzle is a consumable part replaced routinely by welders and MIG technicians during scheduled maintenance or after spatter buildup degrades gas flow. Each pack contains two nozzles, reducing downtime when a swap is needed at the gun.

This nozzle is suited for MIG welding applications in fabrication shops, light manufacturing, and field repair environments where Bernard Centerfire Series guns are in use. The flush nozzle geometry is commonly selected for flat and horizontal welds where a low-profile tip face is preferred. The brass construction handles moderate heat and resists spatter adhesion better than uncoated steel alternatives, making it appropriate for short-circuit and spray transfer processes on mild steel, stainless, and similar base metals.

Key Features

• 5/8-inch bore diameter for consistent shielding gas coverage at the weld zone
• Flush nozzle profile suited for flat, horizontal, and tight-access weld positions
• Brass construction offers solid thermal resistance and reduced spatter adhesion
• Direct replacement for Bernard Centerfire Series MIG gun nozzles
• Two nozzles per pack for back-to-back replacement without reordering delay

Compatibility

Designed as a direct-fit replacement nozzle for Bernard Centerfire Series MIG welding guns. Verify gun model and nozzle thread type before installation.

Installation Notes

Installation is performed by MIG welders or welding equipment technicians. Before replacing the nozzle, disconnect the MIG gun from the wire feeder and allow the contact tip and nozzle to cool completely. Remove the existing nozzle by unscrewing or pulling it free depending on the retention style, clear any spatter from the diffuser, and thread or press the NS-5800B into position until seated. Inspect the contact tip for wear and replace if needed before returning the gun to service.
