English
External input device WCB 2 (optional)
The following functions are available when using an external
input device:
● Offset:
The actual temperature of the soldering tip can be changed
by + - 40°C by entering a temperature offset
● Setback:
Reduction of the setpoint temperature to 150°C /300°F
(standby). The setback period, after which the soldering sta-
tion switches to the standby mode, can be adjusted from 0 –
99 minutes. The setback state is indicated by a blinking
display of the actual value. After three setbacks, the AUTO
OFF function will be activated and the soldering tool will
switch off (blinking dash on the display). The setback state or
AUTO OFF ends after pressing a key or the finger switch.
At this time the setpoint will be displayed briefly.
● Lock:
Locking of the setpoint temperature and temperature win-
dow. No changes can be made to the soldering station set-
tings after locking.
● °C / °F:
Switching the temperature display from °C to °F and vice
versa. Pressing the "Down" key when switching the unit on
will show the current temperature version.
● 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" function 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:
Factory setting FSE (reset of all adjusted values to 0, tempe-
rature setpoint value: 350°C/660°F
● PC interface:
RS232 (WCB 2 only)
● Temp.gauge:
Integrated temperature gauge for thermocouple Type K
(WCB 2 only)

Maintenance and care
If the feed rate is irregular, the drive wheel can be cleaned
with a brass brush. First remove the control unit from the
feed unit. Push back the cover of the feed unit to access the
feed unit. Lift the drive wheel and clean.
Instructions for care of the
WSF P5/P8 / WP / WSP
soldering gun (heating
element, tip receptacle and
soldering tip)
Please clean the heating
element depending on how
much you use the soldering
gun.
Cleaning the heating element:
Remove any dirt and old solder from the tip of the gun.
Remove the tip receptacle by undoing the knurled nut/tip
receptacle. Take care not to crush the tip receptacles during
removal (in order to avoid damaging the heating elements).
Use wire brush T0051382799 for cleaning
Cleaning set WDC 2 T0051512699
Cleaning set WDC T0051512799.
Care of the soldering tip:
After lead-free soldering we recommend that you always
rewet the soldering tip with tin solder before putting the
soldering gun back into the stand. Always use our steel wool
for WDC 2 T0051512599 and WDC T0051512499 to clean
the soldering tip. We recommend using Tip Activator
(T0051303199) for non-wettable soldering tips.
4. Start-up
Establish the electrical connection between the feed unit and
the control unit. Insert plug (12) into socket (6).
Connect the soldering iron connections to the control unit
and feed unit. Insert the electrical connecting plug for the
soldering iron into the 7-pin socket (9) of the control unit, and
lock into place. Fully insert the wire lead into the connection
element (13) of the feed unit and fasten with the clamping
screw (17).
