CS15666 - Victor CutSkill Oxweld Style 1566 Propane Cutting Tip Size 6

Technical Overview of the Victor CutSkill CS15666

The Victor CutSkill CS15666 is a precision-engineered cutting tip designed to replicate the performance characteristics of the classic Oxweld 1566 series. This specific model represents a Size 6 configuration, intended for heavy-duty industrial cutting applications where material thickness ranges from approximately 6 inches (150mm) to 8 inches (200mm). Unlike single-piece acetylene tips, the CS15666 utilizes a two-piece construction consisting of a brass inner member and a copper outer shell. This design is critical for alternative fuels such as Propane and Natural Gas, which have different combustion velocities and stoichiometric requirements compared to Acetylene.

The internal geometry of the CS15666 features a heavy preheat spline pattern. Propane and natural gas burn at lower temperatures in the primary cone than acetylene, necessitating a more robust preheat flame to bring the base metal to its ignition temperature rapidly. The splines on the brass insert create a substantial volume of preheat flame surrounding the central cutting oxygen stream, ensuring that the cut remains stable even when traversing scaled or rusty surfaces on thick plates. The separation of the inner and outer parts also allows for easier maintenance; if the splines become clogged with carbon or slag, the outer shell can be removed to access and clean the gas passages effectively.

Compatibility is a key specification for this component. The CS15666 is manufactured to fit Oxweld-style torch heads, including common models like the C-32, C-66, and compatible machine torches. It is not compatible with standard Victor-style torches (which use the 1-101 or GPN series). Industrial MROs and procurement specialists should verify the torch head style before specification. The tip is rated for use with standard oxygen and fuel gas pressures appropriate for Size 6 orifices, typically requiring significantly higher oxygen flow rates to maintain the cutting stream through 8 inches of steel.
