induction heating Induction Heater JH400
JH400 is a mobile induction heater which is
used to heat metallic parts on vehicles without
damaging nearby parts. The induction heater
can produce heat without physical contact and
without an open ame. The heater ensures
minimal dismantling of nearby heat sensitive
parts.
JH400 has a versatile working range. For
example, the heater is used for:
• heating rusted wheel bolts and nuts.
• heating rusted door hinge pins.
• heat shrinking steel and aluminium panels
during repair.
• heating of rusted exhaust manifold ange
bolts in hard to reach places.
• heating of rusted bolts and nuts on the
suspension or steering.
• easy removal of underseal and PVC
coating.
JH400 is principally designed to heat
all magnetic materials (conductors) by
concentrating a powerful magnetic eld at
the head of the inductor. But, the heater also
works well on aluminium. The magnetic eld
alternates at a frequency of approximately
18-40 kHz. The magnetic eld creates eddy
currents in the material, and the electrical
resistance creates heat in the metal.
Since heat is created by electronic losses and
radiation from the work piece, JH400 has an
internal cooling system with water as cooling
agent. The water circuit cools the high power
electronics, cables, inductor handle and
inductor. As soon as the trigger is pressed, the
water pump starts pumping the cooling water in
the heater.
WARNING! All transportation of
JH400 must be done with the
water tank empty or the tank is
placed out side the JH400.
This is due to the risk of water
leakage and possible structural
damage of the chassis of JH400
from living weight of the water.

heater on an unstable or
uneven ground. The heater
might fall, causing personal
injuries or serious damage to
the heater.
WARNING!
All electrical modications
must be made by a qualied
electrician.
Risk for electrical shock.
WARNING!
Do not ll the water tank with
anything but Decalcied water
mixed with High-Tech uid.
Improper handling may result in
personal injury and/or damage
to the equipment.
WARNING!
Do not touch any object that
has been near the inductor
without ensuring that it has
cooled off.
WARNING!
Do not touch the inductor while
it is activated due to strong
magnetic eld and heat. Risk
for personal injuries.
WARNING!
When using the heater, the
working area should be cleared
from combustible items to
prevent these items from being
ignited.
WARNING!
Make sure that you know
where the re extinguishing
equipment is. Risk for injuries.
WARNING!
If not removing paint or other
chemicals before heating,
use a suction fan to remove
unhealthy fumes. Risk for
personal injury.
WARNING!
When operating, servicing
or working in the immediate
area around JH400, the user
should not wear or use metal
objects such as watches, rings,
keys etc. Otherwise, these
objects could be heated by
the magnetic eld from JH400
which might cause burning
injuries.
WARNING!
Most service must be carried
out by JOSAM AB service
personnel and service support.
Risk for electrical shock.
WARNING!
Never remove any covers
or perform any work to the
induction heater without
unplugging it from the wall
outlet. Wait for ve minutes.
