Profile: Southeast Cutting Machinery Corp. specializes in providing cutting machinery and fabrication equipment. Carbon dioxide lasers are the powerful continuous wave lasers available. Because CO2 lasers work with a wide variety of metals, they are most often used in welding and automotive industries. Fiber optic laser uses less energy than the CO2 laser while maintaining the same or sometimes higher level of performance. The laser is carried along an optical fiber and provides a wavelength with a beam density and improved focus for high-speed laser precision cutting. Our CNC plasma cutters combine computer technology with plasma cutters to create a precise system capable of complex processes. The CNC plasma cutters allow a computer to control the torch to produce a clean, sharp cut.
