American Torch Tip GPN-0 Cutting Tip

The American Torch Tip GPN-0 is a Victor Series cutting tip designed for handheld or machine torches using natural gas or propane. It serves general-purpose cutting tasks on steel between three-eighths and one-half inch thick. Operators who need a medium-preheat flame for consistent starts will find it suitable. Buyers needing to cut material outside that thickness range or using acetylene fuel should select a different tip.

GPN Series Fuel and Oxygen Parameters

The tip operates with a fuel flow of 8 to 10 scfh at 3 to 5 psig and requires 23 to 108 scfh oxygen for preheat plus 40 to 55 scfh for cutting. Maximum cutting speed reaches 24 inches per minute while the minimum is 18 inches per minute, producing a kerf of 0.06 inch. These fixed flow and pressure windows limit the tip to the stated thickness range; exceeding them will degrade cut quality. Shops without flow meters capable of these exact settings cannot use the tip reliably.

Installing the GPN-0 on Victor Torches

The tip threads directly onto compatible Victor handheld or machine torches without tools, so installation takes only seconds. The most common issue is mismatching the GPN series to a torch head cut for a different series, which causes leaks or poor flame shape. Verify the torch model accepts GPN tips before fitting. Debris in the seat or damaged O-rings will also disrupt gas flow, so inspect both surfaces each time the tip is changed.
