OPERATION
Description of controls
- PEDAL:
Hot air is produced when it is held down.
Releasing it the heater is disconnected,
though the turbine continues to operate
until the air temperature falls below 100°C.
- BUTTONS:
Activates or desactivates the hot-air flow. After
a function-time of two minutes the hot-air flow
switches automatically off.
The red light indicates, that the heating element
is functioning. A malfunction is indicated by
the pulsing of the red led.
VACUUM
On/off switch for the self-contained suction pump.
The yellow light of the switch indicates that
the self-contained vacuum pump is activated.
- CONTROLS:
TEMPERATURE
Allows fixing the temperature of the heater
between 150 and 455°C. The selected
temperatures are reference values which
may change depending on the distance
between the heating element and the nozzle.
Allows fixing the temperature of the soldering
and desoldering iron between 100 and 371°C.
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).
- VACUUM SELECTOR:
Two vacuum inlets avalaible, being active
the one that coincides with the arrow.
HEAT
DESOLDERING PROCEDURE WITH THE
HEATER
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 + 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.
