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).
Measuring instrument which can measure the leak voltage, the tip-to-ground resistance, and the tip temperature.|
HAKKO FG-101can measure all the above items. (However, insulation resistance cannot be measured.)
|Inspection 1||Checking the leak voltage|
|Inspection 2||Checking the tip-to-ground resistance|
|Inspection 3||Checking the tip temperature|
