Re: KSGER STM32 T12 soldering stations
I measure Ohms between the tip and PE ground and do not run a soldering iron if I get open-circuit.
Another way is to measure ACV between the tip and PE ground when the PSU is on.
Safety-wise you are never permitted to lift entry GND, so a 3-prong IEC connector ground is good to use.
The DC jack input is usually for powering from a 19V laptop brick. Better ones are 3-prong, some with 1MEG resistor to GND.
The Aixun T3A units seem to be too cheap in quality and the H/W, S/W design is not quite sorted out, so people are complaining about them: https://www.badcaps.net/forum/showthread.php?t=123458
