3.
Install the soldering bit in the soldering pencil rod, wrap new exposed
plating surface of the soldering bit with the tin wire (above φ0.8mm)
containing rosin, and turn on the power supply of the temperature control
system.
-
Proper routine maintenance will effectively prevent the
soldering bit from non-wetting.
Service life extension of soldering bit
1.
The soldering bit shall be wetted with the fresh soldering tin after use each
time, so as to prevent the soldering bit from being oxidized, thus
prolonging its service life.
2.
The soldering bit shall be used at lower temperature as far as possible
when it is capable of working. Low temperature can reduce the oxidization
of the soldering bit and helps to weld the components.
3.
Flux with less activated rosin shall be used because high-content activated
rosin will speed up the corrosion of the soldering bit plating.
4.
When the soldering bit is not used for welding, the power supply shall be
turned off as far as possible to prolong its service life.
5.
When the soldering bit is used to weld the workpieces, the greater pressure
shall not be exerted because greater pressure is not equal to rapid heat
transfer. To improve the heat transfer, soldering tin melting must be used
so that a soldering tin bridge for heat transfer is formed between the
soldering bit and the welding spot.
