It features four operating modes: OFF for powering down, LOW for 3D-printed parts and thin plastics, HIGH for dense and thicker materials, and AUTO with automatic power adjustment for precise, continuous cuts lasting over 32 minutes. The tool comes with multiple compatible: #2 and #3 standard work for PCBs, wood, plastic,, carbon fiber, and leather; #4 is designed for fine 3D printing parts, paper, and fabrics; and #5 and #6 special shaped suit wood carving and thicker materials.
