RECOMMENDATIONS FOR USE
For soldering and desoldering
- Clean the contacts to be desoldered of dust
or dirt.
- Preferably select a temperature below 375°C.
Excess temperature may cause the printed
circuit tracks to break loose.
- The tip must be well tinned for good heat
conduction. If it has been inoperative for any
length of time, it should be retinned.
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.
2 When the solder liquefies, start gently to rotate
the desoldering tip so that the component'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.

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.
Soldering iron tip replacement
Use the tip removal device Ref. 0114108.
Remove the ring to release the tip.
Remove the tip by pulling the soldering iron
lengthwise, without forcing the element.
Insert the new tip and make sure that it has
penetrated fully home.

Desoldering iron tip replacement
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.

Rest the desoldering iron body in the tip
removal device and unscrew the tip to be
replaced, with the aid of the spanner
supplied (Fig. a).
Insert the thickest rod inside the desoldering
iron body duct (Fig. b).
