Caution; Description; Technical Data; Starting - Cooper Hand Tools Weller WMD 1S Mode D'emploi

Thank you for placing your trust in our company by purcha-
sing the WELLER solder / desolder unit WMD 1S.
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 solder / desolder unit WMD 1S corresponds
to the EC Declaration of Conformity in accordance with
the basic safety requirements of Directives 89/336/EEC
and 73/23EEC.

2. Description

The WMD 1S is a solder / desolder unit, which has an out-
standing range of functions. All the soldering attachments
listed in the accessories list (25 W-150 W) may be connec-
ted alternately. Adjustment of the different soldering devi-
ces is not necessary since the integrated microprocessor
automatically recognises the connected device and optimi-
ses the relevant parameters for optimum control. The tem-
perature is controlled digitally. The required process para-
meters for temperature and air are entered via three user-
friendly buttons (Up, Down, Air). Set value and actual value
are displayed digitally.
With the hot air pencil temperatures of 50°C – 550°C can
be realised, on the connection of a soldering iron or desol-
dering iron the adjustment range is automatically limited to
max. 450°C. The achievement of the pre-selected tempe-
rature is indicated by a flashing dot on the display.
Continuous illumination signifies that the system is war-
ming up. The air for the hot air pencil and the vacuum for
the desoldering iron are generated using an internal pump

and activated using a microswitch on the soldering tool.
Various timing functions for the soldering tools and a lock
function (keylock) for the process parameters can be set
using the WCB1 and WCB2 external data input units.
A wide range of products including hot-air jets, suction
nozzles and soldering bits are available which allow many
different soldering tasks to be undertaken.
The metal casing is anti-static coated. The soldering bit
can
be grounded via a 3,5 mm connector on the rear side of
the instrument. The hot-air stream is free from static char-
ge. The solder / desolder unit WMD 1S therefore complies
with all requirements of the EGB safety.

3. Starting

Place the soldering bit in the safety holder. Connect the
connecting cable on the control instrument.
- Plug in, and latch the electrical connector on the 7 ter
minal connector (1).
- For the hot-air pencil: Push the air hose onto the „AIR"
nipple (10).
- For desoldering: Push the vacuum hose onto the „VAC"
nipple (9).
Attention: To avoid injury, the vacuum hose of the des-
olderer should never be connected to the „AIR" nipple.
Check whether the mains voltage matches the information
on the rating plate. In the case of correct mains voltage,
connect the controller to the mains (12). Switch on unit at
the mains switch (6). When the unit is switched on a self-
test is performed during which all display elements (2) are
operated briefly. The electronics then switches automati-
cally to the temperature and air flow rate set. The red dot
on the display (3) illuminates. This dot is used as visual
check on the regulation. Continuous illumination signifies
that the system is warming up. Flashing signals that the
