N-A5818C - Bernard AccuLock S Copper MIG Nozzle, 5/8" Bore, 1/8" Recess

Maximize Performance with the Bernard AccuLock S Nozzle

Tired of nozzles that rattle loose or overheat in the middle of a long weld? The Bernard N-A5818C AccuLock S MIG Nozzle is designed to solve the most common frustrations welders face on the shop floor. Whether you are running a Bernard BTB gun or a Miller MDX-250, this nozzle upgrades your front-end consumables to a heavy-duty industrial standard. The all-copper construction ensures rapid heat dissipation, keeping your front end cooler even during extended arc-on times.

The "Load and Lock" Advantage

The standout feature of the AccuLock S series is the Load and Lock technology. Unlike traditional nozzles that rely solely on friction or fine threads that easily strip, the AccuLock S system uses a robust steel retaining ring on the diffuser. When you thread this nozzle on, it stays locked in place, regardless of how much you move or manipulate the gun. This secure fit not only prevents the nozzle from falling off but also ensures concentricity, keeping your wire dead-center in the gas flow for consistent weld quality.

Optimized for Visibility and Protection

The N-A5818C features a 5/8-inch bore and a 1/8-inch tip recess. This recess is the "sweet spot" for many welders—it protects your contact tip from the intense heat of the puddle and reduces the chance of spatter bridging, while still allowing excellent visibility of the weld pool. The 5/8-inch opening provides ample gas coverage, making it ideal for spray transfer or higher amperage short-circuit MIG welding. By keeping the contact tip recessed, you also reduce the frequency of tip burn-backs, saving you money on consumables in the long run.
