4.
At this time, the hundreds place of LED displayed temperature is flashing.
Press “▲” or “▼” key to select the value. Press “SET” key to select the
digit place. Enter the reading value of the temperature tester; the value
entry method is the same as that of “General Temperature Setting”. After
the value is entered, press “SET” key. Then the calibration of soldering
iron temperature is finished.
5.
If there is any temperature deviation, calibration will be performed
repeatedly.
Note: It is suggested to use FG-100 white light temperature measuring
instrument to measure the welding tip temperature. If there is password
lock, the temperature cannot be calibrated. It is necessary to enter the
correct password to calibrate the temperature.
3.3.5 Usage Precautions of Soldering Bit
1.
Soldering shall be performed at low temperature as far as possible
(370-380°C). When lead-free soldering is performed, the welding tip
temperature shall not exceed 400°C. Experimental results show that when
the welding tip temperature exceeds 400°C, the service life of the welding
tip is greatly reduced. Taking the automatic welding testing of K-shaped
tip (knife-shaped tip) as an example, when the welding tip temperature is
increased by 30°C, the depletion rate is increased by about one time.
Because high temperature increases the erosion and dissolution speed of
the tin wire and the iron plating layer on one hand, and influences the
diffusivity and wettability of the molten tin on the other hand, the iron
plating layer of the welding tip and the tin form a compound to further
oxidize the welding tip.
2.
When lead-free soldering is performed, the temperature setting is very
important. Because of the difference on the size of welding portion, the
power and performance of soldering station, and class and line type of
soldering tin, the soldering temperature will be adjusted, and soldering
shall be performed at low temperature as far as possible. If the soldering
temperature exceeds 450°C, the oxidation rate is more than two times that
