DIGITAL CALIBRATION
H. Utilizing the Desolder Gun Digital Temperature Calibration
By default, the system is properly calibrated but for some cases when
a little adjustment of the desoldering gun temperature is required the
following procedure can be done.
1. Turn on the desoldering gun function.
2. Set to appropriate temperature you want to calibrate. Place the tip of
the desoldering gun on an external temperature meter.
3. The readings on the external temperature sensor should be more or
less equal to the displayed temperature.
4. If there are large discrepancy in the temperature reading we can re-
calibrate the temperature setting. First write down the set
temperature of the soldering iron and the actual temperature reading
from the external temperature meter. For example:
set temperature =300
external temperature = 350
Calibration needed = -50
5. Turn off the Desoldering Gun Function. Simultaneously press and
hold for 5 seconds the Desoldering Gun Function button
Desoldering Gun Up button .
6. The Desoldering Gun Temperature Display
panel) . Will switch to "000" indicating it is now in the desoldering
gun digital calibration adjustment mode. The calibration range is
from"-50" to "050" . The leading "-" sign signifies a negative
calibration number while the leading "0" signifies a positive
calibration number.
7. Use the Desoldering Gun Temperature Adjustment buttons ("6" from
the control panel) to increase or decrease the calibration number. In
our example the set temperature is 300 but the actual temperature
is 350, There is need to decrease the temperature by 50 degrees.
Press the down button until we reach "-50 ".
8. Save the value by pressing and holding the Soldering Iron Function
button ("4" from the control panel).

7. Check the tip temperature with an external temperature sensor,
adjust temperature settings higher or lower for the right temperature.
Or recalibrate at the desired temperature level
8. Ensure that all the solder is melted before triggering the pump.
(Partially melted solder will still be sucked up however it would clog the
barrel).
9. Upon pressing the pump trigger, hold the trigger for 1 to 2
seconds longer, as larger lumps of solder may need a longer suction
time to clear the barrel and go into the filter.
10. Clean the filter and dampen the sponge frequently during and after
usage to allow better suction power.
11. To deactivate the desoldering gun function press and hold the
desoldering gun function button for 3 to 5 seconds ("4" from control
panel).
Notes:
Industry recommended tip temperature for soldering is 600 to 610F
●
(315 to 320C) for standard solders and 650 to 700F (340 to 370) for
unleaded solders
Because of the difference in the heating element and size of the
●
soldering iron tip and desoldering gun, the soldering iron will heat up
faster than the desoldering gun. This is normal and does not have
any impact on the system's performance.
There will be a slight drop in temperature display once the trigger of
●
the desoldering gun is used. This is due to rapid intake of air in
which temperature is significantly cooler than the desoldering gun
tip. When the system detects this, it will automatically adjust the
temperature to compensate for the temperature difference.
NOTICE: When using the desoldering gun and soldering iron
simultaneously, the smoke absorbing function of the soldering iron
will be deactivated. This is to give priority to the desoldering gun.
