GPN-5 - Victor Style GPN-5 Propane Cutting Tip, Size 5, 2-Piece

Technical Overview of the GPN-5 Cutting Tip

The GPN-5 Cutting Tip is a high-performance consumable designed for industrial oxy-fuel cutting applications utilizing alternative fuels such as Propane and Natural Gas. Engineered as a direct replacement for Victor-style equipment, this tip is fully compatible with Victor 300 Series cutting attachments and straight torches. It belongs to the 1 Series family of tips, characterized by its robust performance and standard pressure requirements.

This specific model, the Size 5, is engineered for heavy material processing, boasting a substantial cutting capacity of 4 to 5 inches. It operates efficiently with a cutting oxygen pressure range of 50-55 PSIG and a flow rate of 330-360 SCFH, ensuring deep penetration and effective slag removal. The preheat oxygen flow is calibrated between 23-108 SCFH, while the fuel gas requirement is a modest 8-12 PSIG with a flow of 20-30 SCFH. These specifications allow for a controlled cutting speed of approximately 6 to 9 inches per minute, depending on the base material condition and operator technique.

Structurally, the GPN-5 utilizes a 2-piece design, consisting of a brass inner member with splines for the preheat gas and a copper outer shell. This construction is superior for propane and natural gas applications as it allows the preheat flame to anchor properly at the tip face, preventing starvation or blow-offs common with slower-burning gases. The V-Style geometry ensures a tight seal within the torch head, minimizing the risk of backfires and leaks.
