Commissioning - Weller WMRS Mode D'emploi

WTA 50: The desoldering tweezers WTA 50 were
designed specially for unsoldering SMD
components. Two heating elements (2 x 25 W),
each with its own temperature sensor, guarantee
the same temperature on both legs.
LR 82: Powerful 80 W soldering iron for soldering tasks
with high heat requirements. The soldering tip is
secured by means of a bayonet catch, which
ensures that tips are always in the correct
position after a change.
WMP: The Weller Micro Soldering Iron WMP is suitable
for processing SMD electronics due to its mana
geable design. The short distance between grip
and soldering tip makes ergonomic handling of
the 65 W soldering iron possible when carrying
out very fine soldering tasks.
See Accessories for a list of other tools that can be
connected.

3. Commissioning

Assemble soldering iron holder, place the soldering tool in
the safety rest. Insert the soldering iron plug in the connec-
tion socket (12) of the control unit and lock by turning slight-
ly to the right. Check that the mains voltage matches the
specification on the identification plate and that the mains
switch (1) is switched off. Connect the control unit to the
mains. Switch on the unit at the mains switch (1). The unit
performs a self-test when it is switched on, whereby all
display elements (2) are in operation. Following this, the set
temperature (specified value) and the temperature version
(°C/°F) are displayed for a short time. After this, the electro-
nics system switches automatically to the actual value
display. The red dot (5) in the display (2) lights up. This dot is
used as a visual control check. When lit up permanently, this
indicates that the system is heating up. Flashing indicates
that service temperature has been reached.
Temperature setting
As a rule, the digital display (2) shows the temperature actu-
al value. By actuating the UP or DOWN button (3) (4), the digi-
tal display (2) switches to the currently set specified value.
The specified value (flashing display) can now be changed by
tapping or holding in the UP or DOWN button (3) (4) in the
corresponding direction. If the button is pressed permanent-
ly, the specified value changes in fast mode. Approx. 2 s after
the button is released, the digital display (2) switches auto-
matically back to the actual value.
Temperature decrease WMRP
Standard setback OFF setting (ex-works setting)
If the soldering iron has been placed in the safety rest, the
heating is switched off automatically. When the soldering iron
is then removed, the heating switches back on again. The set
temperature is reached again after a short time thanks to the
fast heating-up time of the soldering tip.
Standard setback setting ON
If the soldering iron has been placed in the safety rest, the
temperature is decreased automatically to 150 °C.
After 20 mins. (setback time), the heating is shut down com-
pletely (flashing line in the display). When the soldering iron
is removed, the soldering station regulates back to the spe-
cified value. The set temperature is reached again after a
very short time thanks to the fast heating-up time of the
soldering tip.
Activating/deactivating the standard setback ON/OFF
When switching on the unit, press and hold in the "UP" but-
ton (3) until "ON" appears in the display. When the "UP" but-
ton is released, the setting is saved. Same procedure for
switching off. "OFF" appears in the display
(ex-works setting).
Standard setback (function with optional tool, no WMRP)
Standard setback setting OFF (ex-works setting)
No temperature decrease active.
Standard setback setting ON
If the soldering tool is not being used, the temperature is
decreased automatically after 20 mins. to the standby value
150 °C (300 °F). After 3 x setback time (60 mins.), the "AUTO
OFF" function is activated. The soldering iron is switched off
(flashing line in the display). If very fine soldering tips are
being used, the setback function may be impaired. In this
case, the use of the WPHT switching holder is recommended
(see accessories).
Note:
The setback time can be set with the external input device
WCB2 from 0 to 99 mins.
