2. Commissioning

Place the soldering tool in the holder. Insert compressed air hose with 6 mm outer diameter
in the quick action coupling (11). Provide supply of compressed air with 400 kPa (58 psi) dry,
oil-free compressed air or nitrogen (N ).

Warning: When using nitrogen, attention must be paid to satisfactory room ventilation.
Plug the electrical lead from the soldering tool in the 7 pole socket (6) on the front panel and
lock. Connect the compressed air hose to the compressed air connection nipple (8). Check
that the mains voltage matches that on the rating plate and that the mains switch (1) is in the
off position. If the mains voltage is correct, plug the control unit into the mains.
Warning: Do not direct hot air soldering tools at people or inflammable objects.
Switch on the unit at the mains switch (1). When the unit is switched on, a self-test is
performed 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.
Setting the temperature
The digital display (2) shows the actual value temperature. By pressing the UP or DOWN key
(3, 4) the digital display (2) switches to the setpoint. The setpoint can be changed by tapping
or by firmly pressing the UP or DOWN button (3, 4) in the desired direction. Pressing the
button will change the setpoint quickly. The digital display (2) returns automatically to the
actual value approximately 2 seconds after releasing the button.
Adjusting the Air Flow Rate
The air flow rate required can be adjusted at the flow control valve (7). Turning the control
valve (7) to the left increases the flow rate. Air is fed to the hot air soldering tool as long as
the finger operated switch is held down.

3. Equipotential bonding

The various circuit elements of the 3.5 mm jack bush make 4 variations possible:
Hard-grounded: No plug (delivery form)
Equipotential bonding: With plug, equalizer at center contact
(impedance 0 Ohms)
Potential free: With plug
Soft-grounded: With plug and soldered resistance.
Grounding via set resistance value.
or No plug and separation of bridge B1 on the control board.
Grounding via RC filter 100 k ohms / nF

4. Instructions for use

External input unit WCB 1 and WCB 2 (optional)
The following functions are possible when using an external input unit.
Offset: The real temperature of the soldering iron can be changed by ± 40 °C
by input of a temperature offset.
Setback: Reduction of the required temperature set to 150ºC / 300ºF (standby).
The set-back time, the time after which the soldering station switches
into standby mode, can be adjusted from 0-99 minutes. The set-back
condition is indicated by a flashing actual value display. After a period
equal to three times the set-back time, „Auto-Off" is activated. The
soldering iron is switched off (flashing dash on the display). The set-back
or auto-off condition is ended by pressing a button or finger switch
pressure. During this process the required value set is briefly displayed.
Lock: Locking the setpoint temperature. Settings cannot be changed after
the soldering station has been locked.
