Maintaining the unsoldering gun

1. Checking and cleaning the unsoldering gun in case of an obstruction
   a) Plug in the power plug of the station, turn on the unsoldering 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.
   CAUTION
   Should the cleaning drill get stuck inside the nozzle, it could break or be damaged.

2. Check the nozzle for signs of wear and tear.
   a) Check the condition of the nozzle tip coating.
   b) The inner part of the nozzle and its surface are coated with a special alloy. If this alloy is damaged by high temperatures, the nozzle is not able any longer to heat up correctly and regularly.

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 unsoldering cannot heat up correctly any longer.

Checking the filters
a) The filters must be checked regularly.
b) If the filter cover has cooled down to the point that one may touch it, press the ejection knob
on the rear part of the gun and remove the cover.
c) Remove the front holder and filter spring to avoid damages and obstructions.
d) Remove the filter.
e) Exchange the filter if you remark one of the following changes:
• The filter is rigid and brittle;
• two thirds of filter spring are full of tin-solder;
• the filter spring is rigid and obstructed with flux and solder.

5. Securing the filter
   a) Attach the filter spring to the front holder.
   b) Attach the front holder to the filter cover, making sure that it is correctly oriented.

Working with the soldering station
Soldering

1. Put the on/off switch to the on position.
2. Use the control knob to set the desired soldering temperature.
3. Begin soldering as soon as the temperature desired has been reached. This is shown by the LED light above the switch flashing.
4. Use the on/off switch “Smoke Absorber” to activate soldering-smoke absorption.

Maintenance instructions for soldering tips

1. Temperature of soldering tip – High temperatures reduce the service life of the soldering tip and increase the thermal stress of the components during soldering. If possible, use the smallest recommended processing temperature for the individual tin-solder.
2. Cleaning – Always clean the soldering tip before use to remove redundant tin-solder and flux agent residues. To do so, use a wet and clean cleaning sponge. All residues found on the soldering tip can affect soldering and provoke a bad soldering result. To ease cleaning, we recommend the use of our tin-solder scrapers.
3. After use – Always clean the soldering tip and re-tin-coat it before switching off. This will protect the soldering tip from oxidation and increase the service life of your soldering tip.
4. Never leave the station switched on without being used during a longer period and with a high temperature. This would facilitate the oxidation of the soldering tip. Switch the device off  at the main switch if it is not used during several hours. If it is not used for a longer period, its plug should be unplugged.

Cleaning the soldering tip
Clean to soldering tip as often as possible (if necessary, every day) to increase its service life.

1. Set the temperature to pprox.. 250 ℃.

2. As soon as the temperature has stabilised, clean the tip and check its condition. If it is much worn or deformed, replace it.

3. If the pre-tin-coated part of the soldering tip is covered with black oxide, apply new flux-agent containing tin-solder onto the tip and clean it again. Repeat this until all black oxidised spots have been removed, then apply a new tin-solder layer.

4. Switch off the station and wait that the soldering iron cools down, then remove the soldering tip.
   Wait again that the soldering tip cools down.

5. Now you can remove residues, e.g., yellowish discolorations, with isopropanol cleaning agent.

CAUTION:
To remove residues, never use a file!
Unsoldering

1. Set the unsoldering switch to the “on” position.

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. 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 touch the board itself with the hot nozzle.
   b) Make sure that the tin-solder is entirely molten (partially molten tin- solder will obstruct the unsoldering gun).
   c) Never try to move the solder by force. It will move easily if molten, and its not moving easily means that the tin-solder is not entirely molten.

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 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 unsoldering.

6. Clean the filter and regularly humidify the sponge during and after use to ensure constant efficiency.

7. After work is done, switch off the unsoldering unit.

8. Before putting the device away, wait that the unsoldering gun cools down.

Remove the component to be unsoldered. Once the tin-solder molten, the component can be removed from the board with the help of the component holder.

