Victor 4-3-GPN Propane/Natural Gas Cutting Tip, Size 4

Reliable Cuts for Heavy Fabrication

When you are out in the field or deep in the shop, you need a cutting tip that can handle the heat and deliver a clean cut every time. The Victor 4-3-GPN (0333-0403) is the go-to choice for welders and fabricators running Propane or Natural Gas setups. Designed to fit your trusty Victor 300 series torch handle, this Size 4 tip is a beast, capable of slicing through 3 inches of steel without breaking a sweat. If you've made the switch to propane for its economy and safety, this is the tip that ensures you don't sacrifice cutting performance.

One of the standout features of this tip is its two-piece construction. Unlike standard acetylene tips, the GPN series separates into an inner brass piece and an outer copper sleeve. Why does this matter to a welder? Because cleaning tips is a part of life. With this design, if you get a flashback or clog the preheats with slag, you can pull the outer shell off and easily clean the splines on the inner member. This means less time fighting with tip cleaners and more time burning metal. It also means you aren't throwing away a tip just because it got a little dirty, saving you money in the long run.

Getting your settings right is key to a slag-free cut. For this Size 4 tip, you'll want to dial your oxygen regulator to about 45-50 PSI and your fuel gas to 8-12 PSI. This sweet spot gives you a cutting speed of around 8-11 inches per minute. The preheat flame is designed specifically for the burning characteristics of propane and natural gas, giving you enough heat to start the cut without washing out the top edge of your plate. This control is crucial when you are working on expensive stock or preparing a beveled edge for a weld joint.

Whether you are doing demolition work, structural steel fabrication, or general repairs, the Victor 4-3-GPN delivers the consistency you expect from the Victor brand. It works equally well on a hand torch or a track burner, making it a versatile addition to your torch kit. Don't settle for generic knock-offs that sputter and pop; stick with the genuine Victor Series 3 GPN for smooth, professional cuts through thick plate steel.
