Thank you for placing your trust in our company by purcha-
sing the Weller soldering stations WS 51 and WS 81.
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 51 and WS 81 corresponds to the
EC Declaration of Conformity in accordance with the basic
safety requirements of Directives 2004/108/EC, 2006/95/EC
and 2011/65/EU (RoHS).

2. Description

2.1 Control unit

The soldering stations WS 51 and WS 81 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 excellent dyna-
mic 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

WP 80:

The soldering iron WP 80 / WSP 80 is

WSP 80

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.

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.

See "Accessories" for additional tools.
