0333-0322 - Victor Size 0 HPN Propane Cutting Tip

Technical Overview of the Victor 0333-0322 0-HPN Cutting Tip

The Victor 0333-0322 0-HPN Cutting Tip is a high-performance consumable engineered specifically for industrial cutting applications utilizing Propane or Natural Gas. As part of the HPN series, this tip is distinguished by its "Heavy Preheat" capability. Unlike standard general-purpose tips, the HPN design features a spline configuration that delivers a more robust preheat flame. This technical attribute is critical when working with alternative fuel gases, which have a lower flame temperature compared to acetylene, or when cutting materials that are heavily oxidized, painted, or coated.

Structurally, the 0-HPN utilizes a two-piece design, consisting of an outer brass shell and an inner copper insert. This separation of materials is essential for propane and natural gas applications; the copper insert withstands the intense heat of the cutting oxygen stream, while the brass shell protects the assembly and forms the preheat flame pattern. The two-piece construction also facilitates easier maintenance, as the components can be separated for thorough cleaning of the splines if they become clogged with slag or carbon deposits.

This specific model is a Size 0 tip, calibrated for cutting mild steel with a thickness of approximately 3/8 inch (10mm). It is designed to fit Victor heavy-duty cutting attachments and straight torches, commonly referred to as the 300 Series (or compatible "Victor Style" heavy-duty equipment). The tip seats are precision-machined to ensure a leak-proof metal-to-metal seal, maintaining safety and efficiency during operation. Users in structural fabrication, scrap yards, and heavy equipment repair rely on the 0333-0322 for its consistency and ability to maintain a stable flame even in adverse conditions.

By optimizing the oxygen and fuel gas mixture for heavy preheat, the 0-HPN minimizes the time required to bring the base metal to kindling temperature, thereby increasing overall throughput and productivity in industrial environments.
