Thanks mnem for your extensive description of your KSGER T12 soldering station!
I ordered a KSGER STM32 V2.1s T12 OLED controller. So no worries 'bout that.. ![Phew :phew:](https://www.eevblog.com/forum/Smileys/default/phew.gif.pagespeed.ce.n2uLOVFYMP.gif)
As I wrote: I came across reports saying that this controller is sensitive to overvoltage.
When I have my controller I will check what it is and what it's capable of.
The tip of the T12 cartridges being actually fully isolated would make ESD compatible design of T12 soldering station easy! ![ThumbsUp :-+](https://www.eevblog.com/forum/Smileys/default/icon_smile_thumbsup.gif.pagespeed.ce._JElyJQqdB.gif)
Too late for me, I took the steep way...

The DC buck converter you used would have been enough me, too.
Anyway, my DC/DC converter is capable of delivering 4,5A continuously and 7,5A for a short time.
I expect short heat up times and good/fast heating when soldering.

I would have bought this one for 80€ pesos

I've soldered with different Weller soldering stations throughout the years and found them to be very good at their job.
Currently I have two WECP-20 and a EC 2002 "antistatic".
I noticed that I have three of them because changing the tip is a pita. These three soldering station eat up valuable space, their cords interfere with each other and I happen to use only one station regularly.
I've come to a point where it's clear to me that only for having it a little more easy to change top another tip by firing up the next station has come to an end.
The T12-based soldering station have caught my attention long ago; For me the T12 cartrigde with integrated heater (better/faster heat delivery to the tip) have the advantage of being able to be changed quickly by just unplugging and plugging. If one uses a silicone heat insulation pad it's possible even with hot tip -unlike the Weller with its srewed mechanism (pun intended).
After all that's been said about the Metcals I might consider them, too. -if one should come cheap one day.
