Features: & 12304;New Eye Protection Design& 12305;: The laser protective cover plays a very good role in protecting your eyes. You and the people around you can watch laser engraving without wearing goggles. Reduce the cost of your goggles and the inconvenience of wearing goggles. & 12304;Solid and Easy Installation Structure& 12305;: The full-metal structure design makes the machine more solid and durable, and improves the accuracy of engraving. The whole structure is designed for quick assembly, and the assembly can generally be completed within 10-20 minutes. & 12304;Upgraded Fixed-Focus Laser& 12305;: Engraving can be done without adjusting the focus; The new laser can combine both precision engraving and high-energy cutting at the same time. The laser power of the fixed-focus laser is more stable than the zoom laser. & 12304;Ultra-Fine Compressio n Laser& 12305;: Laser power is 4.5-5.5W, the high-power engraving is faster and more accurate. The ultra-fine laser focus area is reduced to 0.23mm^2. The high-density laser can easily cut 12mm thick wood and black Acrylic; can directly engrave smooth stainless steel metal and ceramics. & 12304;Intelligent Security Protection& 12305;: When the laser is in an abnormal state and continues to be irradiated, the laser will automatically stop to prevent fire; when the engraving machine is impacted by an external forc e, the laser will automatically stop to avoid danger (Customers can choose whether to use this function). & 12304;Extensive Compatibility& 12305;: The machine can be compatible with various mature engraving software, such as LaserGRBL, LightBurn, support Windows XP/7/8/10(LaserGRBL), and also support Mac system (LightBurn), engraving file format support NC, BMP, JPG, PNG, DXF etc. & 12304;Precision Scale Line Axis& 12305;: X-axis and Y-axis has precision scale lines, which is convenient for you to carry out quick length measurement. The 410x400mm large-area engraving interval can meet your various engraving needs. Widely used in metal(non-reflective or painted black), wood, plastic, paper, bamboo, leather, etc. & 12304;Integral Screw Rod& 12305;: The machine uses an integral screw rod instead of a combined coupling. The stepping motor and the screw rod are integrated, which makes the movement of the laser more precise and the coupling more durable. Specifications: Product Model: ATOMSTACK A5 Pro Frame Material Sheet Metal + Aluminum Profile Input Voltage: AC100-240V, 50/60Hz Output Voltage: DC12V, 3A Engraving Size: 410*400mm Carving Objects: All wood, bamboo, paperboard, plastic, leather, PCB board, aluminum oxide, non-reflective plating and lacquered metal. Cutting Objects: Cardboard, non-woven fabric, thin wood, acrylic material, thin plastic board. Laser Power: 40W Laser Output Power: 4.5-5.5W Wave Length: 455±5nm Engraving Accuracy: 0.01mm Focusing Method: Fixed focus laser, no need to focus Laser Safety Protection: When the laser is under control, the motor does not move and the laser lights up. If the user forgets to turn off the laser, the laser will automatically turn off after a period of exposure to prevent fire. Impact move will be detected ,and the machine will stop to avoid danger.
