OVERVIEW

Cut Thick and Dirty Steel with the Uniweld HPN-8

When you are staring down a slab of steel that is nearly a foot thick, you need a cutting tip that means business. The Uniweld HPN-8 is that tip. Designed for use with Propane or Natural Gas, this "Heavy Preheat" nozzle is a beast in the scrap yard or on the demolition site. We all know propane burns cooler than acetylene, which can make starting a cut on rusty or painted metal a headache. Uniweld solves this with the HPN series, which pumps out a massive amount of preheat flame to get your metal to kindling temperature fast, regardless of surface condition.

Why Choose a Two-Piece Tip?
Unlike single-piece acetylene tips, the HPN-8 uses a two-piece design. The inner brass part has splines that guide the gas, and the outer copper shell protects it. This design creates a recessed pocket at the end of the tip. Why does that matter? Propane needs that pocket to keep the flame stable. Without it, your flame would blow itself out every time you hit the oxygen lever. Plus, if you get some slag blowback, you can take the two parts apart and clean them out easily, saving you from having to toss the tip in the trash prematurely.

Massive Capacity for Big Jobs
This is a Size 8 tip. It isn't for sheet metal or light fabrication. It is rated for cutting steel between 8 and 12 inches thick. Whether you are processing heavy machinery, cutting risers in a foundry, or slicing up structural beams, this tip delivers the oxygen flow required to blow through thick sections cleanly. Because it fits standard Victor-style torches, it will likely slide right into the heavy-duty torch handle you already have in your truck.

Save Money on Fuel
Switching to propane with the HPN-8 doesn't just give you a durable tip; it saves your wallet. Propane is significantly cheaper than acetylene and much more stable to transport. With the heavy preheat design of the HPN-8, you don't have to sacrifice start times to get those savings. Equip your torch with the Uniweld HPN-8 and tackle the heaviest jobs with confidence and efficiency.

FAQ

The HPN-8 is designed for use with Propane or Natural Gas (LPG). It should not be used with Acetylene.

A size #8 cutting tip is generally rated for cutting steel thicknesses between 8 inches and 12 inches.

Yes, the Uniweld HPN-8 is compatible with Victor-style cutting attachments and torches, specifically those designed for heavy-duty applications (like the 300 series).

Heavy Preheat means the tip is designed to deliver a higher volume of fuel and oxygen for the preheat flame. This helps compensate for the lower temperature of propane and allows for faster starts on dirty, rusty, or painted metal.

You can separate the outer copper shell from the inner brass member. Clean the splines on the inner member with a soft brush or cloth and ensure the seating surfaces are free of debris before reassembling.

While it has a heavy preheat flame, it is primarily a cutting tip. For dedicated heating applications, a rosebud heating tip is more efficient, but the HPN-8 can provide substantial localized heat for starting cuts.

The recess protects the flame from blowing out (flame standoff) and creates turbulence to ensure proper mixing of the propane and oxygen, which burn at a different velocity than acetylene.

For a size 8 tip, oxygen pressure is typically very high (often 65-75+ PSI depending on the specific cut depth) and fuel pressure is generally around 10-15 PSI. Always consult the specific tip chart for safety.
