has  

not

  been reached, the solder drain can become clogged. Then let the desoldering gun

heat up a little longer.

7. Make sure that the solder has melted before “sucking it up.” Not completely melted solder

clogs the solder drain.

8. Hold down the button for 1–2 s longer to activate the pump to ensure that even larger clumps

get into the filter and do not clog the solder drain.

9. Clean the filters and springs regularly to achieve uniform suction.
10. When having finished work, press the soldering iron on/off switch.

Caution: 

Follow the instructions and notes to ensure that your device functions properly.

Industry recommended values:

315–320 

 for ordinary solder;

340–370 

 for lead-free solder.

The operating temperature of the soldering iron and the desoldering gun is between
200 

 and 480

 

.

Due to the different heating elements and the size differences between the soldering tip
and the desoldering gun, the soldering iron heats up faster than the desoldering gun.
This is normal and does not indicate a malfunction of the station.

The temperature display shows fluctuations when you use the desoldering gun. They
are created by the draught when the pistol is operated.

Hot air safety function

The hot air function uses a safety setting that prevents the temperature from rising faster than 3  

s

.

This corresponds to the industry standard and prevents sensitive components from being damaged if
the temperature rises too quickly. This function is activated in the standard settings and can be deac-
tivated if necessary. Please follow the next steps to switch off this safety function:

1. Switch off the station and make sure that all function switches are set to off.
2. Hold down the following two buttons: hot air iron function switch 

(17)

 and desoldering iron tem-

perature setting 

(5).

3. Switch on the station at the main switch while you hold down the two buttons.
4. Release the switch when “SAFE OFF” appears in the display (the display appears in the tem -

perature and airflow display field of the hot air function).

5. The field above the word “SAFE” shows whether the function is switched on or switched off.

The system now switches to standby.

6. To turn the feature on or off, just follow steps 1–5.
7. The setting remains saved until changed again.

Hot air iron standby

The  device   has  an  automatic  standby function   which   ensures  that  the   hot  air  iron  is  switched  to
standby  when  in   the   holder  and   not  in   use.   In   this  case,   the  display on  the   temperature   display
changes from “C” to “d.” After cooling down, the system starts to cool the hot-air piston by blowing in
air at room temperature. The display field shows the word “cool” as it cools down. As soon as 90 

are reached, the air supply is stopped and the display in the field changes to “----.” The hot air iron is
now completely in standby. To be able to use the station again, simply lift the hot air iron out of its
holder.

Changing the hot air iron standby countdown

The device is set at the factory so that standby switches on after 15 min. You can change this with the
following steps:

1. While the hot air iron is in standby (display fields 

16

 and 

18

 show “OFF”), press and hold the

button to increase the air flow 

(3).
