0333-0309 - Victor 7-GPN Propane/Natural Gas Cutting Tip, Size 7

Technical Overview of the Victor 7-GPN Cutting Tip

The Victor 0333-0309 7-GPN Cutting Tip is a specialized consumable designed for industrial oxy-fuel cutting processes utilizing Propane or Natural Gas. As part of the GPN series, this tip features a robust two-piece construction, distinguishing it from standard single-piece acetylene tips. The design incorporates a brass inner splined member and a copper outer shell. This configuration is engineered to optimize the preheat flame characteristics required for alternative fuels, which have different combustion velocities and heat distributions compared to acetylene.

With a Tip Size of 7, this component is intended for heavy-duty applications involving substantial material thickness. The separation of the inner and outer parts allows for easier cleaning and maintenance, extending the service life of the consumable in harsh industrial environments. The splined inner piece ensures a stable and concentric preheat flame, while the precision-drilled cutting oxygen orifice delivers a high-velocity stream for efficient slag removal and clean kerf lines.

This tip is compatible with standard Victor heavy-duty cutting attachments and hand torches that accept GPN style consumables. It is designated as Type 1, indicating its specific seat and operational configuration within the Victor product ecosystem. Professionals relying on propane or natural gas for cost-efficiency and availability will find the 7-GPN to be an essential component for maintaining productivity in scrap yards, fabrication shops, and structural steel projects.

Proper gas pressure settings are critical for optimal performance. Users should consult Victor's cut charts for Size 7 GPN tips to determine the correct oxygen and fuel gas pressures based on the specific thickness of the steel being processed. The 0333-0309 ensures reliability and consistency, hallmarks of the Victor brand's legacy in gas equipment.
