OPERATING PROCEDURE FOR SOLDERING AND DESOLDERING ACTIVITIES
GENERAL
1. Make sure the unit’s power switch is in the "OFF"-position.
2. Plug in the soldering and desoldering handpiece and connect the vacuum tube to the VAC-
connection.
3. Connect the AC power cord to the mains inlet.
4. Place the temperature control switches in the "MIN"-position.
5. Place the power switch in the "ON"-position and do the same for both the "SOLDER" and the
"DESOLDER" switches. Both pilot lamps will light up.
6. Tin the surface of both the soldering and the desoldering tip by applying a new protective
layer of solder.
7. Set both temperature control switches to the desired temperature 3 minutes after the station
is warmed up. The unit is ready for use when it reaches the preset temperature : the pilot
light will extinguish at this time.
REMARKS
♦
The soldering and desoldering irons can be used simultaneously.
♦
The energy-saving feature will automatically engage if the desoldering station remains
inactive for more than 15 minutes (indicated by the green "PAUSE" indicator light). The
temperature will be reduced by 1/3, which prolongs the life of the tip. Activate the red button
on the handle of the desoldering iron in order to disengage the power-saving feature. The
temperature will now be increased until the preset temperature is reached.
CAUTION
Do not touch the metal parts of the soldering or the desoldering iron while the unit is being used
or while it is cooling in order to avoid burns.
DESOLDERING PROCEDURE : IMPORTANT NOTES
(a) Do not activate the vacuum pump until the solder has melted completely. Melting is
achieved by moving the hot tip around the lead, leaving visibly melted solder on the
component side of the PCB.
(b) Release the vacuum switch when the tip is completely solder-free, otherwise the tip may
clog.
(c) Add solder to the joint of the component and allow the solder to melt completely for
improved desoldering.
(d) Remove the solder collector and clean it after no more than 200 applications. However,
daily cleaning is strongly recommended, especially if the device is used frequently.
(e) Replace the cotton pad in the solder collector and the in-line filter when they start to turn
yellow.
(f) Use the included spring wire to clean the tip in case of insufficient suction. Also check the
in-line filters.
(g) Make sure that all filters are in place during operation in order to avoid damage to the
vacuum pump.
(h) Read "9. Maintenance" when you wish to replace the tip.