Switch the device off on the main switch. After you have pressed the main switch, the device will be cooled down automatically. During this process, the handle and heating element are cooled by cool air. This process must not be interrupted by plugging off the plug; otherwise, the service life of the device will be considerably reduced.
Remove all rests of tin-solder. After you have removed the component from the board, all rests of tinsolder should be removed from the board with the help of an appropriate tool.
B. Soldering
Apply soldering paste. To solder the component (e.g., an SMD) to the board, you need an appropriate quantity of soldering paste. Soldering: Heat up the component and the line terminals.
Clean the board. After the soldering has been finished, you should clean the board and remove all flux agent.

C. Calibrating the temperature of the soldering iron
After replacing the heating element or exchanging the handle or soldering tip, the soldering iron should be re-calibrated.

1. Plug the 5-pin plug of the soldering iron into the matching socket on the soldering station.
2. Set the temperature to approx. 400 ℃.
3. Put the main switch to the on position and wait for the device to reach the temperature set. Remove the cover cap of the calibrating screw.
4. When the temperature of 400 ℃ has been reached (shown by the lower LED light flashing), measure the actual temperature at the measuring tip and use a small screwdriver to adjust the calibrating screw. If turned clockwise, the temperature will be increased, if turned counterclockwise, it will be reduced. Then re-fix the cover cap.

Should you use different soldering tips and require an exact temperature, it is advisable to realise one calibration at once, as the actual temperatures of the individual soldering tips might differ even with identical temperature settings.
D. Checking the 5-pin plug of the soldering iron plug for damage Should the soldering iron not work perfectly, you can proceed as follows to exclude a damage of the connection plug and to localise the fault: Remove the connection cable and measure the values of resistance between the individual pins. The below sheet shows the values to be expected normally.

| Spot| Resistance (0)
---|---|---
A| between tip 4 and 5 (heating element)| 1.7-1.9
B| between tip 1 and 2 (sensor)| 16-18
C| between pin 3 and soldering iron tip| < 2

• Should the values of A and B differ considerably from the ones stated above, replace the plug and heating element or sensor.
• If the value measured exceeds 2 Ω, the soldering iron should be cleaned with steel wool or sandpaper (s. Fig.).

Unmounting a defective heating element:

To replace a defective heating element, the soldering iron must be unmounted as follows:

1. Turn the fixing nut (1) counter-clockwise and untighten the cover of the soldering tip (2) and soldering tip (3).
2. Turn the nipple (4) counter-clockwise and remove it from the soldering tip.
3. Remove the heating element (6) and plug connection (11) from the handle.
4. Remove the base spring (5) from the distancing sleeve.

Any defective heating element can be detected with the following measurement of the resistance values:

• The value of resistance of the heating element (red) is normally comprised between 1.7 and 1.9 Ω.
• The value of resistance of the sensor (blue) is normally comprised between 16 and 18 Ω.

If the values measured differ from the once stated above, the heating should be replaced as follows:

1. Unsolder the contacts of the heating element and sensor.
2. Replace the old heating element with a new one. When installing, make sure that the cable have a convenient bending radius to keep the line resistance as small as possible.

Construction of different types of soldering irons:

(913 and 914 types differ from 907 and 908 types in the form of the handle.)

Troubleshooting

• Only perform maintenance jobs with the device being switched off and the power plug being unplugged
• The power cable and all electric or electronic components may only be replaced or repaired by a person trained in electrotechnics.

Is the current flow ensured? There could be a short circuit inside the soldering iron or heating element or an earth leakage to the heating element could have happened.
The heating LED light is lit, but heating up of the soldering tip is intermittent or absent.| There may be a wire break in the connection cable of the soldering iron or a defect in the connection plug of the soldering iron.
The heating element of the soldering iron can be defective and must then be replaced.
The soldering tip does not pick up solder.| The soldering tip temperature may be set too high and needs to be lowered.
The soldering tip could be dirty (see chapter “Care instructions for soldering tips”).
The soldering tip temperature is too low.| Is the soldering tip oxidised? (See chapter “Care instructions for soldering tips”)
The soldering tip temperature could need to be re-ca li brated.
