What gas are used in the machine?
As we all know, fiber cutting machine must work with gas, it generally uses three kinds of gas: oxygen, nitrogen and air.
Long ago, oxygen was the most common gas used in laser cutting.After research found that nitrogen has a better cutting effect, can make the edge of the cutting material more clean and bright, of course, the three kinds of gas in the cutting material has different applications.
When cutting carbon steel, generally use air or oxygen, oxygen effect is better
When cutting stainless steel, nitrogen is used to cut the edge of the sample with black air, and oxygen is cut with yellow
An auxiliary gas is injected at the nozzle to supplement the process.This is an exothermic reaction — a chemical reaction in which energy is released by light or heat.Introducing nitrogen, oxygen, or air is more conducive to heat transfer than just using light beams
