  • Page 44: Initial Testing

    4 Initial Testing Wear safety glasses during the entire test process! Always make sure the path is clear between the laser and its target. Never allow foreign objects between the laser and the material being engraved. Take care not to leave any part of your body in the laser path when it is in operation.

  • Page 45: Cover Shutoff

    4.2 Cover Shutoff Because of the risk of blindness, burns, and other injuries from direct exposure to the invisible engraving beam, this device shuts off the laser automatically when any one of its protective interlocks is triggered. Always make sure the path is clear between the laser and its target. Never allow foreign objects between the laser and the material being engraved.

  • Page 46: Water Shutoff

    4 Initial Testing 4.3 Water Shutoff Because of the danger posed by an uncooled laser tube, this engraver also shuts off the laser automatically when its sensors do not detect the correct water flow. You should test that the water shutoff functions correctly.

  • Page 47: Air Assist

    4.4 Air Assist Because of the danger posed by sparks during engraving and the risk of damage to the laser nozzle and focus lenses from fumes and debris, the pressurized air begins to blow from the laser head when the engraver starts engraving.

  • Page 59: Leather

    5.6.3 Leather When engraving leather products, generally use low to moderate power at high speed. Be especially attentive to the possibility of fire, as well as the dust produced in repetitive applications. 5.6.4 Metal CO ₂ laser engravers should not be used for marking, engraving, or cutting metal. They are best suited for working on coatings applied to a metal base, and care must be taken not to attempt to work on the underlying metal itself.

  • Page 60: Stone

    5 Typical Operation Sequence 5.6.8 Stone When engraving various kinds of stone, generally use moderate power and moderate to fast speed. As with ceramics and glass, be mindful of the dust created (especially for repetitive industrial applications) and take similar measures to ensure the safety of users and others in the work area. 5.6.9 Textiles When engraving textiles like cloth and fleece, generally use low power and fast speed.

  • Page 61: Wood

    5.6.10 Wood As with rubber, there is a huge variety of woods and testing your specific material is essential to get the best results. In general, wood with consistent grain and coloring engraves more evenly. Knotted wood produces uneven effects, while resinous wood produces greater edge contrast. Some soft woods like balsa, cork, and pine engrave well (albeit with low contrast) at low or moderate power settings and high speed.
