The Widlaser C-series is the professional line for laser cutting and engraving, aimed at several industries. The series is available in four models – C500, C700, C900 and C1000 – where the number roughly reflects the size of the work surface in millimeters. The work surfaces range from 700 × 500 mm (C500) up to 1,600 × 1,000 mm (C1000), with a height-adjustable table up to 150–200 mm depending on the model. The standard power is between 30 Watt and 100 Watt.

All machines in the series have the CleanProtect function with dust and smoke-protected components, autofocus, smoke extraction, dual air pressure system and cutting tables with honeycomb pattern or removable blades. Options include a CCD camera, round engraving for cylindrical objects (e.g. glasses, bottles and thermoses) and software from Lightburn or Fiery Engravelab. The C-Series is a cost-effective choice for professional users who want proven CO2 technology in a robust and compact machine.
