54C313 - Walter N-5818-C Centerfire Style MIG Nozzle, 5/8 in Bore, 1/8 in Recess

Reliable Gas Coverage for Quality Welds

Keep your MIG gun running smoothly with this robust 5/8-inch bore nozzle. Welding professionals know that consistent gas coverage is the key to a clean, porosity-free weld, and this nozzle delivers exactly that. The 5/8-inch opening is the industry standard for general-purpose and heavy fabrication, providing a stable shield of gas around the weld pool even in drafty conditions or when moving quickly. Its copper construction stands up to the intense heat of the arc, resisting deformation and ensuring a long service life.

One of the standout features of this nozzle is the 1/8-inch tip recess. By keeping the contact tip tucked away, you reduce the risk of the tip shorting out against the workpiece and protect it from the direct heat of the puddle. This recess also creates a small buffer zone that helps prevent spatter bridges, keeping your gas flow uninterrupted. If you are tired of wrestling with threaded nozzles that get stuck, you will appreciate the threadless, drop-in style of this unit. It slides over the diffuser and locks in place with the retaining spring, making changeouts a breeze—even with gloved hands.

Perfect for use with standard solid wires or flux-cored wires requiring gas shielding, this nozzle is a versatile addition to your welding toolkit. It is compatible with Bernard Centerfire style systems, making it an easy replacement for your existing consumables. Pair it with a good nozzle gel or anti-spatter spray, and you will spend less time cleaning and more time welding.
