15Z17 - Oxweld 1502 Series Acetylene Cutting Tip Size 4 (1/2 Inch Capacity)

Technical Overview of the ESAB Oxweld 1502 Series Size 4 Cutting Tip

The ESAB Oxweld 1502 Series Size 4 Cutting Tip (SKU: 15Z17) is a precision-engineered consumable designed for oxy-acetylene cutting processes. This one-piece nozzle is specifically calibrated to cut mild steel with a thickness of 1/2 inch (12.7 mm). It features a medium preheat configuration utilizing six distinct preheat holes, which provides a balanced thermal distribution suitable for general-purpose applications, including the cutting of dirty or scaled plate and beveling operations.

Technically, the nozzle operates within a specific gas pressure envelope to maintain flame stability and cut quality. The recommended cutting oxygen pressure ranges from 35 to 40 PSIG, while the preheat oxygen requires 20 to 25 PSIG. The acetylene fuel gas should be regulated between 5 and 7 PSIG. Under these parameters, the tip achieves a gas consumption rate of 65-75 CFH for total oxygen and 8-10 CFH for acetylene. The fluid dynamics of the internal geometry allow for a cutting speed of 15 to 23 inches per minute, producing a narrow average kerf width of 0.065 inches, which minimizes material waste and post-cut machining.

The 1502 Series is manufactured to tight tolerances, ensuring concentricity of the gas streams. This results in a stable, high-velocity oxygen stream that effectively oxidizes the metal and clears the slag. The physical dimensions of the tip are approximately 3.55 inches in length with a 0.9-inch diameter, designed to fit securely into all standard Oxweld cutting torches. The copper alloy construction provides excellent thermal conductivity, preventing tip overheating during prolonged machine or hand cutting cycles.

Engineers and fabrication managers should note that this tip is strictly for use with Acetylene gas. The medium preheat characteristic makes it a versatile choice for maintenance and repair operations (MRO) where surface preparation of the base metal may not always be perfect. The tip's design supports both straight cuts and beveling, offering flexibility across various industrial fabrication scenarios.
