639605 - Oxweld 1566HS Size 2.5 Machine Cutting Tip for Propane/Natural Gas

Precision Machine Cutting with the Oxweld 1566HS Series

The ESAB Oxweld Internal 1566 Series Size 2 1/2 Two-Piece Alternate Fuels Nozzle is a high-performance consumable designed for industrial machine cutting applications. Engineered to meet the rigorous demands of automated cutting tables, this nozzle (SKU 639605) is part of the renowned 1566HS (High Speed) family. It is specifically calibrated for use with alternate fuel gases, such as propane and natural gas, offering a cost-effective solution for facilities processing heavy carbon steel plate. The nozzle features a robust two-piece design, consisting of a durable outer shell and a precision-machined internal spline, which optimizes the gas mixture for maximum thermal efficiency and flame stability.

With a cutting capacity of 2 1/2 inches, this nozzle is built to handle substantial material thicknesses while maintaining impressive travel speeds. Operators can achieve cutting speeds ranging from 10 to 17 inches per minute, significantly enhancing production throughput compared to standard tips. The "High Preheat" designation indicates that this nozzle delivers a substantial volume of preheat flame, which is essential for rapid piercing and maintaining the puddle temperature when using cooler-burning alternate fuels. This ensures that the cutting oxygen stream can effectively oxidize the metal throughout the entire cut duration without losing prime.

Technical specifications for the 1566HS Size 2 1/2 are optimized for industrial gas supply systems. The nozzle requires a cutting oxygen pressure of 90 PSIG and a preheat oxygen pressure between 25 and 55 PSIG. Fuel gas pressure is efficiently managed at a low range of 3 to 5 PSIG. Gas consumption is engineered for balance, with a total oxygen draw of 275-295 CFH and fuel consumption of 8-15 CFH. These parameters ensure that the nozzle delivers a high-velocity oxygen stream capable of producing smooth, square cuts with minimal slag adhesion, reducing the need for extensive post-cut machining or grinding.

Manufactured in Mexico to ESAB's exacting standards, the Oxweld 1566 series represents the pinnacle of oxy-fuel machine cutting technology. The physical dimensions of the tip (3.55" x 0.9" x 0.9") ensure compatibility with standard Oxweld machine torches. By utilizing a divergent bore design typical of high-speed tips, the 1566HS expands the cutting oxygen stream as it exits the nozzle, maintaining a coherent jet that retains energy over a greater distance. This results in straighter cuts and the ability to handle plate irregularities with ease.
