Adjustment sequence for focus, speed, gas pressure, and nozzle, plus key points for nitrogen cutting.

Dross mostly appears on the bottom surface, indicating that molten metal has not been fully blown away.

Adjustment sequence:
1) Focus: Lower the focus first (-1 to -2 mm) and observe whether dross decreases.
2) Speed: Reduce speed appropriately, but too slow a speed leads to excessive heat input and more severe dross.
3) Gas pressure: Insufficient nitrogen cutting pressure is a common cause; for 6 mm plate, 14-16 bar is recommended; excessive pressure creates turbulence.
4) Nozzle: Check concentricity and orifice diameter; nozzle wear causes airflow deflection.
5) Material: Confirm the surface is free of oil and rust, otherwise absorption is affected.

Change only one parameter at a time and record cut quality to avoid mixing multiple variables.
