GPN-0 - Flame Tech GPN Series Propane Cutting Tip, Size 0, Victor Style

Technical Overview of the Flame Tech GPN-0 Cutting Tip

The Flame Tech GPN-0 is a high-performance replacement cutting tip designed to meet the rigorous demands of industrial metal cutting. Engineered as a direct alternative to the Victor GPN series, this tip is fully compatible with Victor 300 Series cutting attachments and straight torches. The "GPN" designation indicates its specific optimization for General Purpose Natural gas and Propane applications. Unlike acetylene tips, which are typically one-piece, the GPN-0 utilizes a two-piece construction consisting of a heavy-duty outer copper shell and a brass internal spline. This design is critical for alternate fuels, as it allows for the recessing of the inner member, creating a stable anchoring point for the flame even at the lower burning velocities characteristic of propane and natural gas.

The Size 0 specification of this tip is calibrated for cutting mild steel with a thickness range of approximately 3/8 inch to 1/2 inch (10mm to 12mm). The separation of the outer shell and inner insert simplifies maintenance; operators can easily disassemble the tip to clean out slag or carbon buildup from the preheat splines, significantly extending the consumable's operational life. The external copper shell is manufactured to withstand high radiant heat and resist the adhesion of spatter, ensuring consistent performance in continuous cutting environments.

Fluid dynamics within the tip are optimized to maintain a coherent oxygen cutting stream while providing a heavy preheat flame necessary for the slower heat transfer of propane. This makes the GPN-0 an excellent choice for applications where edge quality and fuel economy are prioritized over preheat speed. Users should ensure their torch equipment is equipped with the appropriate "T" grade hose and regulators compatible with alternate fuels when utilizing this tip.
