0558005076 - Oxweld 1566HS Size 2 High Speed Propane Cutting Tip

Technical Overview of the ESAB 1566HS-2 Nozzle

The ESAB 1566HS-2 (SKU: 0558005076) is a high-performance cutting nozzle belonging to the renowned Oxweld 1566HS series. Engineered specifically for use with alternate fuel gases such as Propane and Natural Gas, this nozzle features a two-piece construction consisting of a brass inner member with splines and a chrome-plated copper outer shell. This design is critical for alternate fuels, as it creates a recess that anchors the flame, preventing it from blowing off the tip due to the lower burning velocity of propane compared to acetylene.

The "HS" designation stands for High Speed. These nozzles utilize a divergent bore geometry in the cutting oxygen passage. This expands the oxygen stream as it exits the tip, maintaining a coherent, supersonic jet that retains its energy over a greater distance. This results in cutting speeds that can be 20-30% faster than standard straight-bore tips, while also producing a narrower kerf and cleaner cut face. The Size 2 specification typically correlates to a cutting thickness range centered around 1 inch (25.4mm), depending on gas pressure settings and travel speed.

Durability is enhanced through a heavy chrome plating on the outer shell, which not only protects the copper from oxidation but also prevents molten slag and spatter from adhering to the nozzle during operation. This nozzle is designed to seat perfectly in Oxweld machine torches, including the C-32, C-66, C-77, and C-97 series, ensuring a leak-proof seal and optimal gas mixing.
