Re: Current through the soldering iron tip

ESD Safe is not the exactly the same as current leakage or as simply grounding the tip of a soldering iron. There is as special spec and requirements for it to protect sensitive electronic equipment.... like microprocessors and amplifiers used inside decoders. Remember seeing sparks from your fingers when handling wool sweaters in dry humidity conditions?  See https://en.wikipedia.org/wiki/Electrostatic_discharge.
BTW - When you use a grounded soldering iron make sure that whatever thing you are soldering to is NOT energized. Otherwise you are creating a direct path for current to flow from whatever source it is connected to by touching it with a grounded soldering iron.
