factory to 240 V). 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 set temperature and displays this value. Constant illumination
means that the system is overheating. 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
If the soldering tool is not used within a period of 20 minutes the temperature will be
automatically reduced to a standby temperature of 150 °C (300 °F). After three
setback periods (60 min.) the "AUTO OFF" function will be activated and the
soldering iron will be switched off.
Activating the standard setback function: When switching on the unit press the "UP"
button until "ON" appears in the display. Use the same process to switch the unit off.
"OFF" will appear in the display (state upon delivery).
The use of very fine soldering tips may have a negative effect on reliable function.
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.

3. Equipotential bonding (not USA )
The various circuit elements of the 3.5 mm jack bush make 4 variations possible:
Hard-grounded: No plug (delivery form)

Equipotential bonding:

With plug, equalizer at center contact
(impedance 0 ohms)
Potential free: With plug
Soft-grounded: With plug and soldered resistance. Grounding via set
resistance value.

4. 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 fluxing 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 1 and WCB 2 (optional)
The following functions are possible when using an external input unit.
b Offset:
The real temperature of the soldering iron can be changed by ± 40 °C
by input of a temperature offset.
b Setback:
Reduction of the setpoint temperature to 150 °C (standby). The
setback time can be set at 0-99 minutes after the soldering 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).
