CS1645 - Victor CutSkill Airco Style 164-5 Acetylene Tip, 4-Inch Cut

Technical Overview of the Victor CS1645 Airco Style 164-5

The Victor CS1645 is a precision-engineered cutting tip designed to replicate the performance specifications of the Airco 164 series, specifically the size 5 configuration. This consumable is manufactured to strict tolerances, ensuring seamless compatibility with Airco-style oxy-acetylene torches. The tip features a specific internal geometry optimized for acetylene gas, utilizing a drill size of 47 for the cutting oxygen orifice. This bore diameter allows for a substantial oxygen stream capable of oxidizing ferrous metal up to 4 inches (approx. 100mm) in thickness.

Operational parameters for the CS1645 are distinct and must be adhered to for optimal safety and cut quality. The manufacturer recommends a cutting oxygen pressure of 60 psig. The preheat fuel gas (acetylene) should be regulated to approximately 4 psig. At these settings, the tip supports a travel speed ranging from 7 to 10 inches per minute (ipm). The 164 series is characterized by its heavy preheat capability, making it particularly suitable for applications where rapid heat transfer is required to bring thick base metals to ignition temperature quickly, or when cutting materials with scale or rust.

Constructed from high-grade copper alloy, the tip is designed to resist deformation under high thermal loads. The seating surfaces are machined to ensure a leak-proof seal within the torch head, preventing dangerous gas mixing or backfires. This unit serves as a direct replacement for OEM Airco 164-5 tips, providing industrial-grade performance for maintenance, repair, and fabrication environments requiring deep section cutting.
