CS1643 - Victor Cutskill Airco Style 164-3 Acetylene Tip, Size 3

Technical Overview of the Victor Cutskill CS1643

The Victor Cutskill CS1643 is a precision-engineered replacement cutting tip designed to meet the rigorous standards of the Airco Style 164 series. This component is manufactured to facilitate high-quality oxy-acetylene cutting operations, specifically tailored for industrial environments where reliability and accuracy are paramount. The tip is classified as a Size 3 consumable, engineered to handle material thicknesses up to 1-3/4 inches. It features a robust construction that withstands high thermal stress, ensuring longevity even under continuous operational cycles.

Technically, the CS1643 is characterized by its specific orifice configuration. It utilizes a drill size of 53, which is critical for maintaining the optimal flow rate and velocity of the preheat flames. The internal geometry is designed to stabilize the gas mixture, preventing flashbacks and ensuring a neutral flame profile. For optimal performance, this tip requires a cutting oxygen pressure of 50 PSIG and a fuel gas (acetylene) pressure of 3 PSIG. These parameters allow the operator to achieve a cutting speed range of 11 to 15 inches per minute (IPM), balancing thermal input with travel speed to minimize the heat-affected zone (HAZ).

The G-Series Airco Style 164 design incorporates a heavy preheat pattern. This technical feature is essential for applications involving materials with surface contaminants, rust, or mill scale, where rapid ignition and sustained temperature are required to maintain the cutting reaction. The tip seats securely into standard Airco style torches, utilizing a metal-to-metal seal that prevents gas leakage and ensures efficient transmission of the gas stream from the torch head to the workpiece. By adhering to strict dimensional tolerances, Victor Cutskill ensures that the CS1643 provides a direct, hassle-free fit for compatible equipment.

In terms of fluid dynamics, the tip is optimized for the combustion characteristics of acetylene. The ratio of oxygen to fuel is calibrated to produce a high-intensity flame cone, maximizing the calorific value of the fuel gas. This results in a clean, narrow kerf and efficient slag ejection. Industrial MRO professionals can rely on the CS1643 for consistent performance in fabrication shops, scrap yards, and maintenance facilities where Airco style equipment is the standard.
