An induction heater is a multiuse tool that can be used to heat metallic objects quickly and locally. It relies on induction, in which a coil can induce eddy currents within conductive material that is placed inside of the coil. This requires a very quickly-oscillating alternating current in order to induce the eddy currents that heat the metal. Induction heaters have many practical industrial applications, and they can also come in handy for hobbyists who don’t want to work with open flames or other heat sources. If you have a need for one, you can follow DIY KING 00’s tutorial to build your own affordable 2000 watt induction heater.
