Desoldering station 1. Plug the plug of the desoldering gun into the appropriate socket of the desoldering station. 2. Connect the vacuum hose to the vacuum socket. 3.
Plug the plug into the station, making sure that the marks match. Fasten the plug by turning it clockwise. Basics • • • Humidify the filter pads before use to allow them to be very efficient. It is recommended to regularly re-humidify the pads. Clean the filter spring and exchange the filters when they are dirty. The solder channel inside the gun can be cleaned with the help of the cleaning needle if necessary. Initial operation 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.
Maintaining the desoldering gun 1. Checking and cleaning the desoldering gun in case of an obstruction a) Plug in the power plug of the station, turn on the desoldering function of the station, and wait for the nozzle to heat up. b) Wait until the nozzle has heated up completely before beginning cleaning. c) Clean the nozzle opening with the help of the cleaning needle. d) In case the cleaning needle does not penetrate the opening, instead use the cleaning drill.
3. Replacing the heating element a) Release the holder and remove the cover and tip. b) Remove the old heating element, place a new one. c) Replace the nozzle and cover on their correct places. Re-tighten the locking screw to prevent any air leak. In case the locking screw is not correctly tightened, the desoldering cannot heat up correctly any longer. Heating element Heating element protection Nozzle 4. Checking the filters a) The filters must be checked regularly.
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 thermometer 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.
