4. INTRODUCTION

4.1 SCOPE

This device generates an alternating current of high frequency. The current passes through a
focusing tip and 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 within the work field of the instrument. The
more easily magnetizable material, the more heat it creates. That is why the device heats
conductive metals and their alloys easily but has no effect on glass, plastics, wood, textiles and
other non-conductive materials.

8. ASSEMBLING THE INDUCTION HEATING TOOL

8.1 UNPACKING AND FIRST START

1. Unpack the device and any accessories supplied and check that they are in good order and
the device and the accessories are not damaged. If you find any defects, do not continue !

2. Leave the device to acclimatise for 15 minutes.

3. Important: Remove the sealing ring located under the coolant tank filling hole lid tab. Pull to
remove the lid tab and take out the sealing O-ring. Then push the tab, including the foam
gasket, back into the tank lid. Keep the O-ring for potential future use if sending the machine
via a parcel service.

4. If the focusing head is not attached, screw it on .

5. The machine is pre filled with coolant, approximately 2.5L.

6. A plug must be fitted, a 16Amp plug is recommended to get the best performance from the

machine. A 13Amp plug can be fitted but the machine MUST be reduced to 70% power. See

page 18 for Input Current Limit instructions.

7. The cooling circuit venting is activated automatically, and the letters “FIL” flash on the

electronic display during this. The coolant level decreases during the filling .

8. After completion of the venting, turn the device off and check the coolant so that the coolant
level shown on the gauge at the back of the device is about 1 cm above the bottom of the
tank.

9. Repeat the procedure if needed.

8.2 COOLANT REFILLING

Check and refill the liquid coolant before each device starting. Use the original Draper liquid
coolant only!

DO NOT USE WATER !

The device has integrated coolant level inspection. If the coolant runs low, the device
stops heating and displays the error message “E##”. In that case, refill the coolant in the tank
as described in chapter 6.1 point 6 - 9.

8. ASSEMBLING THE INDUCTION HEATING TOOL

8.3 SUPPORTED TECHNOLOGIES

1) HCS3 - Heating Control System 3

This technology enables controlled heating with multiple function real time control of machine
parameters, which is the heart of the device features. The induction heating system can be
controlled in various modes, increasing its applicability and versatility. The ability to pre-set the
parameters enables use on low amperage power supplies, where it will not trip circuit breakers
etc.

2) BIPT – Boost Induction Power Technology

Enables increasing output power for better and faster material heating. This technology operates
primarily in open coils, heating various types of material.

3) DIPA - Dynamic Induction Power Adjust

Automatic optimum setting of required power for achieving max. efficiency, speed and long-term
heating in dependence on other heating parameters.

4) QST - Quiet Cooling Technology

An adaptive mode optimising cooling for quiet operation or maximum power output.

5) URC - Universal Remote Control

Allows universal remote device control, both analog and digital, or using a data bus, enabling easy
integration into production process machinery.

6) ACMS - Automatic Check And Monitor System

Combines features that check and verify device functionality and condition after activation, and a
feature that constantly supervises and monitors the heating and operational parameters for
maximum device safety and reliability.

7) DFU - Device Firmware Update

Enables updates to the firmware.
Heating modes and their application

The heater has available three different heating modes:

8) Controlled Field or Burner Power Mode (CF)

In this mode, the induction heater maintains the same intensity of the magnetic field regardless of
the conditions surrounding the induction tip. The heater behaves similarly to a gas burner, where
the set field intensity matches the flame power. The amount of introduced heat is then easily
controlled by moving the burner nearer or further from the material, similarly to flame heating.

The advantage is that it is easier to control the introduced heat as needed and, most importantly, it
allows finer and sensitive heating, e.g., in car repairs (warming window edges when removing
windows, bodywork plates for easier removal of stickers, rubber parts, etc.).

Another advantage is that moving the burner away does not increase the power output and
resulting needless device overheating, and increases the maximum continuous heating time and
saves energy.

Advantages:

• Power control by moving nearer or further .

• Fine heating.

