How to choose a suitable nozzle?

Before we get started,  We need to understand the difference between the single-layer nozzle and the double-layer laser nozzle of the laser cutting machine.

Firstly, the single-layer laser nozzle is used for melting cutting, that is, using nitrogen as the auxiliary gas to cut stainless steel and aluminum plates, etc., and the single-layer laser with a rule of 1.4 to 3.0 nozzle.

Secondly, double-layer laser nozzles are generally used for oxidation cutting, that is, oxygen is used as auxiliary gas for cutting carbon steel, and double-layer laser nozzles with specifications of 1.5 to 3.0 are used.
