While nominally equipped with 100 W laser tube, SID XL 1390 supports 150 W upgrade option that utilizes CO2 laser tube technology. This enables cutting through thicker materials as well as accelerated engraving. Latter refers to straight lines and piercing times at start of cut. Upgrade also promotes smooth surface finish when cutting thicker materials. Sensors and precision laser cutting head ensure precise engraving of fine details, such as 2 mm dia circles.
