Handheld laser marking machines are primarily of the portable fiber-optic handheld type. Unlike traditional desktop fixed-position marking equipment, they break the limitations of workbench space. The main unit housing is paired with a draggable fiber-optic handheld marking gun, allowing operators to hold the tool head and directly mark large, heavy, non-disassemblable, or不便吊装上料的工件 on-site. No need to move the workpiece; permanent laser marking can be completed anytime, anywhere. Widely used in outdoor engineering, large equipment, pipeline tanks, and frame molds.
