14Z77 - Oxweld 1515-6 Propane/Natural Gas Cutting Tip | Size 6

Get Clean Cuts with the Oxweld 1515-6 Propane Tip

If you are running Propane or Natural Gas on your rig, you know that using the right tip makes all the difference between a clean drop and a jagged mess. The Oxweld 1515-6 (Part # 14Z77) is the go-to cutting tip for welders and fabricators needing to slice through heavy plate. Rated for 4-inch steel, this Size 6 tip delivers the heat and power you need to punch through thick stock without wasting time waiting for the puddle to form.

Why choose the 1515 series? It’s all about the two-piece design. Unlike standard acetylene tips, this nozzle has a separate inner part and an outer copper shell. This setup creates a stable, heavy preheat flame that stays lit even when you crank up the oxygen. Propane burns cooler than acetylene, so you need that extra preheat volume to get the steel hot enough to cut. The 1515-6 delivers exactly that, giving you fast starts and smooth travel speeds. Plus, the copper shell is tough enough to handle the heat and abuse of a busy shop or scrap yard.

Maintenance is a breeze with these tips. If you get some slag blowback or the tip starts acting up, you can pull the outer shell off and clean the inner splines easily—no more fighting with tiny drill bits that snap off inside the holes. This tip fits all standard Oxweld torches (like the classic C-32 or the heavy-duty hand torches), so it drops right into your existing setup. Whether you are scrapping heavy machinery, cutting risers, or profiling thick plate, the Oxweld 14Z77 gives you the reliability and cut quality professional welders demand.
