1. Description

1.1 Control unit

The microprocessor-controlled soldering station PUD 81R is part of a family of units
that has been developed for industrial production technology and for the service and
laboratory sector. 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 ther-
mal 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 PUD 81R 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 stan-
dard. 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 tempera-
ture 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 (150°F and 850°F) using
two buttons (up/down). The setpoint and actual value are displayed digitally. A blin-
king 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. If the temperature is outside the temperature window set, this is indica-
ted on the display at 2 sec. intervals with "HI" (HIGH: temperature too high) or "LO"
(LOW: temperature too low).
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 80: The Weller Peritronic MPR 80 soldering iron has an adjustable
working angle of 40° to enable an individually ergonomic soldering
process. The 80-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 unsolde-
GB
ring 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.
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.
WMP: Due to its handy design, the Weller WMP micro soldering iron is suita-
ble for work on professional SMD electronics. A short distance bet-
ween the handle and the soldering tip ensures ergonomic handling of
the 65W soldering iron when performing the finest of soldering tasks.

2. Commissioning
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 type plate and that the power switch (1) is in the OFF position.
