0333-0286 - Victor 4-HPP Propane & Natural Gas Cutting Tip Size 4

Technical Overview of the Victor 4-HPP Cutting Tip

The Victor 0333-0286 4-HPP Cutting Tip is a specialized consumable engineered for high-efficiency oxygen-fuel cutting using alternative fuels such as Propane and Natural Gas. Unlike standard acetylene tips, the HPP (High Performance Propane) series is designed with specific internal geometries that optimize the flow and mixture of oxygen and fuel gas. This is critical because propane and natural gas have different combustion velocities and BTU outputs compared to acetylene. The HPP design ensures a stable, high-temperature preheat flame that is essential for piercing and maintaining the cut on heavy carbon steel plates.

This specific model is a Size 4 tip, which places it in the heavy-duty category of cutting consumables. A Size 4 orifice typically supports cutting capacities in the range of 3 to 5 inches (approximately 75mm to 125mm), depending on the specific gas pressures and torch travel speed employed. The tip is manufactured to Victor's rigorous standards, ensuring concentricity of the cutting oxygen stream. A concentric stream is vital for achieving a kerf that is straight and narrow, minimizing material waste and reducing the need for secondary machining or grinding operations.

The 0333-0286 assembly is compatible with Victor-style heavy-duty hand torches and machine torches that accept standard Victor cutting tips. It is particularly well-suited for industrial environments where propane is the preferred fuel gas due to its cost-effectiveness and availability. The tip's construction features durable copper and brass alloys capable of withstanding the high reflected heat generated during the cutting of thick sections. Proper maintenance, including regular cleaning of the preheat and cutting orifices, will extend the service life of this component and maintain optimal process parameters.

Operators should verify their regulator settings against Victor's cut charts for Size 4 Propane tips to ensure safety and performance. Typically, alternative fuels require different oxygen-to-fuel ratios than acetylene, and the HPP tip is calibrated to deliver the precise mixture required for a neutral or slightly oxidizing preheat flame as dictated by the application.
