I. Utilizing the Desoldering Gun Digital Temperature Calibration
1. Turn on the Desoldering gun function switch.
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
5. Turn off the Soldering Iron Function switch (“14” from the control
panel) .Ensure that the Desoldering Gun Function switch is in the
off position(“12” from the control panel) .
6. Press and hold the UP button of the Soldering Iron Temperature
Adjustment button (“4” from the control panel) .
7. The Desoldering Gun Temperature Display (“14” from the control
panel) . Will switch to four zeros “000” indicating it is now in the
desoldering gun temperature calibration mode. Release the UP
button of the Soldering Iron Temperature Adjustment button (“4”
from the control panel) .
8. Use the Desoldering Gun Temperature Adjustment buttons (“5”
from the control panel) to increase or decrease the calibration
values. In our example the set temperature is 300 but the actual
temperature is 350, There is a difference of -50 degrees. Press
the up button until we reach “050- ”.
9. Confirm the change by pressing and holding the “UP” button of
the Soldering Iron Temperature Adjustment button (“4” from the
control panel).

4. Adjust the air flow level using the AIR PRESSURE ADJUSTMENT
BUTTONS (“3” from the control panel).
5. Adjust the hot air gun air temperature using the HOT AIR GUN
TEMPERATURE ADJUSTMENT BUTTONS (“2” from the control panel).
The prefix of the display for Hot Air Gun Temperature will change
from “C” to “c” indicating that air temperature is being adjusted. It
will return to “C” indicating actual temperature is displayed.
Reworking task can be started 1 minute after the desired hot air
temperature and airflow level are reached, as also indicated
from display panel “18” .
6. When reworking is complete, return the Hot Air Gun to its holder
but DO NOT immediately turn off the main power switch.
7. Deactivate the Hot Air Gun Activation button first in order to
activate the auto-cooling process. The system will start to blow
air (at room temperature) at a fast rate to reduce heat from the
hot air gun and bring down the temperature to a reasonable safe
level of 90°C. During this time, the air flow display will also
change “cool” while temperature is gradually decreasing. Once
the temperature drops to approximately 90°C the system will halt
and display “OFF” on the panel. It is now safe to switch off the
main power switch.
9. Turn OFF the main power switch.
10. Unplug the device from the main power source.
OPERATING GUIDELINES
IMPORTANT: When adjusting the air temperature, it is strongly
advised to initially increase the airflow level in order to man-
age the system temperature. This is to protect the heating
element inside the handle from excessive heat and avoid the
possibility of subjecting adjacent components to thermal
shock.
