Dangerous Solder Station KSGER T12

Unfortunately that didn't work for me. I've just dumped it and purchased a hakko.

floobydust:
For V2.05 power supply, I would add a ground wire that connects PE ground from the IEC connector to the 24VDC(-), and it should connect to the metal case (I use the encoder mounting tab to solder a wire there) as well.

Thanks for the clarification! I did just that, and now i have continuity from the tip to the ground pin. Before I made that solder i measured current between these two points. The measurement read 0.1mA, so I guess the leakage current was just that.

floobydust:
The leakage current is small but the voltage high, you don't want to damage semiconductors when soldering them. If your work surface (i.e. ESD mat) is not at the same potential as the soldering iron tip, then the parts get a zap.
I'm not sure what china's problem is grounding things, they seem to prefer floating soldering stations as if PE ground in the country is unsafe.

McClane:
Hi everyone!
I just received my KSGER T12 with Power Board v2.05 and already grounded the enclosure.
I’m now wondering if I should also connect the tip to ground, and if so, how.
I measure around 15V AC between the tip and ground, so much lower than what others measured. With a wire between 24V DC GND and PE this drops to around 0V. With a 1MOhm resistor instead of the wire, it only drops to around 5V AC.
What would be your advice - leave as is, wire or 1 MOhm resistor?
Thanks!
