The LaserBeam and any other laser device can cause harm to you or others. Ensure that you follow these safety guidelines

Never let the laser run unattended

Ensure that you have a fire suppression system such as a fire extinguisher nearby in case of a fire. Never leave your laser unattended. Ensure that your laser is turned off when not in use.

Ensure proper ventilation

Use the laser in a well-ventilated environment. Fumes and particulates from cutting or engraving can be harmful. We recommend having a fume extraction system or having an open door or window to provide ventilation.

Wear Eye Protection

Wear compatible laser safety goggles or glasses. Not wearing appropriate eye protection may cause permanent eye damage.

The FDA recommends no more than 5 mw to avoid eye damage. The glasses sold are rated for 0.007 mw or over 700 times better at reducing laser exposure significantly more than the minimum requirement.

Cut only laser safe materials

Never cut materials that can generate toxic fumes or are dangerous to cut, such as

  • PVC
  • ABS
  • Vinyl
  • Fiberglass

Integrated Driver Safety Features

Key Switch: This key is needed to enable the laser. Once the key switch is turned on, the laser is enabled and the key cannot come out. Only when the driver is off can You can only remove the key.

Remote Interlocks: This allows for additional switches to be added to the laser. An E-stop or other system can be implemented to shut the laser down in the case of an emergency.

Power Fault Protection: If the driver ever loses power the laser will turn off. In case of a power outage, you can have peace of mind knowing that the laser is off whenever power returns.

Emission Indicator: The small LED on the LaserBeam driver will notify you if the laser is on. This becomes useful if operating outside the visible light spectrum
