[0002] An electric thermal cutter is a device that uses heating wire to generate heat to achieve the purpose of cutting. It is mainly used to cut non-metallic foam materials. The working principle of the electric thermal cutter is based on the resistance heating property of the heating wire. When current passes through the heating wire, the resistance of the heating wire generates heat, causing the heating wire to heat to a sufficiently high temperature, thereby melting or oxidizing the target material and achieving cutting.

[0003] Existing electric heating cutters fix the heating wire and cut by pushing the material over the heating wire. This method limits the cutting range of the heating wire and is affected by the length of the heating wire. The heating wire length cannot be changed for materials of different sizes, and large pieces of material cannot be cut. Utility Model Content
