The high-frequency induction heater operates on the electromagnetic induction principle, with alternating current passing through the induction coil. This causes it to generate an alternating magnetic field that cuts the metal parts, causing eddy currents in the parts to generate heat. The frequency of the HF induction heating machine ranges between 30 and 80 kHz. It also has a heating depth of 0.5-2.5 mm and can be used to heat small and medium-sized parts.
