Connecting mode of the functional ground wire
Schematic diagram of the soldering
This product uses 3.5mm grounding plug, which is provided with the following four kinds of grounding modes:
Hard
grounding
Equipotential
connection
Floating
connection
Soft
grounding

Before the 3.5mm plug is inserted, the ground wire of the soldering
tool handle is connected directly to the protective ground wire of
the power line.
After the 3.5mm plug is inserted, the ground wire of the soldering
tool handle is connected to the 3 pins of the 3.5mm plug.
When the 3.5mm plug is direct connected to the socket instead of
being connected to the lead wire, the soldering tool handle is under
floating state and unconnected with any ground.
When the 3.5mm plug is connected to the ground via 1MΩ or
150KΩ resistor, electrostatic discharge loop is formed.
When the equipotential connection mode is chosen: the ground wire can
achieve the related function via being connected to the pin 1, 2, 3.
