Victor 5-3-GPN Propane/Natural Gas Cutting Tip, Size 5

Heavy-Duty Cutting Power with Propane Efficiency

For welders and fabricators looking to cut thick steel without the high cost of acetylene, the Victor 5-3-GPN Cutting Tip (0333-0404) is the ideal solution. This Size 5 tip is a powerhouse, capable of slicing through steel plate ranging from 4 to 5 inches thick. Whether you are working in a scrap yard, on a demolition site, or in a heavy fabrication shop, this tip delivers the heat and oxygen flow needed to make clean, severance-quality cuts on massive workpieces using Propane or Natural Gas.

Victor's GPN series is renowned for its reliability and durability. The 5-3-GPN features a two-piece design that is specifically engineered for alternative fuels. Propane and natural gas burn at different rates and require different mixing ratios compared to acetylene. The two-piece construction of this tip allows for a heavy preheat flame that stays lit even when the cutting oxygen lever is fully engaged. The outer copper shell protects the inner brass components, and the slightly recessed face helps prevent the tip from getting clogged or damaged if you accidentally touch the molten pool, a common occurrence when cutting thick, dirty metal.

Using the 5-3-GPN is straightforward for anyone familiar with Victor equipment. It fits standard Victor Series 3 torches (often referred to as the 300 series large-body torches). Simply swap out your acetylene tip for this GPN tip, adjust your regulator settings to the recommended 45-55 PSIG for oxygen and 8-12 PSIG for fuel, and you are ready to cut. The transition to propane or natural gas not only saves money on consumables but also eliminates the withdrawal rate limitations associated with acetylene cylinders, making this tip a safer and more economical choice for heavy heating and cutting tasks.

Invest in genuine Victor quality to ensure your cuts are smooth and your equipment lasts. The 0333-0404 tip provides a consistent 0.14-inch kerf and cutting speeds up to 10 inches per minute, helping you get the job done faster and with less cleanup grinding required afterwards.
