CARE OF TIPS
Ca Caution: The soldering iron can reach very high temperature. Be sure to turn the
unit off prior to carrying out any maintenance or trouble shooting steps listed below.
IMPORTANT - Remove the tip and clean after every usage or at least once a week.
Remove any loose build up in the tip retaining assembly to prevent tip freezing. The
solder tips supplied are iron clad pure copper and if used properly will give a long life.
1. Always keep tips tinned before returning to the holder, switching off or storing for
any period of time. Wipe only before using.
2. Dont keep iron set at high temperature for long periods of time as this will break
down the surfaces of the tip.
3. Dont give any excessive pressure on a tip or rub a tip on a joint. It does not
improve the heat transfer but only damages the tip.
4. Never clean the tip with abrasive materials or a file.
5. Dont use a flux containing chloride or acid, use only rosin or activated resin
fluxes.
6. If any oxide does form, it can be cleaned by lightly rubbing with a 600-800 grit
emery cloth, isopropyl alcohol or equivalent, then wrap rosin-core solder around
the newly exposed surfaces and heat, flood the tinned areas with rosin-core solder
after wrapped rosin-core solder melted.
NEW TIP
Used according to the following procedures if a new tip were installed at any time, it
will give the tip much longer life.
1. Turn “Mains power switch” to “ON” position and set temperature to 250
(392).
2. Flood the tinned surfaces with resin-core solder when temperature reaches 250
(392).
3. Set at desired temperature after warming for few minutes.
4. The iron will be ready for use once it reaches the preset temperature.
IMPORTANT - Remove and clean the tip daily. If a new tip is installed, remove any
loose build up in the barrel assembly, otherwise tip may fuse to the heating element or
retaining barrel.
MAINTENANCE
TIP REPLACEMENT AND DRESSING
Tip can be changed or replaced simply by unscrewing the knurled nut barrel assembly.
The station must be switched off and allowed to cool before this operation as damage
may result if the system is left on without the tip inserted.
After removing the tip, blow out any oxide dust that may have formed in the tip
retaining area of the barrel. Be careful to avoid getting dust in your eyes. Replace the
