Maintenance and inspection of station-type soldering irons
Soldering Station

HAKKO FX-888

For station-type soldering irons which have become mainstream products in recent years, it is recommended that the control dbe performed based on the leak voltage, the tip-to-ground resistance, and the tip temperature.
The reason for this is that even if the insulation resistance is measured; it will not show the safety at the device side directly because the inside is insulated with a transformer.
To prevent device damage and soldering failure, periodically perform the following inspections (daily or weekly).

Required tester Measuring instrument which can measure the leak voltage, the tip-to-ground resistance, and the tip temperature.
HAKKO FG-101 can measure all the above items. (However, insulation resistance cannot be measured.)

In addition to the following inspections 1 through 3, inspections which seem to be required during work should be performed and recorded periodically.


Inspection 1 Checking the leak voltage
Inspection 2 Checking the tip-to-ground resistance
Inspection 3 Checking the tip temperature
