0333-0310 - Victor 8-GPN Series 1 Propane/Natural Gas Cutting Tip, 12-Inch Capacity

Technical Overview of the Victor 8-GPN Cutting Tip

The Victor 0333-0310 8-GPN Cutting Tip is a high-capacity consumable designed for heavy industrial severing applications using alternative fuels. As a Series 1 tip, it is compatible with Victor's larger torch handles, such as the 300 series (e.g., 315FC) and compatible machine torches. The "GPN" designation indicates a General Purpose tip engineered specifically for Propane and Natural Gas. Unlike acetylene tips, this unit utilizes a two-piece construction consisting of a brass inner member with splined gas passages and a heavy-duty copper outer shell. This design creates a recessed tip end, which is essential for anchoring the flame of slower-burning fuel gases like propane, ensuring a stable preheat even in turbulent conditions.

This Size 8 tip represents the upper echelon of manual cutting capacity, rated to sever steel up to 12 inches (approximately 300mm) in thickness. To achieve this, the tip requires substantial gas volume and pressure. The manufacturer specifies a cutting oxygen pressure range of 60-70 PSIG and a fuel gas pressure of 10-14 PSIG. Consumption rates are significant, with total oxygen consumption estimated between 450-500 CFH and fuel gas consumption between 25-35 CFH. The preheat oxygen consumption alone ranges from 23-153 CFH depending on the flame adjustment. Operators must ensure their regulator and hose systems are capable of delivering these flow rates to prevent starvation during the cut.

The physical dimensions of the tip include a length of approximately 3.3 inches, standard for the Series 1 form factor. The copper alloy construction provides excellent thermal conductivity, helping to dissipate the intense heat generated during heavy section cutting, thereby prolonging the service life of the tip. This product is manufactured in Mexico and meets Victor's rigorous quality standards for flow consistency and flame geometry.
