Desoldering Rework Station
Item: 4966/ZD-985
Description
ZD-985 is designed for lead-free desoldering especially. Its fast heat-up and
strong power are ideal for soldering / desoldering all types of DIP
components.
With reasonable structure, single-hand operation, and strong absorbing power
can be easy to remove the residual solder from the one-sided or two-sided PCB.
This tool is used in the fields of electronic research, teaching, and
production, especially in the repairing and desoldering of electronic
appliances and communications equipment.
1.1 Control Unit
The desoldering gun is controlled automatically by the microprocessor. 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 gun (ZD-552B)
ZD-552B desoldering gun with a power of 80W and a wide spectrum of soldering
tips（N5 series）can be used anywhere in the electronics field. The high power
and gun-type design makes this iron gun suitable for fine desoldering work.
The heating element is made of PTC and the sensor on the desoldering tip can
control the desoldering temperature quickly and accurately.

Operating Instruction
3.1 Place the desoldering gun in the holder separately.
Then connect the plug to the receptacle on the station and turn clockwise to
tighten the plug nut. Make sure that the power supply corresponds to the
specifications on the type plate and the power switch is in 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 briefly. The electronic system then switches on automatically to
the set temperature and displays this value.
3.2 The display and temperature setting
The digital display:
-
shows the actual temperature of the desoldering tip.
-
shows the setting temperature: Pressing the “UP” or “DOWN” button can switch the digital display to the setpoint display. The set-point can be changed for ±1℃ 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 the set temperature quickly.
-
℃/℉ display: Switching the temperature display from ℃ to ℉ by pressing the
“℃/℉” button and then the electronic system will display the actual temperature① and setting temperature② in ℉, and vice versa. -
When the actual temperature on the desoldering tip is less than the setpoint, “HEAT ON” will display and make the desoldering tip heat up.
-
When the absolute offset is more than ±10℃ 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 a stable situation, we should wait a moment to let the “WAIT” disappear. -
When an “ERROR” is displayed, there may be trouble with the system, or the soldering iron is not connected to the control system correctly.
Sleep Mode
The station will go into sleep mode if the desoldering gun is not operated in 15 minutes. The temperature of the tip will cool down to 200℃ and keep it during the sleeping period until the station is restarted. And the station will go back to its previous working condition after restarting. You can use the below methods to restart the soldering station:
- Power off the power switch then powers on it again.
- Push any key (If you do not pick up the gun in two minutes after pushing any key, the station will go into sleep mode again).
- Pick up the desoldering gun.
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℃（ 752℉）
when the power switch is on. Since mishandling may lead to burns and fire, be
sure to comply with the following precautions:
- Do not touch metallic parts near the soldering tip/ nozzle.
- Do not use this system near the flammable items.
- Advise other people in the work area that the unit can reach a very high temperature and should be considered potentially dangerous.
- Turn off the power switch while taking breaks and when finishing using.
- Before replacing parts or storing the system, turn off the power and let it cool down to room temperature.
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 workbench or otherwise subject the iron to
severe shocks.
Do not file 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.
The 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 the error-free and intended operation. Inspect moving parts for
error-free operation and that they don’t bind, or whether any parts are
damaged. Damaged safety devices and parts must be repaired or replaced by a
qualified technician, so long as nothing else is indicated in the operation
manual. Use only accessories or attachments which are listed in the operation
manual. The use of other tools and other accessories can lead to a danger of
injury.
5.5 Keep children at a distance
Do not allow other persons to touch or disturb the soldering tool or power
cord. Keep other persons away from the work area. Unused soldering tools
should be stored in a dry
location that is out of the reach of children. Switch off all unused soldering
tools.
5.6 Protect yourself against electrical shocks
Avoid touching grounded parts with your body, e.g. pipes, heating radiators,
and so on. The grip of the antistatic designed soldering tool is conductive.
5.7 Work environment
Do not use the soldering tool in a moist or wet environment. The soldering
iron should be placed on the holder after finished use.
5.8 Observe the valid safety regulations at your workplace.
Safety Instruction
- The manufacturer assumes no liability for uses other than those described in the operating instructions or for unauthorized alterations.
- 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.
