WORKING TEMPERATURE
Soldering at the correct temperature is very important to ensure proper solder connections. If the
temperature is too low, the solder will not flow correctly and may cause cold solder joints, commonly
known as “dry joints”. If the temperature is too high, the flux will be burned and not allow the solder to
flow correctly. High temperatures can also cause damage to the PC Board and other sensitive
components. When the working temperature of the tip is set to the correct value for the type of the
solder being used, a good solder connection will result.
The most common solder alloys used in the electric industry are 60 % tin, 40 % lead (60/40).
The common tip working temperature of 60/40 solder is specified as below (this may vary from
manufacturer to manufacturer):
Melting point
419 °F (215 °C)
Normal operation
419 to 572 °F (215 to 300 °C)
Production line operation
608 to 716 °F (320 to 380 °C)
Desoldering operation for small joint
599 °F (315 °C)
Desoldering operation for larger joint
752 °F (400 °C)
