3-GPN-2 - Flame Tech 3-GPN-2 Propane Cutting Tip, Size 2, Victor Style

Technical Specifications and Compatibility

The Flame Tech 3-GPN-2 is a high-performance cutting tip designed for industrial oxy-fuel cutting applications utilizing alternative fuels. Specifically engineered for Propane and Natural Gas, this tip belongs to the GPN series, which is characterized by a two-piece construction. The design features a heavy-duty copper outer shell and a precision-machined brass inner insert. This separation of materials allows for optimized heat distribution and durability under the distinct combustion characteristics of propane gas.

This specific model is a Size 2 tip, which typically supports a cutting capacity range of approximately 1 inch to 1-1/2 inches (25mm to 38mm), depending on gas pressure and travel speed. It is manufactured to be fully compatible with Victor 100 Series torch handles and cutting attachments, making it a direct replacement for the Victor 3-GPN-2. The 3-Series style is generally associated with medium-duty equipment, distinguishing it from the larger 1-Series tips used in heavy-duty 300 Series torches.

Maintenance of the 3-GPN-2 is straightforward due to its separable design. Unlike single-piece acetylene tips where carbon buildup must be carefully reamed out, the outer shell of this propane tip can be slid off to expose the splines of the inner member. This allows operators to easily wipe away soot or slag that may accumulate during operation, ensuring consistent gas flow and flame stability. Proper seating of the tip within the torch head is critical to prevent backfires and ensure leak-free operation.
