safety requirements of Directives 89/336/EEC and
2006/95/EC.

2. Description

2.1 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 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 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 spon-
ding control parameters are assigned accordingly.
Various equipotenzial bonding possibilities for the soldering
iron tip, zero power switch and antistatic design of control
unit and iron complete the high quality standard. The possi-
bility 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 imple-
ment time functions, locking functions, etc. Integrated tem-
perature 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 setpo-
int 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 heating up.
2.2 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.
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 sol-
dering work.
WTA 50: The unsoldering tweezers WTA 50 were speci-
ally designed for unsoldering SMD compo-
nents. 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 tempe-
rature quickly and precisely. Its slim design
and heating power of 80 watts makes univer-
sal usage possible - from extremely fine to
high-temperature soldering work. Work can
be continued immediately after switching sol-
dering tips, since the temperature is reached
again quickly.
WMP: Due to its handy design, the Weller WMP
micro soldering iron is suitable for work on
professional SMD electronics. A short distan-
ce between the handle and the soldering tip
ensures ergonomic handling of the 65W sol-
dering iron when performing the finest of sol-
dering tasks.
