Editing Soldering iron (section)

=== Electro-static Discharge ===
Not all soldering irons are ESD-safe.

Although some manufacturers' mains-powered models are built with the element shaft (and hence the tip) electrically connected to ground via the iron's mains lead,<ref>{{cite web |url=https://www.antex.co.uk/technical/faqs/ |quote=[It] is appropriate to routinely test mains powered irons and stations... Guidance values for the tester settings [include:] Earth Bond Test ... pass result: < 0.1 Ohm ... A higher reading (i.e. up to 0.5 Ohm) can still be regarded as safe because the earth connection from the plug to the element shaft is welded or soldered throughout... |title=FAQ's |publisher=Antex (Electronics) Limited |access-date=2018-08-28}}</ref> other models' tips may float at arbitrary voltages unless an additional grounding wire is used.<ref name="hackaday.com"/>
