1.

 

Always tin the tip before returning it to the holder, turning off the station, or storing 

it for long periods of time. Wipe the tip on a brass cleaner prior to use. 

2.

 

Keeping the iron set at high temperatures (more than 40

0℃ 

or 75

0℉

) will shorten 

tip life. 

3.

 

Does not use excessive pressure to the tip or rub the joint with the tip while 

soldering; it does not improve the heat transfer and may damage the tip. 

4.

 

Apply solder to the joint, not the tip when soldering. The flux is naturally caustic 

and thus will eat away the tip. 

5.

 

Never clean the tip with a file or abrasive materials. 

6.

 

Do not use fluxes which contain chloride or acid. Use only rosin or resin activated 

fluxes. 

7.

 

If an oxide film forms on the tip, it can be removed by careful buffing with a 

600-800 grit emery cloth, isopropyl alcohol or equivalent and then wrapping rosin 

core solder around the newly exposed surfaces. Coat the tinned areas with rosin-core 

solder after the resin-core has melted. 

                                     

                                                NEW SOLERING IRON TIPS 

Applying the following steps will lead to optimum life. 

1. Flip the “

TWZ / SIA” 

function switch on to the “

SIA

” position. 

2. Turn the main power switch to the “ON” position. 

3. Set temperature to min. then turn Coat the tinned surfaces with rosin-core solder after 

reaching 25

0℃ 

(48

2℉

). 

4. Set to desired temperature after allowing the unit to idle at 25

0℃

  for 3 minutes. 

5. 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 the tip may fuse to the 

heating element or retaining barrel. 

 

MAINTENANCE 

TIP MAINTENANCE AND DRESSING 

Tips 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 in place! 

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 this dust in your eyes. Replace 

the tip and screw back the knurled nut barrel assembly using only firm hand pressure to 

tighten. Pliers should only be used to tighten the nut to avoid burning your fingers, but 

care should be taken not to over-tighten as this could damage the element. 
 

GENERAL CLEANING

 

The outer cover of the iron/tweezers and rework station may be cleaned with a damp
