Manual

The most commonly applied electronics solder is the Fixpoint

® 

 leadfree solder wire of 

Fixpoint

®

 solder wire L-SN 60 Cu 2 (DIN EN ISO 12224-1) with a tin content of 60% (60/40 

solder). This solder is available in different wire diameters (0.56 - 1.5 mm). We recommend 

a solder wire diameter of 1 mm for electronics.

  Before using the soldering station the first time, burn the soldering tip free of 

  production residues and tin-coat it.  Therefor switch on the soldering station and 

  let some soldering tin deliquesce at  an approx. temperature of 200°C to a thin 

  connected film on the soldering tip.

The correct soldering temperature is crucial for the quality of the soldered spots. In 

electronics the common soldering temperature is 300 - 380°C. Too low soldering tempera-

tures lead to cold solder joints. At too high soldering temperatures the solder core burns in a 

way interrupting the solder flow. Moreover, there is a danger of damaging the circuit board 

and other components caused to these high soldering temperatures. Wipe the soldering tip 

directly before soldering with the moist cleaning sponge. Remains of incompletely vapou-

rised solder cores, oxides and other contaminations will be removed this way.and dissapear 

from the soldering spot. Before replacing the soldering iron to the stand after work, the 

soldering tip has to be cleaned again and be tinned with some new solder. It is important to 

hold the soldering tip always tinned because otherwise it will become passive after a while 

and disable to absorb solder anymore.

1.  Hold the cleaned and well tinned soldering tip, heated up to the set soldering tempera-  

  ture, to the soldering wire and to the spot being soldered. Now the solder core flows and  

  cleanes the surface of the metal parts being soldered and then the soldering tip in order  

  to make the electrically conducting connection. 

  The soldering time in electronics is not  longer than 2 seconds. A good soldering spot in 

  cooled status looks smooth and shiny  after the removal of the soldering iron. Poor, 

  defective soldering spots look dull, uneven and brittle after cooling-down. Beside the    

  application of unsuitable solder or a too high soldering temperature set, defective 

  soldering spots often occur due to too short or too long soldering times. 

  A soldering spot may not be heated too long. On the other hand do not take away the    

  soldering iron from the soldering spot too early, but only when the soldering tin flows like  

  bare silver. 

2.  After finishing the soldering, leave some solder at the soldering tip before placing it into  

  the holder and switch off the soldering station. The remaining solder will then be wiped  

  off the hot soldering tip by the moist cleaning sponge before starting the next soldering  

 operation.

6.5 Notes on Application:

The easy handling and the short heating time might lead to careless handling of the    

  soldering station. Avoid this behavior absolutely! In order to ensure risk free soldering for  

  users and protecting the soldering station from damages, follow the safety instructions  

  and warning notes in this manual as well as the valid national or european directives.
