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
Laser engravers that have the CDRH safety rating of Class 1 are required to have key safety
features such as an enclosed laser beam and safety interlock mechanisms designed to protect
the operator. In addition to the safety features of a Class1 machine, the LaserPro Mercury
has been equipped with a red guidance pointer. This red dot allows the operator to safely see
the focal point of the laser beam. It also gives Mercury the improved CDRH safety rating of 3R.
Precaution
1. The suitable temperature for working environment is 15 ~30 (60 ~86 )

. In an
appropriate and comfortable working environment, the working efficiency will be much
better.
2. Always wear certified safety goggles. Reflective materials such as mirrors, enameled
brass and anodized aluminum may reflect a portion of the invisible laser radiation.
This may cause sever eye damage if appropriate safety goggles are not worn.
NOTE:
Each LaserPro laser machine is equipped with a safety goggle, if you need
another one, please contact LaserPro for it or try to get one that meets the following
specification.
190-398 nm OD5+
10,600 nm OD5+
Visible light transmission: 92.9%
3. Do not attempt to modify or disassemble the laser system at any time.
4. Wear appropriate safety goggles especially when engraving with mirrors or coated
metals such as enameled brass and anodized aluminum..
5. Good ventilation is required to remove odors and vaporized materials to the outside of
the building or structure. An exhausted system is recommended.
6. Do not work with reflective metals, heat sensitive surfaces or other materials that may
produce toxic substances, such as PVC and Teflon.
7. A fire extinguisher should be available on hand at any time.
8. Never leave the machine unattended during operation.
9. 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.
Fire Precaution
1. When cutting materials that easily caught on fire, such as acrylic, wood or paper, it is
advised to have air compressor turned on to prevent flame.
2. If cutting table, or honey comb table, is used for cutting purpose, do not leave any
material underneath, as when material at top is cut through, the material at below will
be burned easily due to trapped heat.
