CARE AND MAINTENANCE
1. Tip Temperature : High temperature shortens tip life and
may cause thermal shock to components. Always use the lowest
possible temperature when soldering.
2. Cleaning : Always clean the soldering tip before use to remove
any residual solder or flux adhering to it. Use a clean and moist
cleaning sponge. Contaminants on the tip have many detrimental
effects including reduced heat conductivity which contribute
to
poor soldering performance.
3. After usage: Always clean the tip and coat it with fresh solder
after use. This guards against oxidation and pro-longs tip life.
4. System Care: Never allow the unit to stay idle at high temperature
for extended periods. Utilize the automated sleep feature to con-
serve energy, pro-long tip and heating element life. If unit will not
be used for long periods it is advised to power down the unit and
unplug from the mains.
5. Inspecting and cleaning the tip:
◆
Set the temperature to 250 o C.
◆
When the temperature stabilizes, clean the tip and check its condi-
tion. If the tip is badly worn or deformed, replace it.
◆
If the solder plated part of the tip is covered with black oxide, apply
fresh solder containing flux and clean the tip again. Repeat until all
the oxide is removed hen coat the tip with fresh solder.
◆
Never file the tip to remove oxide.
◆
Remaining oxides such as the yellow discoloration on the tip shaft
can be removed with isopropyl alcohol.
