fields of electronic research, teaching and production, especially in the repairing and
reworking on the electronic appliances and communication equipments.
2. Controlling Unit
The soldering iron and the desoldering gun are controlled automatically by two
micro-processors. The digital controlled electronics, high-quality sensor and heat exchange
system guarantee precise temperature control of 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 work. Temperature range is 160-480
℃
.
2.1 Soldering Iron (ZD415)

can be used anywhere in the electronics field.
The high power and compact design makes it suitable for fine soldering work. The heating
element is made of PTC and the sensor on the soldering tip can control the soldering
temperature quickly and accurately.
2.2 Desoldering gun

can be used anywhere in the electronics field.
The high power and gun type design makes this 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.
3. Operation
3.1 Place the soldering iron and desoldering gun in the holder separately. Then connect the
plug to 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 on the “OFF”
position. Connect the control unit to the power supply and switch it on. 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.
