Mark Allen says
This 1.5 kW induction heater is intended for controlled, localised heating in vehicle repair and general workshop work. I use it for freeing seized nuts, bolts, hubs and smaller components, as well as removing bonded parts, heating exhaust sections and curing adhesives or sealants.
The main advantage over a flame is that heat can be applied to the conductive metal without introducing an open flame near wiring, fuel systems, paint or trim. Coil selection matters: the coil should suit the shape and size of the component so the heat is concentrated where it is needed. It operates from a standard 230 V supply and is suitable for lighter repair work, with the fan cooling and limited duty cycle taken into account during repeated jobs.
A common mistake is holding the coil too far from the work or leaving it in one position for too long. That can reduce efficiency or overheat adjacent material. Keep the coil moving where appropriate, monitor the part temperature and protect nearby components. Used with the correct coil and sensible heating intervals, it is a reliable way to make difficult removal work quicker and safer.
