Always set the temperature to as low
as possible for the work being done.
CAUTION
Never insert the cleaning pin in the
hole of temp. control set screw clamp.
As this may result in damage to the
unit.
CAUTION
Desoldering
·The temperature control knob
can be secured by tightening
the temperature control set
screw clamp ("+ " screw) at
the top of the Hakko 470B unit.
·To more precisely set the tem-
perature, measure the temper-
ature at the nozzle using a
soldering iron thermometer and
adjust the temperature control
knob accordingly.
Set the temperature.
Clean the tip of the nozzle.
·Keep the solder-plated section
of the nozzle a shiny white by
coating it with a small amount
of solder.
We recommend the Hakko
191 thermometer or Hakko
192 soldering tester for
measuring the nozzle tem-
perature.
If the tip of the nozzle is
coated with oxide, the
nozzle's heat conductivity
will be lowered.
Coating the tip with a small
amount of fresh solder
ensures maximum heat
conductivity.
