Across
International IHE series induction heaters are designed with mid working
frequency between 30 and 100 KHz. Mid frequency hand-held induction heating
machine is the newest hand-held heating model. It is excellent for copper pipe
welding due to the design of its 3-5 meters extended handheld heating head and
fast heating rate.
Among all types of induction heaters, mid frequency induction heaters are the
simplest in term of design with the low maintenance, and are the most popular,
affordable and reliable machines, especially between 15kw and 25kw models. The
large capacity and small size at an affordable price make these models the
standard equipment for a lot of factories, labs and workshops.
Main Features
·
Ease of use: just connect the power and the
water cooling system. Our simple instruction allows you to use the heater in 15
minutes.
·
3-5 meters extended handheld heating head
with power switch.
·
Precise control with digital time and current
displays.
·
Remote foot switch for safer operation.
·
Dual automatic and manual modes.
·
Optional graphite, MgO and SiO2 crucibles available. (melting material decides crucible type,
weight and size of the material decide crucible size)
·
Custom coil design available (fixed coil or coil on a cable
so it can be used by hand like a wand)
Indicators
·
Power
indicator:
When input power
is connected, circuit breaker in back panel and main power switch in the front
are turned on, this red light is on indicate the control power is OK.
·
Operation
indicator
This green light
will flash with intermittent buzzing sound (around one in each second) during
heating process.
·
Output
over voltage indicator
NULL
·
Water
fail indicator
The induction coil and some parts inside
the machine are all cooled by cooling water. This machine comes with a built-in
water pressure sensor. If cooling water pressure is lower than the rated value,
this light will turn on with continuous buzzing sound, and the machine will
stop working automatically.
·
Phase
protection indicator
Control power is
drawn from two of the phases of a three-phase power. Two situations: A) One of
the control power phases is missing. Machine will not work and power indicator
is off. B) The phase other than the control power phases is missing, phase
protection indicator will light up, machine shuts down automatically with
buzzing sound.
·
Over
current indicator
When this light
turns on with continuous buzzing sound, machine will stop working
automatically. The followings are the possible causes.
b.
Interference
signal
c.
Equipment
failure
d.
Induction
coil short circuit caused by induction coil touching the work piece
e.
Contact
between induction copper turns
f.
Oven
temperature for some parts inside the unit
g.
Input
power overload capability
Restart the
machine normally should fix the problem. If this light comes up with sound
every time you start the machine, there might be a bad part which needed to be
replaced.
·
Short
circuit indicator
When this light is on and the alarm is issued,
the IGBT module or the auxiliary adjustment part of the voltage regulation part
may be damaged, or the short circuit sensor may be damaged. Please refer to the
fault guide or consult our company for repair.
·
Input
over voltage indicator
Input of 380-415VAC three
phase is required for this machine. When input voltage is higher than 430v,
this light will turn on with continuous buzzing sound, and the machine will
stop working automatically.
·
Over
temperature indicator
There is a heat sensor attached to the heat
radiator inside the machine, when the sensor detects a temperature higher than
55°C, over temperature light will come on with continuous buzzing sound.
Increase cooling water flow rate or lower water temperature could resolve this
issue.
·
Over
temperature indicator
When the
temperature of these devices is higher than 55 °C, the device will stop working,
the overheat indicator turns on with continuous buzzing sound. Increase the
water flow to reduce the temperature of the cooling water to release it.
·
Unit
frequency indicator
This light is on
when the device oscillates at a frequency lower than 30KHZ or higher than
100KHZ. The device will continue to operate, but the output voltage, power,
etc. will automatically attenuate to protect the device from damage. It can be
adjusted by the following methods: (1) If the frequency is too low, the number
of turns of the induction coil can be reduced, or the diameter of the induction
coil can be reduced, (2) If the frequency is too high, the number of turns of
the induction coil can be increased, or the inductance can be increased. The
diameter of the circle to reduce the frequency.
·
Frequency
(KHZ) indicator
This light will come up when the digital gauge
shows the oscillation operating frequency.
·
Current
(A) indicator
This light will come up when the digital gauge
shows output oscillator current.
·
Voltage
(V) indicator
This light will come up
when the digital gauge shows output oscillator voltage.
·
Power
(KW) indicator
This light will come up
when the digital gauge shows output oscillator power.
