CS3GPN4 - Victor Cutskill Size 4 Propane Cutting Tip for 300 Series Torches

Victor Cutskill 3-GPN-4 Propane & Natural Gas Cutting Tip

The Victor Cutskill 3-GPN-4 is a robust and reliable cutting tip designed to maximize the efficiency of alternative fuel gases in industrial cutting applications. Engineered specifically for use with propane and natural gas, this tip belongs to the GPN (General Purpose Natural) family, which utilizes a specialized two-piece construction. Unlike single-piece acetylene tips, the 3-GPN-4 features a brass inner member with precision-machined splines and a heavy-duty copper outer shell. This design creates a recess at the tip face that anchors the flame, compensating for the lower burning velocity of propane and natural gas. This ensures a stable, high-intensity pre-heat flame that brings the steel to ignition temperature quickly and maintains it throughout the cut.

As a Series 3 consumable, this tip is sized to fit Victor's heavy-duty 300 Series torch handles and cutting attachments. It is not compatible with the smaller 100 Series equipment. The "Size 4" designation indicates its substantial cutting capability; it is rated to cut through steel plate up to 3 inches (approximately 75mm) thick. This makes it an excellent choice for structural steel fabrication, scrap yards, and heavy equipment repair where deep, clean cuts are required. The two-piece design also simplifies maintenance, as the outer shell can be removed to easily clean the inner splines of any soot or debris, extending the service life of the consumable.

Switching to propane or natural gas with the 3-GPN-4 tip can offer significant cost savings over acetylene without sacrificing cut quality. In fact, for thick plate cutting, propane often produces a cleaner face with less slag adhesion, reducing post-cut grinding time. Whether used in a hand torch or a machine cutting setup, the Victor Cutskill 3-GPN-4 delivers consistent performance and durability that professional welders and fabricators demand.
