What does a Single Layer Nozzle do?

• High Gas Flow Rate: Because it lacks a secondary inner layer, it allows high-pressure gas to flow into the kerf continuously and at a high flow rate.

• Slag Removal: Quickly ejects the molten metal from the bottom, creating a burr-free and smooth cutting edge.

• Application Area: Used in Air cutting and Nitrogen cutting—it is the preferred nozzle type in air cutting to minimize burrs.

What does a Double Layer Nozzle do?

• The double layer nozzle is specially designed for cutting sheets (such as ST37, ST52, DKP, HRP, and HARDOX) using oxygen assist gas in fiber laser cutting machines.

• Thanks to its nested, dual-body structure, it reduces gas velocity and prevents turbulence (eddies), delivering a calm, stable, and laminar oxygen flow to the cutting area. This controlled flow:

  • Prevents uncontrolled burning of the sheet metal and corner melting.

  • Ensures the cutting kerf remains clean, vertical, and smooth.

  • Eliminates the risk of blowout or boiling, offering a stable and high-precision cutting performance at low pressures (0.5 – 2.5 bar).
