Handheld Laser Marker for Large, Heavy and Fixed Objects

The Dato LM-H is a handheld fiber laser marking machine designed for large, heavy, fixed, or hard-to-move objects. Instead of moving the workpiece to a marking table, operators can bring the handheld marking head directly to the object.

It is suitable for permanent marking on machinery parts, metal structures, tools, pipes, vehicles, construction materials, nameplates, and industrial equipment. The LM-H can mark logos, QR codes, barcodes, serial numbers, text, and traceability codes on metals and selected plastics.
