The role of nozzles in cutting:
What are the roles of nozzles in cutting?
By adjusting the internal shape of the nozzle, the direction and pressure of the high-pressure airflow are controlled to maintain pressure between the workpiece and the nozzle.
Prevent splashes of molten material from reaching the interior of the cutting head, thus protecting the internal lens of the cutting head.
Provide a capacitance signal to the height control system to ensure stable operation of the system.
How to correctly select nozzles:
Types and characteristics of nozzles
Characteristics and applicable materials of single-layer nozzles
Generally used for melting cutting, with nitrogen or compressed air as the auxiliary gas.
Used for precision and high surface quality fine cutting.

Applicable materials:
For cutting stainless steel with nitrogen, single-layer nozzles are generally selected, with single spray 1.5 used for less than 2mm, and single spray 2.0 used for over 2mm.
Note: Specific applicability is subject to on-site process testing!
Characteristics and applicable materials of double-layer nozzles
Generally used for oxygen cutting, with oxygen as the auxiliary gas.
The airflow is re-converged and compressed, significantly improving cutting of carbon steel.
Applicable materials:
For cutting carbon steel with oxygen, double-layer nozzles are generally used, with 1.2/1.5 for below 3mm and 2.0/3.0 for above 3mm.
Note: Specific applicability is subject to on-site process testing!
