Abstract: A portable wire cutting device for sampling a steel ingot includes a wire rack device, a driving system, and a multi-axis moving device. The wire rack device includes a first corner wheel, a second corner wheel, a transition wheel, a steering wheel, a first wire rack, a second wire rack, and a wire winding drum. The driving system includes a wire drum motor and a molybdenum wire, wherein the wire drum motor provides power driving for the operation of a cutting line; and the molybdenum wire is a closed molybdenum wire coil connected in an end-to-end manner, the molybdenum wire is wrapped around the first corner wheel, the second corner wheel, the wire winding drum, and an inner side of the transition wheel in a looping manner, and during operation, the cutting line performs wire cutting on an object by the molybdenum wire.
