1. Description

1.1 Control unit

The microprocessor-controlled soldering station WSD 81 is part of a family of units that has
been developed for industrial production technology and for the service and laboratory sec-
tor. The digital control electronics and a high-quality sensor and heat exchange system in the
soldering tool guarantee precise temperature control at the soldering tip. The highest degree
of temperature precision and optimal dynamic 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 WSD 81 and the corre
sponding control parameters are assigned accordingly.
Various equipotential bonding possibilities for the soldering iron tip, zero power switch and
antistatic design of control unit and iron complete the high quality standard. The possibility
of connecting an external input unit further increases the variety of functions of this soldering
station. With the optional input units WCB 1 and WCB 2 it is possible to implement time
functions, locking functions, etc. Integrated temperature gauge and PC interface are included
in the extended scope of the input unit WCB 2.
The temperature is set in a range between 50 °C and 450 °C using two buttons (up/down).
The setpoint and actual value are displayed digitally. A blinking red LED in the display signals
that the preset temperature has been reached – this serves as a optical regulator. Constant
illumination means that the system is overheating.
1.2 Soldering irons
LR 21: Our "standard" soldering iron. With a power of 50 watts and a wide spectrum
of soldering tips (ET series) this soldering iron can be used anywhere in the
electronics sector.
MLR 21: With its 25-watt power and slim design, this micro-soldering iron is especially
well-suited for fine soldering work with a low heating requirement.
MPR 30: The Weller Peritronic MPR 30 soldering iron has an adjustable working angle
of 40° to enable an individually ergonomic soldering process. The 25-watt
power and slim design makes this soldering iron suitable for fine soldering
work.
WTA 50: The unsoldering tweezers WTA 50 were specially designed for unsoldering
SMD components. Two heating elements (2 x 25 watts), each with its own
temperature sensor, ensure constant temperatures at both ends.
LR 82: High-performance 80 watt 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.
GB
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 watts makes universal usage possible - from extremely fine to high-
temperature soldering work. Work can be continued immediately after switching
soldering tips, since the temperature is reached again quickly.

2. Starting

Assemble soldering iron rest (see exploded drawing).Place the soldering iron in the safety
rest. Insert the soldering iron plug into the connection bush (7) of the control unit and lock by
turning to the right. Check that the power supply corresponds to the specifications on the
name plate and that the power switch (1) is in the OFF position. On version that can be
switched, set the voltage on the selection switch (set in the 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
