Caution; Description; Control Unit; Technical Data - Weller WSD 121 Manual De Uso

Thank you for placing your trust in our company by
purchasing the Weller Soldering Station WSD 121. 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 Weller Soldering Station WSD 121 corresponds to the EC
Declaration of Conformity in accordance with the basic
safety requirements of Directives 2004/108/EC and
2006/95/EC.

2. Description

2.1 Control unit

The soldering station WSD 121 was specially developed for
soldering tasks with an extremely high heat requirement. The
120 W heater power combined with the optimal transfer of
heat to the soldering iron bit guarantees the high
performance capability of the WP 120 soldering iron. As an
alternative to the WP 120, all the soldering tools listed in the
list of accessories can be connected to the unit.
A microprocessor makes operation simple and comfortable.
The digital electronic control system guarantees the best
possible control performance for various soldering tools. The
soldering tools themselves are recognized automatically by
the soldering station and assigned the corresponding control
parameters. The high-powered 24 V heating elements make
excellent dynamic performance possible, so that the soldering
tools can be used universally.

Via a 3.5 mm jack bush (initial state-hard-grounded)
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 further
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 functions, etc. Integrated
temperature gauge and PC interface are included in the
extended scope of the input unit WCB 2.
The temperature for the WP 120 soldering iron can be set over
the range from 50°C - 450°C via 2 buttons (Up/Down). The
setpoint and actual value are displayed digitally. A blinking red
LED in the display signals that the preset temperaturehas
been reached – this serves as a optical regulator. Constant
illumination means that the system is heating up.
2.2 Soldering irons
WP 120: The WP 120 soldering iron is characterised
by fast and precise achievement of the
soldering tip temperature. A particularly
powerful 120 W heating element guarantees
excellent dynamic behaviour.
The combination of slim design and
distance from handle to soldering tip means
that universal application is possible, from
extremely fine soldering tasks to those
which require high temperatures.
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 beused anywhere in the electronics
sector.
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.
