  DELAYED SUCTION: To eliminate the problem of solder clogging up the tip, a delayed switch 

feature has been incorporated for the unit that allows the pump to continue sucking for 1.5 
seconds after the actuator switch is released. 

  LIGHTWEIGHT SOLDERING IRON: Ergonomic mini handle that stays cool and prevents 

operator fatigue.   

◆ 

ENERGY SAVER MODE: If the station has been idle for 20 minutes, the energy   
saver  feature  will  automatically  engage,  the  temperature  goes  down  to  150

  from  the  set 

temperature  for  Soldering  and  200

  from  the  set  temperature  for  de-soldering  Activating  the 

solder/desolder  wands  will  disengage  the  power  saving  feature  and  the  unit  will  immediately 
ramp up to the preset temperature. When over 40 minutes without operation the main power will 
be switched off to “sleep mode” which cuts power consumption and extends tip life.   

Please  note: 

You  have  to  turn  off  the  power  switch  first  and  then  switch  “ON”  again  to 

commence work when the unit goes to “Sleep” mode.

   

  IRON WORKING OPTION: When the users don’t use the soldering or desoldering function ,or 

they also set by pressing keys “ SET 

+ ▲”,

at this time, the iron which you set will enter the 

power off suspend status. It means that the heater power is cut off.    If press “

▼”then 

the heater 

power will be on.

 

  OPTIONAL SMD TWEEZERS : The additional feature is specially designed for SMD chips, 

SOT, Flat pack ICs’ etc. reworking. TWZ90 Tweezers can be interchangeable with soldering iron as 
an option. Be sure before proceeding this operation, the main switch must be “OFF” to avoid any 
damage to the unit.   

 
Hot Air Funciton 

 

  With the high power heating element, heat up quickly, the momentary power can reach 600W. 

  Temperature adjustable, suits for removing QFP, SOP, PLCC or SOJ chips etc., 

      especially the built in static free circuit design is safety for the sensitive elements like CMOS ICs. 

  SENSOR /PUMP FAILED DETECTION: If sensor circuit failed that the display read “S--E” and 

cut off the heater power. If the pump circuit failed that the display read ”P-E” and cut off the 
heater power. 

◆ 

Auto-cooling design: When the power switch off, the cooling system will begin to work 
automatically, the temperature falls down to 100

℃(212℉) 

to protect the heating element from 

burning ..

 

  Heating element auto-protecting function: When heating element reaching a high               

temperature which can be protected automatically, to lasting the life of heating element.
