Caution; Description; Technical Data; Commissioning - Cooper Hand Tools Weller WHS 40D Mode D'emploi

English
Thank you for placing your trust in our company by purcha-
sing the Weller WHS 40D soldering station. 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 WHS 40D soldering station corresponds to the EC
Declaration of Conformity in accordance with the basic safe-
ty requirements of Directives 89/336/EEC and 73/23EEC.

2. Description

We have manufactured the WELLER WHS 40D micro-proces-
sor controlled soldering station especially for the ambitious
electronic hobbyist. It is the correct tool for carrying out pro-
fessional soldering jobs in the electronic world. The digital
electronic control is particularly useful when working on
thermally sensitive components. The soldering iron temper-
ature can be adjusted through the range 150°C – 450°C via
the 2 UP/DOWN buttons. Both the temperature setting and
the actual temperatures are digitally displayed as part of the
temperature control system. A light in the display provides a
visual check. The associated WH 40 soldering iron is sup-
plied with a safety extra-low voltage and has a power rating
of 40 W at 200°C.
The "long-life" soldering bit has been given a galvanised
protective coating. This protective coating considerably
extends the working life of the soldering bit. The soldering
iron holder and the cleaning sponge are integrated in the sta-
tion housing.

3. Commissioning

Fit the stowage spring and the funnel; this is done by push-
ing the stowage spring clamp into the specially provided
recess (1). Soak the cleaning sponge (2) in water. Place the
soldering iron in the safe stowage position. Plug the solder-
ing iron plug (10) into the connection socket (4) in the control

unit. Compare the mains voltage against the details given on
the nameplate. If the mains voltage is correct, plug the con-
troller into the mains. Remove any combustible objects from
the vicinity of the soldering iron. Use the mains switch (9) to
switch on the unit. A self-test of all of the display elements
(5) that are used is carried out when the unit is switched on.
The pre-set temperature (the setting) is displayed for a short
period afterwards. The electronics switch over to the actual
temperature display afterwards. A red light (6) in the display
(5) illuminates afterwards. This light shows that the heating
pulse is present and is used as a visual check.
Temperature adjustment
In principle, the digital display (5) always shows the actual
temperature. The display changes to the actual pre-set tem-
perature if the "UP" (8) or "DOWN" (7) buttons are pressed.
The pre-set temperature setting (flashing display) can now
be changed by tapping or permanently holding down the
"UP" (8) or "DOWN" (7) buttons in the corresponding direc-
tion. If the button is permanently held down, the pre-setting
will change quickly. The display changes back to the current
temperature automatically approximately 2 sec after the but-
ton is released.
4. Working tips
The flux has a cleaning effect with regard to the dissolution
of oxide coatings on many metals. Flux-cored solder is used
virtually exclusively during electronic soldering. Rosin should
be used as the flux, which is a relatively non-aggressive flux.
Always ensure that the soldering bit is well tinned before tak-
ing a break from soldering or stowing the soldering iron.
Each mechanical operation damages the galvanic protective
coating of the soldering bit and drastically reduces the work-
ing life of the soldering bit.
The soldering bit (12) and the clamping screw (11) should be
removed from the soldering iron at regular intervals in order
to prevent "seizing up".
