Cooper Hand Tools PEWA Weller WS 51, Operating Instructions Manual

12

Thank you for placing your trust in our company by pur-
chasing 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 atta-
ched safety information carefully prior to initial opera-
tion. 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
sector. The analog electronic control system guarantees
the best possible control performance for various solde-
ring tools. The high-powered 24 V heating elements
make excellent dynamic performance possible, so that
the soldering tools can be used universally.

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 desired temperature can be set by a rotary potentio-
meter 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 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 overhea-
ting. (WS 81 only)

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.

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 solde
ring process. The 80-watt power and slim 
design makes this soldering iron suitable 
for fine soldering work. (cannot be used 
with WS 51)

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 (cannot be used 
with WS 51).

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 
(cannot be used with WS 51).

See "Accessories" for additional tools.
