The working principle of the heater:
1. Short-circuit heating: the host is a transformer with a special structure, and the movable yoke is used to directly pass through the sleeve bearing or other heated workpieces. When working, turn on the power supply of the host machine, and the workpiece (equivalent to the secondary winding) is induced to generate a short-circuit current and be heated.
