The power settings that work best for LaserBond 100 will vary depending on the type of laser being used. For example, with a 30 watt CO2 laser, marking on stainless steel requires 100% power and 50% - 60% speed (500 – 600mm/sec) with 500 – 600 dpi. Marking on aluminum requires 100% power at a much slower speed of 5% - 10% (50 – 100mm/sec) and 1000 dpi with the same laser. A more powerful laser will be able to make the same mark using faster speeds and/or a lower percentage of power. Also, aluminum, brass, copper and other soft, heat conductive metals will require higher powers and slower speeds. These metals will conduct heat away from the marking surface more quickly than steel or other hard metals, thus requiring more overall laser power on the substrate surface for a longer time in order to make a satisfactory mark. Power settings will vary depending on the laser used and the substrate material being marked, so refer to the suggested laser settings on the enclosed instruction sheet or on the www.laserbondingtech.com website. Some experimentation will be necessary in order to achieve the best results.
