Thank you for placing your trust in our company by pur-
chasing the WELLER soldering stations WSD 81 / WSL.
Production was based on stringent quality requirements
which guarantee the perfect operation of the device.
1. Caution!
Please read these Operating Instructions and the atta-
ched 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 soldering stations WSD 81 / WSL corre-
sponds to the EC Declaration of Conformity in accordan-
ce with the basic safety requirements of Directives
89/336/EEC and 73/23EEC.
2. Description
2.1 Control unit
The microprocessor-controlled soldering station
WSD 81 / WSL 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 elec-
tronics and a high-quality sensor and heat exchange
system in the soldering tool guarantee precise tempera-
ture 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 recog-
nized automatically by the WSD 81 / WSL and the corre
sponding control parameters are assigned accordingly.
Various equipotential bonding possibilities for the solde-
ring 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 furt-
her 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 func-
tions, 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 (150°F and 850°F) 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
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 electro-
nics 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 sui-
table 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 sen-
sor, ensure constant temperatures at both
ends.
LR 82:
High-performance 80 watt soldering iron
for soldering work with high heat require-
ments. 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 solde-
ring work. Work can be continued immedi-
ately after switching soldering 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
distance between the handle and the sol-
dering tip ensures ergonomic handling of
the 65W soldering iron when performing
the finest of soldering tasks.
