Desoldering Station
Part Number : SS-331BC-F
1. Description
SS-331BC-F designed for lead free desoldering especially. The quick heating and strong power are for convenient
and clear soldering / desoldering all types of DIP components.
Reasonable structure, single hand operation and strong absorbing power can be easy removal of the residual solder
from the one-sided or two sided of the PCB. This tool is used in the elds of electronic research, teaching and
production, especially in the repairing and desoldering on the electronic appliances and communication equipment.
1.1 Control Unit
The desoldering iron gun is controlled automatically by the micro-processor. The digital control electronics and
high-quality sensor and heat exchange system guarantee precise temperature control at the soldering tip. The
highest degree of temperature precision and optimal dynamic thermal behavior under load conditions is obtained by
the quick and accurate recording of the measured values in a closed control circuit, and this design is especially for
the lead-free production technics.
1.2 Desoldering Iron gun
Desoldering iron gun with a power of 60W (Heat up rating 130W) and a wide spectrum of soldering tips can be
used anywhere in the electronics eld. The high power and gun type design make this iron gun suitable for ne
desoldering work. The heating element is made of PTC and the sensor on the desoldering tip can control the
desoldering temperature quickly and accurately.
2. TechnicalSpecication
Rated voltage range AC220-240V; rated power input 140W; 50Hz.
3. Operating Instruction
Caution : Make sure that the four screws which are used to fasten the Diaphragm pump are removed from the
control system before use. Otherwise serious damages may be caused to the user and the system.
3.1 Place the desoldering iron gun in the holder separately. Then connect the plug to the receptacle on the
station and turn clockwise to tighten the plug nut. Check that the power supply is corresponding to the specication
on the type plate and the power switch is on the “OFF” position. Connect the control unit to the power supply and
switch on the power. Then a self-test is carried out in which all display elements are switched on briey. The
electronic system then switches on automatically to the set temperature and displays this value
3.2 The display and temperature setting.

Desoldering Station
3.2.1 Shows the actual temperature of the desoldering tip.
3.2.2 Shows the setting temperature: Pressing the “UP” or “DOWN” button can switch the digital display to
the set point display. The set-point can be changed for ±1°C by tapping the “UP” or “DOWN” button.
Pressing the button will change the set-point quickly. The digital display will return automatically to the
actual value and the iron will reach to the setting temperature quickly.
3.2.3 °C/°F display: Switching the temperature display from °C to °F by pressing the “°C/°F”button and
then the electronic system will display the actual temperature (1) and setting temperature (2) in °F,
and vice versa.
3.2.4 When the actual temperature on the soldering tip is less than the set-point, “HEAT ON” will display and
make the desoldering tip heating up.
3.2.5 When the absolute offset is more than ±10°C between the actual temperature and the set-point on the
soldering tip or the nozzle, “WAIT” will display. It means that the temperature electronic control system
is not in the stable situation, we should wait a moment to let the “WAIT” disappear.
3.2.6 When “ERROR” display, there may be a trouble on the system, or the soldering iron is not connected to
the control system correctly.
4. Safety Instruction
4.1 The manufacturer assumes no liability for uses other than those described in the operating instructions or
for unauthorized alterations.
4.2 The operating instructions and cautions should be read carefully and kept in an easily visible location in the
vicinity of the control system. Non-observance of the cautions will result in accidents, injury or risks to health.
5. Caution
5.1 The power cord only can be inserted in approved power sockets or adapters.
5.2 High Temperature
The temperature of the soldering tip will reach as high as around 400°C (752°F) when the power switch is on. Since
mishandling may lead to burns and re, be sure to comply with the following precautions:
5.2.1 Do not touch metallic parts near the soldering tip/ nozzle.
5.2.2 Do not use this system near the ammable items.
5.2.3 Advise other people in the work area that the unit can reach a very high temperature and should be
considered potentially dangerous.
5.2.4 Turn off the power switch while taking breaks and when nishing using.
5.2.5 Before replacing parts or storing the system, turn off the power and let it cool down to the
room temperature.
5.2.6 Warning: this tool must be placed on its stand when not in use.
5.2.7 A re may result if the appliance is not used with care, therefore:
5.2.7.1 Be careful when using the appliance in places where there is combustible material.
5.2.7.2 Do not apply to the same place for a long time.
5.2.7.3 Do not use in presence of an explosive atmosphere.
5.2.7.4 Be aware heat may be conducted to combustible materials that out of sight.
5.2.7.5 Place the appliance on its stand after use and allow it to cool down before storage.
5.2.7.6 Do not leave the appliance unattended when it is switched on.

5.3 Take care of your tools
Do not use the tools for any applications other than soldering or desoldering.
Do not rap the iron against the work bench or otherwise subject the iron to severe shocks.
Do not le the soldering tip to remove the oxide, please wipe the tip on the cleaning sponge.
Use only accessories or attachments which are listed in the operation manual. Use of other tools and other
accessories can lead to a danger of injury.
Please turn off the power before connecting or disconnecting the soldering iron.
5.4 Maintenance
Before further use, safety devices or slightly damaged parts must be carefully checked for error-free and intended