• Lower loss in heating, particularly for open coils or when moving focus coil away from

material .

9) Controlled power mode (CP)

In this mode, the device tries to deliver and maintain the set amount of introduced heat or energy
to the material. The advantage is a controlled amount of heat introduced to the material, which
combined with timing enables relatively accurate heating to a set temperature, e.g., for repeated
pre-heating in production, etc.

- 12 -

8. ASSEMBLING THE INDUCTION HEATING TOOL

The disadvantage of this mode is that when moved further from the material, the device
significantly increases the power output to maintain the heat delivery level to the material, thus
increasing the loss and resulting in a faster device overheating. The efficiency is reduced as well.

Advantages:

• The device automatically maintains the set amount of heat introduced to the material, thus

heating the material accurately.

Drawback:

• The disadvantage is the great increase in the induction output when moved away from the

material or with inappropriately chosen coil, resulting in high heating load and quick
temperature increase, reducing in turn the load factor and rapidly overheating the device.

• The efficiency is reduced.

10) Controlled heating

Using the heating timer

The device has an integrated heating timer for easy setting of desired heating time, which
combined with the controlled power mode enables relatively accurate and repeatable heating with
controlled heat introduction, i.e., heating to a set temperature.

8.4 REMOTE CONTROL AND INTEGRATION INTO PRODUCTION

PROCESS

The device has a universal remote control system that enables its easy integration into automated
production processes or facilitated work in small batch production. The device can be controlled
using a foot pedal, switch contact, analog signal both based on voltage and current coil, and
provides logical outputs informing about the system status. In the highest class, it supports full
control via a digital data bus, enabling both full control and complete system monitoring.

coolant in the tank.

• If everything is in order, the device switches to standby.

9.3 STANDBY

This is the initial device status, which allows turning the selection wheel to set the desired heating
power or temperature, depending on the mode selected:

• Controlled power mode (CP), indicator lamp glows red – the user sets the desired heating

power in % of maximum heating power and the device automatically adjusts the required

parameters to maintain the set power.

• Controlled magnetic field mode (CF), indicator lamp glows green – the user sets the desired
field intensity in % of maximum field intensity and the device automatically maintains the set

field intensity.

The indicator lamp starts flashing during the heating and the display shows the current readings of
power output in kW.

Limitation OL --- = no limitation

po = max. power transmitted
ic = max. input current
oc = max. output current
dut = max. inverter duty
tE = temperature

Errors Err error history

Note: See annex for a list of errors.

1) P – Power transmitted

Shows the current device power output in Watt, which approximately (after deducting loss in cable
and heating head) matches the power or energy introduced to the material being heated. It is thus
a parameter directly related to heating speed and temperature. This transmitted power increases
with growing bond (decreasing gap) between the heating coil and the material.

2) Po – Output power

Related to inverter output power and shown in VA (volt-amperes). It is the so-called apparent
power. It is directly related to the power or intensity of the magnetic field that the heating coil
produces. When the bond between the induction coil and material decreases, or when heating
less magnetic or non-ferrous metal materials, this output power has to increase in order to
maintain the same amount of energy or heat introduced to the material, increasing the loss in turn.
Increasing output power can achieve higher transmitted power, enabling heating of non-ferrous
metals, for example.

3) PF – Power Factor

This indicates the relative quality of the heating induction circuit and is directly related to the bond
between the induction coil and the material, making this parameter very useful for selecting the

optimal coil. The closer the number to 100%, the higher the efficiency of heating energy
transmission to the material, and vice versa. Generally speaking, if PF=100%, all the energy goes
straight into the material and the heating has maximum efficiency. With lower PF, only a part of the

energy is transmitted into the material and part oscillates in the coil.

The PF is the highest with a focus adapter, applied tightly to a thick material. Moving away from
the material quickly reduces the PF. For open coils, the more accurately the coil sits on the
material and the smaller the gap between the coil and the material, the higher the PF and the

more efficient the heating. The recommended gap is approx. 2-5 mm. With smaller gaps, heat
from the material being heated is transmitted into the coil, resulting in a faster device overheating.

