Temperature Control
(Model 1655A only)
The Need for Temperature Control
Most servicing work requires the use of a
soldering iron. If the soldering iron is
plugged in only when it is needed, time is
wasted waiting for the iron to heat up. But
if it is left plugged in all the time,
oxidation quickly erodes the tip. Also,
soldering iron temperature varies with
line voltage. Some irons reach the ideal
temperature at 105 to 110 volts. As a
result, at 120 volts, some soldering irons
are too hot, which can more easily
damage components being replaced or
cause separation of circuit board plating.
