2. Safety Information
Operating a laser engraver requires strict adherence to safety protocols to prevent injury and damage. Please read and understand all safety warnings before operating the machine.
- Laser Class: This device is a Class 1 laser product (IEC60825-1:2014) with a power output of 2.161mW. Despite being Class 1, direct exposure to the laser beam can cause severe eye damage.
- Eye Protection: The transparent window is tinted to provide eye protection during operation. Always monitor engraving progress through this window. Never look directly into the laser beam.
- Automatic Power Cut-off: The machine is equipped with a safety mechanism that automatically cuts off power to the laser when the lid is opened during operation.
- Emergency Stop: An easily accessible emergency stop button is provided. Press this button immediately in case of any malfunction or emergency.
- Ventilation: The integrated air assist system helps to blow away smoke, dust, and sparks generated during engraving and cutting. Ensure proper ventilation of your workspace to dissipate fumes.
- Material Safety: Only engrave or cut materials that are safe for CO2 lasers. Avoid materials that produce toxic fumes or are highly flammable when exposed to laser energy.

Key safety features including the laser tube, transparent protection cover, front & rear pass-through, built-in air assist, emergency stop, and movable wheels.
3. Setup
Follow these steps to set up your VEVOR 80W CO2 Laser Engraver for the first time.

4. Operating Instructions
This section outlines the basic steps for operating your laser engraver.
- Power On: Turn on the main power switch of the engraver.
- Material Placement: Place your material securely on the honeycomb bed. The spacious 20 x 28 inch (500 x 700 mm) working area accommodates various project sizes. The honeycomb structure ensures high structural stability for your materials.
- Focus Adjustment: Adjust the laser head focus according to the material thickness. The intelligent laser head ensures high cutting precision and smooth, burr-free incisions.
- Red-Dot Pointer: Utilize the red-dot pointer to indicate the engraving point and effectively frame the project size on your material before starting the job.
- Software Operation:
- Prepare your design in your chosen graphic software (LightBurn, CorelDRAW, AutoCAD).
- Configure laser parameters (power, speed, passes) based on the material type and desired outcome.
- Transfer the design to the engraver via USB or network.
- Start Engraving/Cutting: Initiate the job from the digital control panel or your software. Monitor the process through the transparent safety window.
- Material Capabilities: The machine can cut materials up to 0.59 inches (15 mm) thick in one pass and engrave on a wide range of materials including wood, acrylic, cardboard, glass, leather, stone, and fabric at speeds up to 19.7 ips (500 mm/s). The linear guide rail ensures smooth curve cutting.
- Front and Back Pass-Through: For larger materials, utilize the front and back pass-through doors to extend your working capabilities.