- 16 -

9. INDUCTION HEATING TOOL INSTRUCTION

4) Frequency “FrE”

The current heating frequency, which should be within 25-40 kHz with a correctly selected coil,
depending on the load and the material being heated. If it deviates significantly, the device
displays a warning, meaning that the user should use a more appropriate coil. If the frequency
exceeds the limit values, the device turns itself off and reports an error.

5) Output current

Indicates the current delivered by the inverter to the resonance circuit in Amperes.

6) Input current

Indicates the current consumption from the power line in Amperes.

7) Input voltage

This is the current power line voltage in Volts.
It is possible to limit the input amperage if a 16Amp supply is not available.
This is also useful for use with generators, providing the generator is able to provide a stable and

accurate 230V/13Amp/50Hz output, - and an output rating of at least 6kVA

8) Cooling temperature

Indicates the average temperature of the cooling liquid and device components in degrees
Celsius.

9) Limitation

Indicates power or parameter limitation, if any, during the heating. For example, if the user sets the

desired power to 3.5 kW using an inappropriate coil, the device will not only display a low power

factor (PF), it will also indicate a duty-type limitation at the output, meaning that the inverter cannot

deliver any more energy. Alternatively, if the user sets a current limit at the input to, say 10A, the
device reports that the power is limited by the input current. If heating proceeds correctly and in
the optimum band, the device will always display “---”, meaning that the device is not limited by
anything.

10) The heating is limited:

• “---” = no limitation, heating proceeds optimally

• “po” = by maximum device power

• “ic” = by maximum input current

• “oc” = by maximum inverter output current

• “dut” = by maximum inverter output voltage

• “tE” = by max. temperature

1) The indicator lamp has to following statuses:

Indicator lamp Status

RED Parameter selection
GREEN Value setting

The following parameters can be set:

Description Display Value Unit

Return / exit --- ---

Heating mode REG CF = constant magnetic field / current

CP = constant heating power

Remote control rc OFF

PEd = on/off control, power set on device
PEA = analog, current coil (0-5V/10V)

Input Current Limit ic.L min 6.0A, max 16.5A = limitation on maximum input current
Max. output power Po.L min 2kVA, max 4.5kvA; default m is 4kVA
Cooling CoL Lo = silent mode (workshops, short-term capacity)

Std = standard mode
Hi = max. capacity / does not switch off

Water Fill FIL no

yes = activates filling and venting

Factory setting FAC no

YES = load factory setting
Unlock code UnL Servicing menu code

Firmware Fir Display firmware version

2) “HC“ Heating mode

Enables selection of desired heating mode – see chapter Heating modes. The following options
are available:

• CF = control based on desired magnetic field intensity

• CP = control to desired heating power

3) “Po L” Maximum output power

Allows you to select the maximum inverter output power, which is convenient for small coils,
limited by maximum power or current. This enables use of specialised, small or wire coils, which
would otherwise overheat.

The other advantage is the possibility of limiting the max. power to the minimum required,
which in combination with the CP power control mode significantly reduces device
overheating and increases the heating efficiency.

4) “ic.L” Power Line Current Limit

Enables limitation of current consumed from the power line, which permits trouble-free use of the
device in power grids with poorer switch gear or low amperage availability, e.g., in repairs,
construction industry, workshops, when using a generator etc.

5) “FIL” Coolant filling and venting

Used for manual activation of venting and coolant filling.

6) “CoL” Cooling settings

Used for selecting the preferred cooling mode. The following options are available:

• Lo – silent mode, where the user prefers quieter cooling and does not mind higher grip
temperature. It is convenient for small workshops and production floors that require silence.

• Std, standard – optimum choice between the silent mode and maximum power, suitable for
general use.

• Hi – maximum capacity mode, increasing the cooling intensity at the expense of noise. The
advantages are lower grip temperature and maximum power. It finds application in more
demanding uses.

