Reportedly, the unit requires minimal preventative maintenance and entails no consumables costs. The marker is air cooled for temperature regulation and employs diode technology specifically designed for high reliability and long lifetime. The system can be used in conjunction with the company's WinLase laser marking software. Laser powers include 10, 20, and 50 watts. Field sizes range from 70 mm to 280 mm square, while spot size selection ranges from 22 mm to 60 mm.
