When not in use
Never leave the soldering iron sitting at high temperature
foe long periods of time, as the tip’s solder plating will
become covered with oxide, which can greatly reduce the
tip’s heat conductivity.
After use
Wipe the tip clean and coat the tip with fresh solder.
1. When soldering iron is used for the first time, you should pay attention to mon-
itor iron tip warming situation, wait until the temperature just melted tin wire, a
layer of tin on the part of the gold-plated iron tip,and then the temperature was
raised to the required temperature. Keep in mind when working iron tip should
be long-term with a layer of tin to protection iron tip,in order to achieve optimal
soldering function.
2. As an oxide layer on the surface of iron tip, resulting in false low temperature
soldering iron tip, unable to melt tin and the tin, in fact, at this time the heating
elements with the soldering iron is high temperature state. This happens situ-
ation not to blind the temperature rises again, the application of clean sponge
clear oxides, such as not clear, please turn off the power, soldering iron be dr-
opped to room temperature, with No.0 sandpaper accidentally cleared the
oxide, then repeat the operation of the first point iron initial use.
3. Please pay more attention soldering iron in high temperature work back into
iron holder, should be adjust temperature button below 250°C stand - by use,
stand-by time over 20 minutes, please turn off power. Otherwise the soldering
iron in a high temperature for long time. Because between iron holder and
soldering iron generate accumulated temperature, lead to heating elements
accelerated aging, soldering iron tip derivative oxide, directly weakened sold-
ering, severe will result in the connecting screw nut plastic melt of the handle
or heating elements short circuit.
4. If the tip deformation or the occurrence of heavy erosion, to replace the new
one. (Note: Do not use knife file remove oxides of soldering iron tip.)
5. Soldering, do not give iron tips too much pressure, this will not change the
thermal conductivity, otherwise will lead to iron tip damage.
