Currently, the use in the production process of induction heater is considered one of the most effective ways to achieve these goals in view of saving time and electricity. Induction heater is used in production processes such as smelting, heat treatment, hardening, brazing, etc. In its configuration induction heater contains a generator and an inductor. In the production process induction heater is used without direct contact with the heated product. The main advantages of induction heater can be assumed that the energy transferred from the heated product is transferred without heat loss, and the fact that it is possible to determine the depth of penetration of currents in the product. The effectiveness of performance with an induction heater depends, – firstly, on capacity of the installation of induction heating, since the power depends on the magnitude of the depth of the induction heating of the product. On the magnitude of power also depends on the weight of an induction heater, which ranged from 100 to 250 kg. Induction heater can be applied to different types of metals, with the heating of the metal will occur fast enough and excluded the probability that unwanted impurities into the metal..
