CS2631 - Victor Cutskill Airco Style 263-1 Acetylene Tip

Technical Specifications: Victor Cutskill CS2631 (Airco 263-1)

The Victor Cutskill CS2631 is a direct replacement cutting tip for the Airco 263 series, specifically sized as a #1. This tip is designed for oxy-acetylene cutting processes and is distinguished by its heavy preheat configuration. Unlike standard general-purpose tips (such as the 144 series), the 263 series utilizes a spline or port configuration that delivers a more robust preheat flame. This technical feature is critical for welders and fabricators working on structural steel or scrap where surface contaminants like rust, primer, or scale can disrupt the cutting oxygen stream.

Operational Parameters:

The Size 1 orifice is optimized for cutting mild steel with a thickness of 3/4" (19mm) to 1" (25mm). For optimal performance, operators should set their oxygen pressure between 30-35 PSI and acetylene pressure between 3-5 PSI, adjusting slightly based on torch length and hose restrictions. The tip utilizes a flat seat design, which must be seated correctly in the torch head and tightened with the appropriate nut to prevent backfires or leaks. The copper alloy construction ensures excellent heat dissipation, reducing the risk of tip overheating during prolonged cuts.

Why Choose the 263 Style?

While general-purpose tips are sufficient for clean plate, the 263 style is the welder's choice for "dirty" work. The aggressive preheat allows for faster starts at the edge of the plate and maintains the puddle fluidity even when encountering heavy oxidation. This reduces the need for grinding or cleaning the material prior to cutting, saving valuable prep time. The Victor Cutskill manufacturing process ensures that the oxygen bore is smooth and concentric, providing a clean kerf with minimal slag accumulation.
