temperature will be reduced by 1/3, which prolongs the life of the tip. Activate the red
button on the handle in order to disengage the power-saving feature. The temperature
will now be increased until the preset temperature is reached.
DESOLDERING : 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 on a daily basis.
(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 "OPERATING PROCEDURE FOR DESOLDERING ACTIVITIES" when you wish to
replace the tip.
6. Common Causes for Tip Failure
- The temperature of the tip exceeds 410°C (770°F)
- The tip is not sufficiently tinned
- Wiping the tip on a surface with a high sulphur content or on a dirty or dry sponge
- Contact with organic or chemical substances such as plastic, resin, silicone and grease
- Impurities in the solder and/or a low tin content
7. Maintenance Tips for Tips
The desoldering iron uses extremely high temperatures. Make sure that the unit is switched off
for maintenance purposes.
Remove the tip and clean it after heavy or moderate use. We recommend cleaning the tip daily
if the desoldering station is used on a daily basis. Remove excess solder in the tip retaining
assembly to prevent the tip from clogging.
The supplied desoldering tips are made of copper covered with a layer of iron. They will retain
their projected life span if used properly.
- Always tin the tip before returning it to the holder, prior to turning off the station or to storing it
for long periods of time. Wipe the tip on a wet sponge or use our tip cleaner (ref. VTSTC)
before activating the device.
- Using excessive temperatures (more than 400°C or 750°F) will shorten the life span of the
tip.
- Do not exercise excessive pressure on the tip while desoldering, as this may cause damage
to the tip.
- Never clean the tip with a file or with abrasive materials.
- Do not use flux containing chloride or acid. Use only resinous fluxes.
- If an oxide film has formed, you should remove it by buffing carefully with a 600-800 grit emery
cloth or by using isopropyl alcohol and consequently applying a new protective layer of solder.
