0333-0285 - Victor Size 3 Propylene Cutting Tip for Heavy Preheat

Victor 0333-0285 3-HPP Technical Specifications

The Victor 0333-0285 is a Size 3, Type HPP (High Performance Propylene) cutting tip assembly engineered for heavy industrial oxy-fuel cutting applications. This consumable is specifically designed for use with propylene fuel gas, distinguishing it from standard acetylene or propane tips by its internal geometry which optimizes the flow and mixture of propylene and oxygen. The HPP series is characterized by its heavy preheat capability, making it the preferred specification for beveling, scrap cutting, and operations involving heavy plate where rapid preheating is essential for process efficiency.

Operational parameters for the 3-HPP tip are defined for a material thickness range of 2 inches to 2-1/2 inches (50mm to 63mm). The tip supports a travel speed of approximately 9 to 12 inches per minute depending on the operator's proficiency and the condition of the base material. To achieve the rated performance, the manufacturer specifies a cutting oxygen pressure range of 45 to 50 PSIG and a preheat oxygen pressure range of 40 to 45 PSIG. Fuel gas pressure should be regulated between 5 and 9 PSIG. Proper pressure settings are critical for preventing backfires and ensuring a clean kerf.

The assembly features a two-piece design common for alternate fuel tips, consisting of a brass outer shell and a splined inner member. This construction facilitates the recessing of the flame end, protecting the tip face from damage during piercing or close-contact cutting. The heavy preheat pattern ensures that the steel reaches ignition temperature rapidly, even on plates with scale or rust. This specific model fits standard Victor heavy-duty cutting attachments and straight torches designed for alternate fuels.

Industrial MROs and welding engineers should note that this tip is not compatible with acetylene due to the different burning velocities and stoichiometric requirements. Using the 0333-0285 ensures compliance with Victor's safety and performance standards for propylene gas distribution systems. It is an essential stock item for facilities utilizing bulk or cylinder propylene for their thermal cutting processes, offering a balance of speed, gas efficiency, and cut quality for mid-to-heavy range plate thicknesses.
