0558009318 - ESAB 1.8mm Water Injection Plasma Nozzle (5-Pack)

Precision Engineering for High-Performance Plasma Cutting

The ESAB 0558009318 Water Injection Nozzle is a critical component for industrial plasma cutting systems that demand precision and longevity. Engineered with a specific 1.8mm (.070") orifice, this nozzle is designed to constrict the plasma arc effectively, delivering high energy density to the workpiece. This specific bore diameter is calibrated for optimal performance within its amperage range, ensuring clean, dross-free cuts on conductive metals.

What sets this nozzle apart is its integration into ESAB's water injection technology. Unlike standard air-cooled or gas-shielded nozzles, water injection systems utilize a swirling vortex of water to constrict the arc further and provide direct cooling to the nozzle bore. This thermodynamic advantage significantly reduces the erosion rate of the copper orifice, maintaining cut quality over a much longer lifespan compared to conventional dry plasma systems. The rapid cooling effect also minimizes the heat-affected zone (HAZ) on the material, preserving the metallurgical integrity of the cut edge.

This product is supplied as a pack of five, reflecting the needs of high-volume industrial environments where uptime is paramount. Each nozzle is manufactured to tight tolerances, ensuring that flow dynamics and electrical characteristics remain consistent from one replacement to the next. For facility managers and welding engineers, choosing genuine ESAB consumables like the 0558009318 ensures that your capital equipment operates at its rated efficiency, protecting the torch head from premature wear caused by inferior aftermarket deviations.
