OPERATION
Turning on
Turn on using the switch on the rear of the
control unit. The version of the software will first
be displayed, and then the OFF screen will
appear.
Description of controls
- PEDAL:
Hot air is produced when it is held down.
Releasing it returns the system to OFF, though
the turbine continues to operate until the air
temperature falls below 100°C.
- KEYS:
Performs the same function as the pedal.
VACUUM
On/off switch for the suction pump.
- CONTROLS:
TEMPERATURE
SELECTION
This enables temperatures from 150 to 450°C
to be selected.
The display shows the actual air temperature
when the unit is working.
AIR FLOW
REGULATION
This enables the air flow to be set on a scale
from 1 (corresponding to the lowest setting
of 6 l/min) to 10 (corresponding to the highest
of 34 l/min).

DESOLDERING PROCEDURE
Depending on their size, the protectors and
extractors are grouped on the console in three
colours - yellow, orange and red - like the
temperature and air-flow regulating scales on the
front panel of the station. This means that, according
to the extractor size, we would recommend air-flow
and temperature selection to match colour codes.
We would also recommend the use of the nozzles
of larger diameter, reserving the smallest one
(diam. 4 mm) for desoldering small components
such as resistors, condensers and the like, bearing
in mind that with this small nozzle the concentration
of heat is greater and care must be taken to avoid
burning the printed circuit; we recommend keeping
below a temperature of 350 °C and air flow of 6.
Depending on the size of the integrated circuit to
be desoldered, you will have to use:
A ) Protector + trípod
B ) Extractor
C ) Tripod
A) Protector + tripod:
- Select protector and tripod size in function of
the IC to be desoldered and place it over the
component.
- Use the VACUUM button to start the suction
pump and then fit the tripod. Press the sucker
down until it sticks onto the component.
