6 Safety Tips for Using Wood Laser Engraver
  • Wear Protective Gear: Use laser-specific safety goggles to protect eyes from the intense beam.
  • Secure the Work Area: Keep flammable items away and ensure proper ventilation or use a fume extractor to manage smoke, as highlighted in Facebook laser groups.
  • Wear a Mask: Use a gas mask to filter harmful gases and aerosols released during cutting, even with fume extractors.
  • Have a Fire Extinguisher Ready: Keep a dry powder or CO2 fire extinguisher handy, learn basic burn treatment, and clean the machine to prevent fires from dust buildup.
  • Clean the Lens Regularly: Regularly clean the focusing lens to avoid damage from smoke and dust, ensuring accuracy and longevity.
  • Read the Manual: Understand the diode laser’s power (5W-40W), compatible materials, and avoid toxic materials like PVC. Familiarize yourself with the emergency stop button.
