of CSF (SMD desoldering plungers) and suction nozzles. The vacu
um is activated by means of a finger switch.
LR 21: Our "standard" soldering iron. With a power of 50 W and a wide spec
trum of soldering tips (ET series) this soldering iron can be used anywhere
in the electronics sector.
MLR 21: With its 25 W power and slim design, this micro-soldering iron is espe
cially well-suited for fine soldering work with a low heating requirement.
WTA 50: The unsoldering tweezers WTA 50 were specially designed for unsoldering
SMD components. Two heating elements (2 x 25 W), each with its own
temperature sensor, ensure constant temperatures at both ends.
LR 82: High-performance 80 W soldering iron for soldering work with high heat
requirements. The soldering tip is attached by a bayonet catch to ensure
correct position when using different tips.
WSP 80: The soldering iron WSP 80 is characterized by its capacity for reaching the
soldering temperature quickly and precisely. Its slim design and heating
power of 80 W makes universal usage possible - from extremely fine to
high-temperature soldering work. Work can be continued immediately after
switching soldering tips, since the temperature is reached again quickly.

3. Commissioning

Place the soldering tool in the holder. Insert compressed air hose with 6 mm outer diame-
ter in the quick action coupling for the compressed air connection (12). Provide supply of
compressed air with 600 kPa (87 psi) dry, oil-free compressed air. Plug the electrical lead
from the soldering tool in the 7 pole socket (9) on the front panel and lock. Position the main
filter (6) with the hose joint between the vacuum connection (8) and the vacuum connec-
tion on the desoldering tool. Check that the mains voltage matches that on the rating plate
and that the mains switch (1) is in the off position. Plug the control unit into the mains (10).
Switch on the unit at the mains switch (1). When the unit is switched on, a self-test is per-
formed during which all the indicators (2) are illuminated.
The temperature set (required value) and the temperature scale (ºC / ºF) are then briefly
displayed. The electronics then switch automatically to the display of the actual value. The
red dot (5) on the display (2) illuminates. This dot serves as an optical regulation monitor.
Continuous illumination means that the system is heating up. Flashing indicates that the
operating temperature has been reached. The vacuum necessary for desoldering is activa-
ted by the integrated finger switch on the soldering iron.
Setting the Temperature
Ordinarily the digital display (2) indicates the actual temperature. When the "Up" or "Down"
button (3) (4) is operated the digital display (2) switches to the display of the required value
currently set. The required value set (flashing display) can be changed in the corresponding
direction by repeatedly pressing or holding down the "Up" or "Down" button (3) (4). The
required value can be changed more quickly by holding the button down. Approx. 2 sec.
after releasing the button the digital display (2) switches automatically back to the actual
value. It is not possible to make changes to the setting on a locked soldering station (LOCK).
Standard setback
If the soldering tool is not used within a period of 20 minutes the temperature will be auto-
matically reduced to a standby temperature of 150°C (300°F). After three setback periods
(60 min.) the "AUTO OFF" function will be activated and the soldering iron will be switched
off.
Activating the standard setback function: When switching on the unit press the "UP" but-
ton (3) until "ON" appears in the display. Use the same process to switch the unit off. "OFF"
will appear in the display (state upon delivery).
The use of very fine soldering tips may have a negative effect on reliable setback function.
