OPERATION
Turning on
Turn on using the switch on the rear of the
control unit. The screen shows OFF.
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 (212°F).
- BUTTONS:
Activates or desactivates the hot-air flow. After a
function-time of two minutes the hot-air flow
switches automatically off.
VACUUM
On/off switch for the self-contained suction pump.
- CONTROLS:
TEMPERATURE
This enables temperatures from 150 to 455°C
(300 to 850°F) to be selected.
The selected temperatures are reference
values which may change depending on the
distance between the heating element and
the nozzle.
The display shows the actual air temperature
when the unit is working measured at a
distance of 10mm from the nozzle.
AIR FLOW
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 45 l/min).

DESOLDERING PROCEDURE
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 (662 °F) and air flow of 6.
Depending on the size of the integrated circuit to be
desoldered, you will have to use:
A) Protector + tripod
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 pump and
then fit the tripod. Press the sucker down until it
sticks onto the component.
