7 pole socket (9) on the front panel and lock. Position the
main filter (6) with the hose joint between the vacuum con-
nection (8) and the vacuum connection on the desoldering
tool. Check that the mains voltage matches that on the rating
plate and that the mains switch (1) is in the off position. Plug
the control unit into the mains (10). Switch on the unit at the
mains switch (1). When the unit is switched on, a self-test is
performed during which all the indicators (2) are illuminated.
The temperature set (required value) and the temperature
scale (ºC / ºF) are then briefly displayed. The electronics then
switch automatically to the display of the actual value. The
red dot (5) on the display (2) illuminates. This dot serves as
an optical regulation monitor. Continuous illumination means
that the system is heating up. Flashing indicates that the
operating temperature has been reached. The vacuum
necessary for desoldering is activated by the integrated fin-
ger switch on the soldering iron.
Setting the Temperature
Ordinarily the digital display (2) indicates the actual tempe-
rature. When the "UP" or "DOWN" button (3) (4) is operated
the digital display (2) switches to the display of the required
value currently set. The required value set (flashing display)
can be changed in the corresponding direction by repeated-
ly pressing or holding down the "UP" or "DOWN" button (3)
(4). The required value can be changed more quickly by hol-
ding the button down. Approx. 2 sec. after releasing the but-
ton the digital display (2) switches automatically back to the
actual value. It is not possible to make changes to the set-
ting on a locked soldering station (LOCK).
Standard setback
If the soldering tool is not used within a period of 20 minu-
tes 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.

via 3.5 mm jack bushing on the bottom of the unit. (State upon delivery: hard grounded,
plug is not inserted)
Activating the standard setback function: When switching on
the unit press the "UP" button (3) until "ON" appears in the
display. The setting is saved when the "UP" button is relea-
sed. 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 setback function.
Vacuum delay
After the finger switch is released the vacuum remains acti-
ve for approx. 2 seconds.
Setting: When switching on, hold the "DOWN" key (4) until
ON or OFF appears in the display. The setting is saved when
the "DOWN" button is released. Repeat this step to change.
Maintenance
To obtain good soldering results it is important to regularly
clean the desoldering head. This includes emptying the tin
collection container, replacing the glass tube filter, as well
as checking the seals. Correct sealing of the front face of the
glass cylinder ensures full suction performance. Dirty filters
affect the flow of air through the soldering tool. The main fil-
ter (6) (hose-mounted filter in the vacuum hose) should the-
refore be checked regularly and replaced if necessary. Use a
new original WELLER filter cartridge for this purpose. To
clean the bore in the suction nozzle and the suction tube, use
the cleaning tool (5 13 500 99).
The suction nozzles can be replaced quickly and easily with
a short turning movement (approx. 45°).
Large deposits in the area of the cone will prevent the inser-
tion of a new suction nozzle. Deposits can be removed with
the cleaning insert for the heating element cone.
Warning: Working without a filter will irreparably dama-
ge the compressed air converter.
