CS1383 - Victor CutSkill 138-3 Acetylene Cutting Tip, Size 3

Technical Overview of the Victor CutSkill CS1383

The Victor CutSkill CS1383 is a specialized oxy-acetylene cutting tip designed to replicate the performance and fitment of the classic Airco 138 series. Engineered for professionals requiring precise replacement parts, this tip features a Size 3 orifice configuration, calibrated to handle material thicknesses between 1-1/2 inches (38mm) and 2 inches (50mm). The tip utilizes a one-piece construction method, which is the industry standard for acetylene gas service, ensuring optimal thermal conductivity and flame characteristics.

Compatibility is a key feature of the CS1383. It is machined with the specific seating geometry required for Airco-style cutting attachments and hand torches. This ensures a metal-to-metal seal that maintains gas separation until the mixing point (in the torch head or tip, depending on system design), although 138 series tips are typically used with equal pressure or injector style torches designed for this specific seat type. The copper alloy body is resistant to heat deformation and spatter adhesion, prolonging the service life of the consumable under standard industrial operating conditions.

Flow dynamics for the Size 3 tip are optimized for general fabrication duties. The preheat ports are arranged to provide sufficient thermal energy to rapidly bring 2-inch plate to kindling temperature without overheating the kerf edge. The central cutting oxygen bore is drilled and swaged to produce a coherent jet, minimizing turbulence and ensuring a straight, clean cut face. This product is part of the Victor CutSkill line, which balances professional-grade performance with value, making it a suitable stock item for MRO cribs and fabrication supply inventories.
