INTRODUCTION
General information
JH1500 is a mobile induction heater, which is
used for heating up metal parts on vehicles
without damaging nearby parts. The induction
heater produces heat without physical contact
and without naked ames. Using the induction
heater makes it possible to leave nearby,
sensitive parts in place.
The are many application areas for the JH1500.
For example, the induction heater can be used
for:
• Heating nuts and bolts that have rusted in
place
• Heating hinge pins that have rusted in place
• Heat‑shrinking steel and aluminium panels
when making repairs
• Heating, for example, couplings to exhaust
systems that have rusted in place and
places that are difficult to reach
• Heating screws that have rusted in place
• Nuts on the suspension or the steering
• Simple removal of underbody protection and
PVC coating
• Frame straightening
Induction heater JH1500
The JH1500 is designed to heat metals, by
concentrating a powerful magnetic eld at the
inductor head. The induction heater also works
well on aluminium. The magnetic eld alternates
at a frequency of ca 14‑30kHz. The magnetic
eld induces eddy currents in the material, and
the electrical resistance produces heat in the
metal.
Since heat is created due to electrical losses
and radiation from the plates, JH1500 has an
internal cooling system, using water as the
coolant. The water circuit cools the high‑power
electronics, cables, induction handle and
inductor. When the machine starts, the water
pump begins to pump the cooling water in the
induction heater.

Safety devices
When the induction heater is in use, the
inductor, cables, electronics and transformer
can frequently become very hot. To protect
the induction heater from overheating, it is
cooled continuously when in operation. The
induction heater is cooled all the time by
water that circulates through the inductor. The
water begins to circulate when the machine is
started. A sensor detects the water ow and
trips the induction heater if the ow is blocked.
The JH1500 must be connected to earth.
It has an inbuilt residual current breaker to
protect the user in case of a ground fault. It
also has an automatic fuse, which trips if the
current exceeds 32 A (for JH1500‑400V) or
63A(forJH1500‑200V).
In case the JH15000 would get overheated,
the overheating protection automatically
disables the heating function to protect the
machine and its electronic parts. However, the
cooling system continues to cool the machine
to make it ready for operation again.
The inductor handle is insulated to protect the
user from electric shocks.

2. electrical section
3. hose packet with inductor
During heating, a powerful magnetic eld is
concentrated in the inductor. The magnetic eld
alternates direction and induces eddy currents
in the material, which gives rise to heat. Since
intense heat is created in the work piece and
inductor, cooling water is used for cooling the
machine and its electronic parts. The control of
the cooling system is totally automatic.
The connection cable provides the machine's
electrical section with current, which in turn
power supplies the hose packet, inductor and
cooler section. The cooling section controls the
temperature of the components by circulating
cooling water in the hose packet, inductor and
a cooling block in the electrical section.

USAGE
General information about induction
Induction heaters work with low voltages and
high currents in order to create a magnetic
eld. The magnetic eld is concentrated to
the eld amplier. When the tip is placed
against iron or another magnetic material, the
magnetic eld is short‑circuited and heat is
formed.
Information about heating
It is important to control the temperature
of the heated work piece, if quality is to be
maintained.
The human eye is inuenced by the ambient
conditions. The illumination changes how the
eye experiences colour. Therefore, the heated
work piece should be examined in daylight.
The colour temperature scale, to the left,
simplies visual control and, at the same time,
the stepwise presentation of temperature
improves the accuracy during heating.
