Oxweld 1566HS Size 4 Machine Cutting Nozzle for Propane/Natural Gas

Maximize Your Machine Torch Potential with Oxweld

When you are running a burning table or a track torch, the quality of your consumables dictates the quality of your output. The ESAB Oxweld 1566HS Size 4 Cutting Tip is built for welders and fabricators who need reliable, high-speed performance using Propane or Natural Gas. This isn't just a standard tip; it is a high-speed (HS) variant designed to push your machine's travel speed faster while maintaining a clean kerf. Capable of slicing through 4-inch thick steel plate, this Size 4 nozzle is a workhorse for structural steel yards, shipyards, and heavy equipment manufacturing.

Switching to alternate fuels like Propane often saves money on gas, but it can sometimes lead to slower preheat times compared to Acetylene. The 1566HS solves this with its High Preheat design. The heavy preheat flame puts a tremendous amount of heat into the plate immediately, blasting through rust and scale so you aren't waiting around for the puddle to form. This means faster piercing and less time sitting still. Once you are moving, the tip sustains cutting speeds of 7 to 13 inches per minute, helping you clear the table faster and get parts to the fit-up crew sooner.

The two-piece design is practical for the shop floor. We all know that blowback and slag happen. With a two-piece tip, you can pull the insert out of the shell to clean the splines properly, extending the life of the consumable. The heavy copper and brass construction withstands the reflected heat from 4-inch plate cutting, resisting deformation and tip bell-mouthing. It fits standard Oxweld style machine torches, making it a drop-in upgrade for your existing setup.

Dialing in your pressures is key for this tip. You will want your cutting oxygen up around 90 PSIG to get that deep, penetrating stream that clears the kerf cleanly. Fuel pressure runs low, around 5-10 PSIG, which is typical for alternate fuels. By optimizing your gas settings to the manufacturer's specs, you get a smooth face on the cut edge, reducing the amount of grinding needed before welding. If you are cutting heavy plate with propane or natural gas, the 1566HS Size 4 is the tip that keeps your production line moving.
