INDUCTION HEATER - KMi
2INTRODUCTION
This device generates alternating current of high frequency. The current passing through a heat-
ing coil creates an alternating magnetic field which by using the principle of electromagnetic
induction vibrates electrons inside the heated material. The energy of moving electrons is dissipated
as heat, which heats the metal in the work field of the instrument. The more easily magnetizable
material, the more heat it generates. The device heats easily ferrous metals and their alloys, but has
no effect on glass, plastics, wood, textiles and other non-conductive materials.
2.1 INDUCTION HEATING PRINCIPAL
Induction heating is the process of heating an electrically conducting object (usually a metal) by
electromagnetic induction, through heat generated in the object by eddy currents. An induction
heater consists of an electromagnet, and an electronic oscillator that passes a high-frequency
alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates
the object, generating electric currents inside the conductor called eddy currents. The eddy currents
flowing through the resistance of the material heat it by Joule heating. In ferromagnetic (and
ferrimagnetic) materials like iron, heat may also be generated by magnetic hysteresis losses. The
frequency of current used depends on the object size, material type, coupling (between the work coil
and the object to be heated) and the penetration depth.
An important feature of the induction heating process is that the heat is generated inside the
object itself, instead of by an external heat source via heat conduction. These objects can be heated
very rapidly. In addition there need not be any external contact, which can be important where
contamination is an issue. Induction heating is used in many industrial processes, such as heat
treatment in metallurgy, Czochralski crystal growth and zone refining used in the semiconductor
industry, and to melt refractory metals which require very high temperatures. It is also used in
induction cooktops for heating containers of food; this is called induction cooking.

3.2 ELECTRICAL SAFETY RULES
This is a safety class I device, which may be supplied with power only from the power
outlet with a protective conductor, which must be connected to the device as first and
in any case must not be interrupted /e.g. by an extension cord/. Any interruption of the
protective earth conductor, or its disconnection will cause a potential electric shock
hazard that can cause injury. Make sure that the device /device chassis/ is properly
grounded.
Do not twist or sharply bend the power cord, as it may damage the internal wiring.
Never use KMi heater X175 if the power cord shows any signs of damage. Keep the
power cord away from heat, oil, sharp edges or moving parts. Never repair the power
cord if damaged, the power cord must be replaced. Damaged cords create a risk of
electric shock.
It is necessary to tight the screws for coil /9/ properly after every changing. Free screws can harm
damages on the machine and sparking which causes the overheating of the contacts – the working
current is 300A!!! The material of the heating coil is being expanded and contracted while working.
Therefore it is necessary to check all the time the tightened of the screws on the handle.
I tis forbidden to use the device if the cover, handle, coil or cable is damaged or not in a 100% fit –
there is a danger of injury or death by the electrical current or a fire. Keep the cables, working coils
and the device itself off the another heat devices, acetone, colours, dope, hydroxides, the other
chemicals, sharp edges or moving parts. The red isolation to the handle /4/ and the isolation of the
coils /10/ is resistant for the oils, acids only for a little. If the cord, isolation or the isolation of the
working coil is damaged, must be replaced only by the manufacturer or responsible person trained by
the manufacturer to prevent any injury or harm.
The manufacturer and the seller are not responsible for the consequences of an inappropriate usage
of the device written in this manual.
Do not touch the working coil while in process of heating. Do not switch on the machine without the
working coil. There are high current peaks while the machine is ON without the working coil and
therefore the device can be damaged by that because of the damaging the overvoltage protection.
Do not use the working coils with damaged isolation or no isolation.

Before usage of the device, check the incoming cable, handle and the handle cable to assure that
they are not damaged.
1. Disconnect the device from the electric network and loosen the screws on the handle. (9.).
2. Insert the working coil into the holes /handle 2/ in the clamping holder of the coils and
tighten the locking screws on the sides/9/.
3. Connect the supply cable of the device into a properly grounded standard socket ~230V,
50/60Hz and turn on the device using the main switch. Before turning on, make sure that the
handle is laid in a safe place and that the heating button is not pressed down/8/.
4. Attach or put the working coil on the material you want to warm up and press the button on
the handle. Heating remains activated during the pressing of the button - do not exceed the
operating cycle of 1,5 minutes of heating and 1,5 minutes of cooling.
After finishing the cycle, release the button on the handle /8/ and remove the heating coil/10/ from
the heated material.
While working with the KMi heaterX175 slowly move with the working coil to prevent the sticking to
the heated material. You can hear a little buzz during the operation or small vibrations which is
absolutely normal features of the induction procedure.
Always check the tightened of the working coils.
NOTE: During heating there should be a gap of around 3-5mm between the coil and
the heated material to avoid excessive wear of the heating coil. A gap larger than 3-
5mm decreases heating efficiency and extends the heating time
After finishing heating, place the handle with the heating coil in a safe, inflammable
place until the heating coil is completely cooled. Then turn off the device using the
main switch and disconnect it from the electric network.
ATTENTION: The coil and the heated object can reach a high temperature and/or
cause burns or result in fire.
