Step 6.
It is now necessary to clear the solder plug that came with your new
Desoldering tip. The manufacturer dips each tip in solder to seal and protect the
tip from oxidation until it is put in service. Turn the SET to the Maximum setting,
480 degrees C. When the unit stabilizes push the trigger on the gun and the solder
plug should be vacuumed into the Solder Capture Container. If for some reason
the plug doesn’t clear, use the appropriate cleaning rod (A, B or C) from the
accessory kit that was supplied with the unit to gently push the solder plug free.
After the solder plug is cleared return the unit to an appropriate temperature
using the DOWN button. It is important to select a SET Temperature for the unit
that is high enough to do the job but not so high that the tip is put under
excessive corrosion risk or that the parts that you are desoldering are damaged.
Auto Tip Saver Function
As an additional protection against tip corrosion due to excessive heat the ZD-985
has a timed Auto Tip Saver function that drops the SET to 200 degrees C every 15
minutes. When this occurs it is only necessary to push the “UP”, “DOWN”, or
“C/F” button to reset the machine to your selected SET point.
