working time, which minimize concern about the influence of heat on components 
and tip life 

 

  ENERGY SAVER: If the station is set to the auto sleep function setting mode , 

after the station has been idle for more than 20 minutes, this new feature will 
automatically knick in. the energy saver feature has engaged, decreases tip 
temperature and extends tip life.   

 

  ISOLATED IRON HOLDER WITH TIP CLEANER:    Made of low abrasive 

brass shavings instead of conventional sponges to meet RoHS requirement cleans 
better and no water is necessary. 

   

 

  LOW VOLTAGE OUTPUT WITH SAFETY OPERATION:    The power unit is 

isolated from the A.C. line by a transformer and allows 36Vac to drive the heating 
element. Solder wand runs from 36 Volts for safety and with 90W high power 
PTC heater for a super-fast heat-up and quick temperature recovery. The solder 
wand is attached with heat resistant, non-burning, flexible

 

6-wire cord.   

  ESD SAFE AND SPIKE FREE CIRCUITRY:    The “Zero Voltage” electronic 

switching design also protects voltage and current sensitive components (CMOS 
devices, etc.) against damaging current and transient voltage spikes commonly 
produced by less efficient, mechanically switched stations. 

 

  DETACHABLE AC POWER CORD WITH PLUG:    Engineered AC outlet for 

alternating AC power cord with plug and connector specially designed for 
individual CE countries requirements.   

 
◆ 

EARTH JACK: With a grounding connector, there is the possibility for a 
grounding of the wire strap if required. 

 

                             

     

       

PRODUCT DESCRIPTION 

LF-3000

 

electronically

 

high  frequency  soldering  station  with    specially 

intelligent chip microcomputer control designs was developed to meet the present and 
future Lead-free soldering needs of the electronic production industry and suitable for 
work  on  professional  SMD  electronics.  An  ergonomic  handle  with  shorter  distance 
between  heating  element  and  tip  gets  very  fast  heat  up  time  and  quick  heat 
compensation.  A  high-quality  sensor  and  heat  transfer  technology  ensure  precise 
temperature  regulation  is  essential  for  making  consistent,  reliable  soldered 
connections. The aluminum housing has the advantages of strong structure, good heat 
sink  and  effectively  resistant  of  electro-magnetic  interference.  It  provides  all  the 
benefits  of  temperature  regulation  and  connects  via  a  highly  flexible  burn-resistant 
lead, and can be easily adjusted in temperature.