7) “RC” Remote control

Remote device control settings. The following options are available:

• PEd - pedal = heating is activated by stepping on a pedal, with power set on the device.

• PEA – analog pedal = heating is activated and power adjusted by a pedal, or heating

activation and deactivation is controlled by analog signal 0-5V, or 0-10V or a current coil
20mA.

8) FAC “Factory setting”

Reverts to factory settings.

9) Firmware

9. INDUCTION HEATING TOOL INSTRUCTION

9.8 REPLACEABLE HEATING INDUCTOR EXTENDERS

The induction heater device comes with a basic focusing heating inductor. Other coils, extenders
and heads are available - see drapertools.com.

Correct and safe functioning of the device requires the use of only original heating inductors,
extenders, adaptors and other accessories in accordance with their respective instructions for use.

The lifetime of each type of heating inductor and accessory is shown in its instructions for use
along with inspection and maintenance frequencies.

9.9 HEATING INDUCTOR HEAD REPLACEMENT PROCEDURE

Warning: The induction heater head is liquid cooled.

Failure to follow these instructions will lead to loss of coolant - which will prevent use of the

machine if not refilled.

DO NOT refill machine with tap water, anti-freeze or any other liquid.
Use ONLY approved Draper liquid coolant.

1. Turn off the device using the switch at the back of the device.

2. Make sure the coolant tank is safely closed.

3. Grasp the grip so that it is in a vertical position with the head facing upwards, at least 20 cm
above the power supply unit. Maintain this position through the entire replacement procedure.

4. Unscrew the heating inductor head by rotating it counterclockwise until it is released.

5. Make sure the threads and contact surfaces of both the grip and the extender are clean and
free of signs of corrosion.

6. Mount the new complete head by freely rotating it clockwise until the outer contact surface of
the extender makes permanent contact, be careful not to cross thread during replacement.

7. Turn on the device and, after an initial venting of the cooling circuit, check the coolant level
and add coolant if necessary, following the procedure described in Chapter 8.2.

8. Make a visual check of the tightness of the head connection and any other connections of the
new head. If there is a coolant leak, safe use of the device is no longer possible.

9 Check the conductivity of the connection by briefly activating the device without any heating

inductor load.

• If the device display shows the output power, everything is alright.

If it shows “A.Fr”, the contact between the contact surfaces is incorrect. In that case, safe

use of the device is no longer possible.

Check fitment of head and re-attach correctly before use.

10. MAINTENANCE & TROUBLESHOOTING

When scheduling device maintenance you have to consider the degree and circumstances of
device use.

Considerate use and preventive maintenance help prevent needless defects and malfunctions.
Perform checks as per standards and law in force. Only workers with adequate electrical
engineering qualifications may carry out any jobs on the device.

WARNING!!

Any handling of the power supply, including maintenance, requires its disconnection from the
power supply. To prevent injuries, always disconnect the power cable and wait at least 2 minutes
before removing the casing. Discharge the capacitor circuits before any further work.

Periodic maintenance includes cleaning the device every half a year:

1. Disconnect the device plug from the socket and wait about 2 minutes (the capacitors inside
the device will discharge). Then remove the upper device casing.

2. Clean all dirty power electric connections and tighten any loose ones.

3. Clean the internal device parts (coolers in particular) to remove dust and dirt – for example
using clean compressed air, a soft brush and vacuum cleaner.

4. The upper casing has to be earthed – remember to connect the yellow-and-green earthing
wire before screwing it on.

5. After maintenance, carry out safety measurements as per standards in force.

Note: Never use solvents or thinners (e.g., acetone), because they may damage insulation,

plastic parts and lettering on the front panel!!

10.1 STORAGE

The device has to be stored in a clean and dry room. Protect the device from rain, direct sunshine
and frost.

After heating completion, leave the device switched on for 10 more minutes - it will be cooled down
by fans until it is cold, then it deactivates the fans. After that, turn it off using the master switch and
disconnect it from the power supply.

If you disconnect the device immediately, leave it and all the working coils to cool down for at least
15 minutes.
