CS1642 - Victor Cutskill 164-2 Acetylene Cutting Tip, 1 Inch Capacity

Technical Overview of the Victor Cutskill CS1642

The Victor Cutskill CS1642 is a high-performance replacement cutting tip engineered to meet the rigorous specifications of the Airco 164 series. Designated as a Size 2 tip, this consumable is precision-manufactured to facilitate the oxy-acetylene cutting process on mild steel plates with a thickness of up to 1 inch (approximately 25.4 mm). The tip features a one-piece copper alloy construction, which is standard for Airco-style acetylene consumables, ensuring optimal thermal conductivity and durability under high-temperature conditions.

Technically, the CS1642 is distinguished by its internal geometry, specifically a drill size of 55 for the cutting oxygen orifice. This calibration allows for a controlled oxygen stream capable of maintaining a cutting speed between 14 and 16 inches per minute (ipm) when operated at the recommended settings. The manufacturer specifies an oxygen pressure of 50 psig and a fuel gas (acetylene) pressure of 3 psig to achieve peak performance. These parameters ensure a clean kerf and minimal slag accumulation, provided the operator maintains the correct travel speed and torch angle.

A defining characteristic of the 164 series, and specifically this CS1642 model, is its "Heavy Preheat" classification. Unlike general-purpose tips (such as the 144 series), the 164 series is designed with a flat face and preheat orifices arranged to deliver a more concentrated and intense thermal output. This design is critical for special applications where the base material may have surface contaminants, rust, or mill scale that requires rapid heating to reach ignition temperature. The heavy preheat capability also assists in maintaining the cut on materials that dissipate heat quickly.

The seating mechanism is machined to strict tolerances to ensure a leak-proof seal with Airco-style cutting attachments and torches. Proper seating is vital for safety, preventing mixed-gas leakage within the torch head. Industrial MRO procurement specialists should note that while this is a Victor Cutskill product, it is fully interchangeable with OEM Airco 164-2 tips, offering a cost-effective solution without compromising on the metallurgical quality or dimensional accuracy required for industrial cutting operations.
