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 auto
matically 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

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.
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 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).
Lock: Locking the setpoint temperature. Settings cannot be changed after the
soldering station has been locked.
°C/°F: Switching the temperature display from °C to °F, and vice versa.
Window: Limitation of the temperature range to max. ±99 °C based on a locked
temperature resulting from the "LOCK" function. The locked temperature
represents the median point of the adjustable temperature range.
For units with a floating contact (optocoupler output) the "WINDOW" func-
tion is used to adjust a temperature window. If the actual temperature is
within the temperature window the floating contact will be enabled
(optocoupler output).
Cal: Re-adjustment of the soldering station (WCB 2 only).
PC interface: RS232 (WCB 2 only).
Temp. gauge: Integrated temperature gauge for thermal element Type K (WCB 2 only).
