Induction Heater
An induction heater is exactly what it claims to be. It is a heating unit that works but utilizing powerful magnetic fields to heat a conductive body. There are three main components to an induction heater, the primary part being the coil. The coil is actually composed of many smaller coils – copper coils – wrapped around and around each other, and a central mandrel (a rod whose purpose is to be coiled by other metals and to keep them in the desired shape). The coil is the inductive unit, transferring the heat through from the power source to the working surface.
The power unit is of course the generator, the item that all induction heaters depend on, its function is to take in the power from the mains supply, and increase it to an average anywhere between 2-500 kW. The final component of any induction heater is the working surface or work head. This is simply an area of capacitors and transformers whose job it is to link the power from the other two units and allow the heater to function correctly.
