0558005089 - Oxweld 1566HS Size 4 Machine Cutting Tip for MAPP/FG-2

ESAB Oxweld 1566HS-4 High-Speed Machine Cutting Nozzle

The ESAB 0558005089 is a premium-grade 1566HS-4 series cutting nozzle engineered specifically for industrial machine cutting applications utilizing MAPP and FG-2 fuel gases. As part of the renowned Oxweld product line, the 1566HS series represents the pinnacle of high-speed cutting technology, designed to maximize throughput in automated environments. This specific nozzle, Size 4, is calibrated to handle substantial plate thicknesses, providing a balance of preheat intensity and cutting oxygen velocity required for clean, precise severance of carbon steel.

Technically, the 1566HS (High Speed) designation refers to the internal geometry of the cutting oxygen bore. Unlike standard cylindrical bores, the 1566HS features a divergent bore design. This aerodynamic shaping accelerates the cutting oxygen stream to supersonic velocities as it exits the nozzle, maintaining a tight, columnar stream over greater distances. This results in narrower kerf widths, sharper top edges, and the ability to increase machine travel speeds significantly compared to standard tips. The preheat ports are meticulously arranged to ensure stable combustion of MAPP and FG-2 gases, which have different flame propagation rates and BTU outputs compared to acetylene.

Construction-wise, the nozzle employs a robust two-piece design typical for alternative fuel tips. The inner member features precision-milled splines for gas mixing, while the outer shell is heavily chrome-plated. This plating serves a dual purpose: it reflects intense radiant heat from the workpiece, keeping the tip cooler during prolonged cutting cycles, and it prevents molten spatter from adhering to the nozzle face, thereby reducing maintenance downtime. The ESAB 1566HS-4 is an essential consumable for fabrication shops seeking to optimize their oxy-fuel machine cutting processes with alternative fuels.
