Caution; Description; Technical Data; Starting - Weller WMD 1S Operating Instructions Manual

Thank you for placing your trust in our company by pur-
chasing 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 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 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 devices
is not necessary since the integrated microprocessor auto-
matically recognises the connected device and optimises the
relevant parameters for optimum control. The temperature is
controlled digitally. The required process parameters for
temperature and air are entered via three user-friendly but-
tons (Up, Down, Air). Set value and actual value are display-
ed digitally.
With the hot air pencil temperatures of 50°C – 550°C can be
realised, on the connection of a soldering iron or desoldering
iron the adjustment range is automatically limited to max.
450°C. The achievement of the pre-selected temperature is
indicated by a flashing dot on the display. Continuous illumi-
nation signifies that the system is warming 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 nozz-
les and soldering bits are available which allow many diffe-
rent 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 charge. 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 con-
necting 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 desol-
derer 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, con-
nect 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 opera-
ted briefly. The electronics then switches automatically to
the temperature and air flow rate set. The red dot on the
