Use – desoldering
1. Switch the desoldering switch to "on."
2. Adjust the temperature.
a) Always adjust a temperature as low as possible.
b) To be able to precisely set the temperature, measure the nozzle temperature with a ther-
mometer and adjust the temperature regulation.
c) The temperature may be between 380 ℃ and 480 ℃.
3. Wipe off old solder on the nozzle in the central hole of the sponge. If the nozzle tip is stuck with
old solder, the tip cannot correctly heat up any longer. Coat the nozzle with a thin layer of new
solder to ensure optimal heating power.
4. Allow the tip to touch the soldered spot to melt the solder.
a) Never allow the hot nozzle to touch the board itself.
b) Ensure that the solder has melted properly. Partially molten solder obstructs the desoldering
gun.
c) Never try to move the solder by force. It moves very easily when molten. If it does not move
easily, this is a sign for the solder not having melted correctly.
5. After ensuring that all the solder has melted, suck it in by pressing the gun trigger.
a) Hold the trigger for another 1–2 s in order to be sure that no solder rests stay in the channel
and that all solder gets into the filter.
b) Do not leave any solder rests in the hole on the board.
c) After removing all solder, wait for the board to cool down to avoid any accidental desolder-
ing.
6. Clean the filter and regularly humidify the sponge during and after use to ensure constant effi-
ciency.
7. After work, switch off the desoldering unit.
8. Before storing the device, wait for the desoldering gun to cool down.
Note:
With the suction power obviously decreasing, clean the nozzle and heating element with the
help of the cleaning needle.
