laser works by exciting the molecules of a carbon dioxide gas mixture.
To engrave, the beam is focused through a lens. The intensive beam can vaporize
the surface of the material leaving an engraved image or, in some cases, cutting
through the material.
Safety
The safety rating of Class 1 by CDRH means that the laser beam is enclosed in a
cabinet and has safety interlock mechanisms to protect the operator from
injury. While when a class 1 laser system equipped with a red dot pointer which
allows you to position laser beam, the safety rating turns into Class 3a due to the red
beam is laser light. A few extra safety precautions; namely,
avoid placing your eyes
in the red beam path,
is required.

Precaution
1. Do not attempt to modify or disassemble the laser system at any time.
2. Wear appropriate safety goggles especially when engraving with mirrors
or coated metals such as enameled brass and anodized aluminum..
3. Good ventilation is required to remove odors and vaporized materials to the
outside of the building or structure. An exhausted system is recommended.
4. Invisible intensive laser radiation may cause physical burns or sever eye
damage. Always read the manual and caution labels carefully before operation.
5. Do not work with reflective metals, heat sensitive surfaces or other materials
that may produce toxic substances, such as PVC and Teflon.
6. A fire extinguisher should be available on hand at any time.
7. Never leave the machine unattended during operation.
8. Follow the recommendations for maintaining and cleaning your system. Not
only will this enable you to engrave efficiently, it will ensure that your
machine runs safely as well.
