E. Password Change Settings
1. Turn on the power and press the button for 1 time and then press the button
for 5 times after inputting password. The display shows “ PRE- ” and the “ - ”
flashes. Shown as Figure 7.
2. Press the desoldering station increase and decrease button to input the first
password then press the button for transposing, and repeat the process
above until finishing 4 password for the first time. Shown as Figure 8. Press the
button to repeat the process and input the password as the first time. If the
password input is not the same, please refresh the password and input the new
password and then select the same password for the last two times.
3. Press button for 2 times to select and set up other functions if you need. If not,
password change settings is finished after stopping operation for 6 seconds.
4. As for soldering iron parameter settings, please take desoldering station /high-
frequency soldering station parameter settings for reference.

. Soldering Tip Maintenance and Use
Soldering Tip Temperature
If the soldering temperature is too high, it will diminish the functionality of the
soldering tip. Therefore, choose the lowest possible temperature. This soldering
tip features outstanding temperature resilience with the capacity for rechargeable
solder at lower temperatures to protect temperature sensitive components.
Cleaning
The soldering tip should be regularly cleaned with a cleaning sponge. After
soldering, carbon compounds and oxides derived from the soldering tip's residual
solder will damage the soldering tip, causing soldering errors or a drop in
soldering tip thermal conductivity. When the soldering iron is used continuously
for long periods of time, the soldering tip should be dismantled once a week to
remove oxides. To prevent soldering tip damage, reduce the temperature.
When Not in Use
When the soldering iron is not in use, the soldering iron cannot remain in a high-
temperature state for long periods of time; otherwise, solder on the soldering tip
will convert to oxide, greatly diminishing the thermal conductivity of the soldering
tip.
After Use
Following use of the soldering iron, the soldering tip should be wiped clean and
coated with a new layer of tin to prevent soldering tip oxidation.
1. When the soldering iron is initially used, pay attention and check for
temperature rises on the soldering iron tip. Wait until the temperature is just hot
enough to melt the solder tip, coat the soldering iron tip with a layer of tin and
then increase the temperature to the desired temperature. Remember when
working that the soldering iron tip should have been coated with a layer of tin for
a long period of time to protect the soldering iron tip and thus be able to achieve
optimal soldering functionality.
2. If a layer of oxide appears on the surface of the soldering iron, thus making it
seem like the soldering tip is at such a low temperature that it cannot melt tin or
be coated with tin, both the heating core and the soldering iron will in fact be
extremely hot at this time. When this happens, do not blindly raise the
temperature. Instead, use a cleaning sponge to wipe away the oxide. If the
oxide does not come off, wait until the soldering iron temperature falls back
down to room temperature, then use sandpaper to carefully remove the oxide.
Afterwards, follow the initial steps in point 1 above for the use of the soldering
iron.
3. Note that after the soldering iron is used for high temperature work, when it is
returned inactive to the iron holder, the temperature knob should be turned to
250°C or below. When inactive for over 20 minutes, please turn off the power.
Otherwise, if the soldering iron rests at a high temperature for a long period of
time, accumulative heat will be generated between the soldering iron and its
holder, thus accelerating the ageing process of the heating core. In this state,
the soldering nozzle will derive oxide, directly diminishing soldering
