Changing Tips
This operation should be
done while the tip is hot, at
a minimum temperature of
250°C, so that any tin left
inside is in molten state.
- Unscrew the tip to be
replaced, with the aid of the
spanner supplied.
- Fit the new tip, and tighten
up with the spanner to
achieve a good air tightness.
250ºC min.
Desoldering process
Use the tip model with a larger diameter than the pad to be desoldered, so as to achieve maximum
aspiration and thermal efficiency.
1. Apply the desoldering iron
tip so that the component
terminal penetrates within its
orifice.
After pressing the desoldering key there is a slight delay until the self-contained vacuum pump
stops, this is to make sure that the vacuum circuit is completely empty.
If any solder remains are left on any terminal after attempting to desolder it, resolder it with fresh
solder and repeat the desoldering operation.
2. When the solder liquefies,
start gently to rotate the
desoldering tip so that the
compo nent’s terminal can be
eased away from the sides.
3. Press then, not before, the
vacuum pump push-button
just long enough to aspirate
the solder.
