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 (5) 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 selection switch (8) (set in
the factory to 240 V ). Connect the control unit to the power
supply. Set the temperature at the rotary potentiometer (3).
Switch on unit at the supply switch (1). Green LED (2) will
illuminate. This LED functions as the optical regulator.
Constant illumination means that the system is overheating.
The blinking light signals that the operating temperature has
been reached.
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 (4)
make 4 variations possible:
Hard-grounded:
Equipotential bonding:
Potential free:
Soft-grounded:
Grounding with set

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.
