The GS-CE laser cutter has a full enclosure design that surrounds the entire cutting area, thus protecting the operator against laser radiation, as well as other injuries caused by small waste pieces. The working platform is designed with a hollow structure, which protects the operator from heat radiation, and also reduces the heat effect on the fiber laser cutting machine to improve its durability and stability. This fiber laser cutter is suitable for all sheet metal cutting requirements or sheet metal parts with specific heights.
