If you require higher wattage or the ability to mark directly on to metals, the PLS series may be the perfect fit for your applications. The dual laser CO2 models offer a maximum of 150 watts. The PLS6MW multi-wavelength series allow you to swap quickly between CO2 and Fiber laser sources. The Fiber laser source is a great option for high quality direct marking on to metals as well as cutting of thin guage metals. Fiber Laser Systems will also produce nice contrast markings on many materials where the CO2 laser source will not.
