Thank you for placing your trust in our company by purcha-
sing the Weller soldering stations WS 81 and WS 51.
Production was based on stringent quality requirements
which guarantee 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 soldering stations WS 81 and WS 51 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 soldering stations WS 81 and WS 51 are a part of the
range of products which were developed for industrial
manufacturing as well as for the repair and laboratory sec-
tor. The analog electronic control system guarantees the
best possible control performance for various soldering
tools. The high-powered 24 V heating elements make excel-
lent dynamic performance possible, so that the soldering
tools can be used universally. 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 desired temperature can be set by a rotary potentiome-
ter in an infinitely variable range between 150°C - 450°C.
The set temperature can be locked by the key switch (4)
integrated in the front plate. Temperature settings cannot be
changed when the unit is locked. A blinking green LED in the
display signals that the preset temperature has been rea-
ched.
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 solde-
ring 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 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.
