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

High-Performance MIG Consumable

The Walter N-5818-C is a premium quality MIG welding nozzle designed to deliver consistent shielding gas coverage and reliable performance in industrial welding environments. Modeled after the popular Centerfire series, this nozzle features a threadless, drop-in design that simplifies maintenance and reduces downtime. The nozzle is constructed from high-grade copper, which offers excellent thermal conductivity, helping to dissipate heat away from the front end of the gun and prolonging the life of both the nozzle and the contact tip.

With a 5/8-inch bore diameter, this nozzle provides a broad gas envelope, making it suitable for medium to heavy-duty welding applications where porosity control is critical. The 1/8-inch contact tip recess is a key feature, positioning the tip slightly back inside the nozzle. This recess helps protect the contact tip from radiant heat, reduces the likelihood of burn-back, and minimizes the accumulation of spatter on the tip face. This geometry is particularly beneficial when welding at higher amperages or when using spray transfer modes.

Designed for compatibility with Centerfire style gas diffusers, the N-5818-C ensures a secure fit without the need for threads that can seize or cross-thread. The smooth exterior and interior surfaces facilitate easy cleaning of spatter, especially when used in conjunction with anti-spatter compounds or nozzle dips. Whether for fabrication, automotive repair, or general manufacturing, this nozzle provides the durability and performance required for high-quality welds.
