2) Then tin the surface of both soldering and desoldering tips by applying a new covering of solder to
protect it.
3) You can set the desired temperature setting by pushing the “up” or “down” key. When the
temperature reaches to the desired temperature that the heating indicator light will be flashed on
and off to maintain the set temperature. The unit now is ready for use.
CUATION:
Do not touch any of the irons at any time while the unit is on or while it’s cooling as
they will still be hot.
IMPORTANT
DESOLDERING
1.
Only activate the vacuum after the solder has completely melted. Melting is
accomplished by moving the hot tip around the lead leaving visible melted
solder on the component side of the P. C. B.
See Fig. 1 & 2.

2. Release the vacuum switch only alter the solder on the tip has been removed, otherwise the tip
may clog.
3. Add solder to the joint of the component and allow the solder to melt completely for improved
desoldering.
4. Remove the solder collector and clean it after no more than 200 applications. However, daily
cleaning is strongly recommended.
5. Replace the cotton pad in the solder collector and the in-line filter when they begin to turn
yellow.
6. If there is insufficient vacuum, use the spring wire included to clean the tip and also check he
in-line filters.
7. Be sure that all filters are in place during operation or damage to the vacuum pump may occur.
8. Follow the steps outlined in the OPERATIOING PROCEDURE section of this manual if a new
tip is to be installed.
COMMON CAUSES FOR TIP UNWETTING
1.
Tip temperatures higher than 410
℃
(770
℉
).
2.
The tip working surfaces are not tinned while the iron idling.
3.
Lack of flux in soldering, wicking, repair, and touch-up operations.
4.
Wiping the tip on a high sulfur content, dirty or dry sponge.
5.
Contact with organic substances such as plastic, resin, silicone, grease and other chemicals.
