Before the Investment:

Before adopting our equipment, the factory mainly relied on air cutting for 12–40 mm carbon steel plates on

high-power laser systems. This often resulted in oxidized cut surfaces, rough edges, and heavy slag adhesion,

which negatively affected subsequent welding and painting processes. In addition, limited cutting speed and

increased post-processing workload restricted overall production efficiency.

After the Investment:

After investing in our FCP nitrogen generators and switching to a 94%–96% N₂–O₂

mixed gas supply, cutting performance improved significantly. Cut surfaces became clean and oxidation-free,

slag was greatly reduced, and both cutting speed and stability were enhanced. High-power laser systems

were able to operate at optimal performance, resulting in higher quality and improved production efficiency.

FCP Series Products Introduction: 

Mixed gas cutting employs a specific ratio of nitrogen-oxygen mixture as the laser assist cutting gas, leveraging

the advantages ofeach component gas (nitrogen for high-speed cutting and oxygen for burr-free cutting) by

combining them into a single cutting stream.This method enables rapid cutting with minimal burrs, significantly

improving the cutting quality for medium-to-thick low-carbon steeland aluminum alloys while achieving higher

cutting speeds than pure nitrogen. The burring issues encountered when using purenitrogen or air cutting a

are minimized or eliminated.

Advantages of Mix-Gas Cutting： 

● Improves cutting quality of ordinary steel, reducing burrs to <3% of material thickness.

● Higher surface finish compared to air cutting.

● Significantly increases cutting speed compared to oxygen cutting of high-power medium-thick carbon steel plates.

● Offers a cost advantage compared to liquid nitrogen cutting.

Fine Cutting VS Air Cutting vs O2 Cutting

Application
