requirement. Easy to use shape combi

Fast warm-up time and precise tempera
ture regulation characterise the soldering
irons in this power range.
See "Accessories" for additional tools.

3. Starting

Assemble soldering iron rest (see exploded drawing).Place
the soldering iron in the safety rest. Insert the soldering iron
plug into the connection bush (6) of the control unit and lock
by turning to the right. Check that the power supply corre-
sponds to the specifications on the name plate and that the
power switch (1) is in the OFF position. On version that can
be switched, set the voltage on the selection switch (set in
the factory to 240 V). On version that can be switched, set
the voltage on switch (10) and insert the appropriate fuse (9).
Connect the control unit to the power supply. Switch on the
unit at the power switch (1). When switching on the unit, a
self-test is carried out in which all display elements (2) are
switched on briefly. The electronic system then switches
automatically to the actual temperature and displays this
value. LED (5) illuminates. These light emitting diodes are
optical regulator monitors. Constant illumination means that
the system is heating up. The blinking light signals that the
operating temperature has been reached.
Setting the temperature
The digital display (2) shows the actual value temperature.
By pressing the UP or DOWN key (3, 4) the digital display (2)
switches to the setpoint. The setpoint can be changed by
tapping or by firmly pressing the UP or DOWN button (3, 4)
in the desired direction. Pressing the button will change the
setpoint quickly. The digital display (2) returns automatically
to the actual value approximately 2 seconds after releasing
the button.
Standard setback:
Setting back the set temperature to 150°C. The setback
time, which follows the switching of the soldering station to
standby mode, is 20 minutes. After three setback times (60
minutes) the "Auto-off" function is activated. The soldering
tool is switched off (blinking line on the display).
Setting: When switching on, hold the "UP" key (3) until ON or
OFF appears in the display. Repeat this step to change.
Maintenance
The transition between the heating element / sensor and the
tip of the soldering iron may not come in contact with dirt,
foreign particles or become damaged, since this affects the
precision of the temperature control.

4. Equipotential bonding

The various circuit elements of the 3.5 mm jack bush (6)
make 4 variations possible:
Hard-grounded:
No plug (delivery form)
Equipotential bonding (impedance 0 ohms):
With plug, equalizer at center contact
Potential free:
With plug
Soft-grounded:
With plug and soldered resistance.Grounding via set resi-
stance value.
5. Instructions for use
For initial heating, coat the selective tinnable tip with solder.
This removes any oxidation or dirt on the tip which may have
occurred during storage. During pauses between soldering
and before storing the soldering iron, ensure that the tip of
the soldering iron is well coated. Do not use aggressive flu-
xing agents.
Note: Always ensure the proper position of the soldering
iron tip.
These soldering irons have been adjusted for an average-
size tip. Deviations can occur due to exchanging of the tip or
using other tip designs.
External input unit WCB 2 (optional)
The following functions are possible when using an external
input unit.
Offset:
The real temperature of the soldering iron can be changed
by ± 40°C by input of a temperature offset.
Setback:
Reduction of the setpoint temperature to 150°C (standby).
The setback time can be set at 0-99 minutes after the sol-
dering station has switched to standby mode. After a period
equal to three times the set-back time, the "Auto Off"
function is activated. The soldering iron is switched off
(flashing dash on the display).
Lock:
Locking the setpoint temperature. Settings cannot be chan-
ged after the soldering station has been locked.
