5. Preparation for use
Read and make sure you have understood all safety warnings and precautions in this
manual before you use the induction heater.
Generator and induction heater
The induction heater is designed for the power supply printed on the label and works
without damage at voltages up to 10 % above the specified value.
1. Generator: Some portable generators, and in particular cheap devices, which generate
4 kW or less, are unregulated and can exceed the voltage by more than 20 % which will
damage the device and void the warranty. If you are unsure with regard to the electrical
generator that powers the induction heater, have an expert measure the generator voltage
with a digital voltmeter. Measure the voltage when the generator is warm and without load.
The voltage of some generators can be reduced by reducing the engine speed.
2. Induction heater: DC/AC converter operation: Use only 1.8 kW or larger sine
wave inverters.
6. Using the induction coils
Induction coils are used to heat nuts, fasteners, frozen door hinges, exhaust manifold
bolts, truck frame bolts and sensors (O2).
The life of the induction heating coil can be extended by only heating objects until
the seized rusted conncetions are broken. The insulation of the coil will eventually burn
through, if you hold it directly to hot nuts.
Loosening corroded, rusty and "fseized" screws and nuts ≤ M18
1. Carry out section 5, "Preparation for use".
2. Switch on the induction heater.
3. Position the coil to it surround the seized nut for 2 seconds only, try to release the nut
with a spanner or a socket wrench. If this is not possible, use the coil for a further 2 sec-
onds and then try again with the spanner.
There is usually no reason to heat a nut until it glows in order to free it from the corrosion
binding it to the bolt.
