Caution!
The soldering tip heats up to 450°C.
Before using the soldering iron, check that the
■
spring securing the soldering tip is correctly
hooked.
Ensure that the soldering tip does not come in
■
contact with skin or heat-sensitive materials.
Remove flammable objects, fluids and gases from
■
the working area of the soldering iron.
Always put the soldering iron in the holder when
■
not in use.
Information on soldering
The soldering joints must always be clean and free
■
of grease.
We recommend to keep the soldering times as
■
short as possible. However, the soldering joint must
be heated sufficiently and evenly to achieve good
soldering results.
Prior to soldering lightly wipe the tip with a damp
■
sponge so that it regains its metallic shine. By
doing so, oxidized solder or remains of burnt flux
agents are prevented to come in contact with the
soldering joint.
Heat the soldering joint up by bringing the tip
■
simultaneously into contact with the land (pad) and
with the component connection.
Apply solder wire.
■
Repeat this soldering process.
■
Wipe the soldering tip with a moist sponge from
■
time to time. Soiled soldering tips prolong the time
needed for soldering.
Do not wipe the soldering tip after finishing the last
■
soldering process. The remaining solder protects
the tip from oxidation.
Processing sensitive components
[fig. II]
Some components can be damaged by electrostatic
discharging (pay attention to the warnings on the
packaging or ask the manufacturer or supplier). Use an
ESD-save workplace to protect these components (ESD
= electrostatic discharge).
A soldering station can be integrated easily into such
an environment. Install a high impedance connection
(220 kΩ) between the soldering tip and the conductive
work base using the potential equalization jack [4].
Changing the soldering tips [fig. III]
The soldering tip must be changed if the solder-
ing tip is worn or if another shape is required. The
soldering tip can be replaced even if it is hot. How-
ever, the power supply unit should be switched off.
Otherwise the heating element can overheat without
the soldering tip.
Procedure
Lift the spring hook off the boring
■
remove the tip with flat-nose pliers.
Place the hot soldering tip on a fire-proof sup-
■
port or into the holder.
Attach the new tip. When sliding the tip to the
■
stop, ensure that the slit of the tip shaft slides
directly over the nose of the heating element's
metal tube. By doing so the soldering tip is
positioned and secured against twisting.
Fix the tip by hooking the spring hook to the
■
boring using flat-nose pliers.
Note
To achieve good electrical and thermal
conductivity, we recommend to remove
the soldering tip from time to time and
to brush the heating element with a
small brass brush.
Calibration
In general, it is not necessary to calibrate the solder-
ing station.
If, however, a special soldering tip is used or if the
soldering temperature must be set with high preci-
sion in a certain range, the actual tip temperature
can be harmonised with the scale by doing the
following:
Equip the soldering iron with the required tip
■
and set the required working temperature.
Use a measuring device to determine the
■
temperature of the soldering tip. If the measured
temperature is stable, compare this value with
the set temperature.
If the measured temperature is too low, turn the
■
calibration potentiometer clockwise, if it is too
high counter-clockwise.
Make sure that the soldering tip is clean and the
air conditions are steady. Open windows, walk-
ing persons and similar factors can falsify the
measurements.
