Installation Instructions

1. Ensure the laser machine is powered off and cutting head is cool
2. Remove the standard nozzle from the cutting head
3. Inspect the nozzle seat — ensure it is clean and undamaged
4. Install the D28 supersonic pressurized nozzle, ensuring proper thread engagement
5. Tighten firmly but avoid over-torquing to prevent thread damage
6. Set appropriate gas pressure — supersonic nozzles require higher assist gas pressure than standard nozzles (typically 10–20 bar for N2/O2)
7. Perform a test cut to fine-tune gas pressure and focus position
