Possible causes
- Improper gas supply: The assist gas suffers low pressure or poor purity, affecting the efficiency of slag removal and the laser cutting capability.
- Power attenuation: The reflector is contaminated or the optical path is misaligned, resulting in power attenuation.
- Incorrect focal position: The focus setting is wrong, leading to reduced energy concentration on the material surface.
Detailed procedure
