WORKING TEMPERATURE 

To meet RoHS requirements, the 60/40 solder alloys are not allowed in the production 
process. The lead free solder alloys require a working temperature of 30

 higher than 

previous generation electrical soldering. The working temperature of solder is detailed 
below and can vary from manufacture to manufacture. 

Melting point                                          220

                                   

Normal operation                                300-360

       

Production line operation                    360-410

   

When the iron’s working temperature is set within the parameters suitable for the type 
of solder being used, a good joint is assured. Too low of a temperature will slow the rate 
of solder flow while a high temperature setting might burn the flux in the solder and 
emit a heavy, white smoke resulting in a dry joint or permanent damage to the printed 
circuit board (P.C.B.) and may also shorten the tip life.   
 

IMPORTANT

: The temperature above 410

    is not recommended for normal 

soldering functions, but can be used for short periods of time when high temperatures 
are required.

 Please note

 that the lead free solder alloys require a higher soldering 

temperature which shortens tip life. 
                                     

  OPERATING INSTRUCTIONS 

● Ensure that the working voltage matches your power supply before beginning use. 
● Check carefully for any damage during transportation. 
● This unit contains: 
    1. Solder wand. 
    2. Iron holder with brass tip cleaner. 
    3. AC power cord with plug.
