sing the WELLER desoldering station WDD 81V. Production
was based on stringent quality requirements which guaran-
tee the perfect operation of the device.

1. Caution!

Please read these Operating Instructions and the attached
safety information carefully prior to initial operation. Failure
to observe the safety regulations results in a risk to life and
limb.
The manufacturer shall not be liable for damage resulting
from misuse of the machine or unauthorised alterations.
The WELLER desoldering station WDD 81V corresponds to
the EC Declaration of Conformity in accordance with the
basic safety requirements of Directives 89/336/EEC and
73/23EEC.

2. Description

2.1 Control Unit
The microprocessor-controlled desoldering station WDD 81V
is part of a family of units that has been developed for indu-
strial production technology and for the service and labora-
tory sector. The digital control electronics and a high-quality
sensor and heat exchange system in the soldering tool gua-
rantee precise temperature control at the soldering tip. The
highest degree of temperature precision and optimal dyna-
mic thermal behavior under load conditions is obtained by
the quick and accurate recording of measured values in a
closed control circuit. The soldering tools themselves are
recognized automatically by the WDD 81V and the corre-
sponding control parameters are assigned accordingly. The
vacuum required for desoldering is generated by an internal
maintenance-free compressed air converter and is activated
via an integrated finger switch on the desoldering tool.
Various methods of equipotentially bonding the soldering iron
bit, a zero voltage switch, and the anti-static design of the
control unit and soldering tools supplement the high stan-
dard of the unit. The possibility of connecting an external
input unit extends the functional diversity of this desoldering
station. Additional functions including timing and interlockin
can be realised using the WCB 1 and WCB 2 Input Units,
available as optional extras. The extended features of the
WCB 2 Input Unit include an integrated temperature measu-
rement unit and a PC interface.
The required temperature can be set via 2 buttons (Up /
Down) over the range from 50ºC - 450ºC (122ºF - 842ºF).
Required and actual values are displayed digitally. A flashing
red LED in the display indicates when the selected tempera-
ture is reached, this LED serves as an optical regulation
17
monitor. The continuous illumination of the LED indicates
that the system is warming up.
2.2 Soldering tools
DSX 80: 80 W Desoldering Tool. Conical attachment
system for the suction nozzle. A wide range
of suction nozzles enables solder to be remo-
ved from a wide variety of solder joints. The
tin collection container can be changed easi-
ly without the need for tools. CSF desoldering
plungers for the desoldering of surface
mounted components are available as acces
sories. Integrated finger switch for activating
the vacuum.
DXV 80: 80 W Desoldering Tool. Conical attachment
system for the suction nozzle. In-line version
(vertical work position). Tin collection contai
ner integrated into the handle can be chan
ged easily without the need for tools. Wide
range of CSF (SMD desoldering plungers) and
suction nozzles. The vacuum is activated by
means of a finger switch.
LR 21: Our "standard" soldering iron. With a power
of 50 W and a wide spectrum of soldering tips
(ET series) this soldering iron can be used
anywhere in the electronics sector.
WTA 50: The unsoldering tweezers WTA 50 were spe
cially designed for unsoldering SMD compo
nents. Two heating elements (2 x 25 W), each
with its own temperature sensor, ensure con
stant temperatures at both ends.
LR 82: High-performance 80 W soldering iron for
soldering work with high heat requirements.
The soldering tip is attached by a bayonet
catch to ensure correct position when using
different tips.
WSP 80: The soldering iron WSP 80 is characterized
by its capacity for reaching the soldering
temperature quickly and precisely. Its slim
design and heating power of 80 W makes
universal usage possible - from extremely
fine to high-temperature soldering work.
Work can be continued immediately after
switching soldering tips, since the tempera-
ture is reached again quickly.
See "Accessories" for additional tools.

3. Commissioning

Place the soldering tool in the holder. Insert compressed air
hose with 6 mm outer diameter in the quick action coupling
for the compressed air connection (12). Provide supply of
compressed air with 600 kPa (87 psi) dry, oil-free compres-
sed air. Plug the electrical lead from the soldering tool in the
