can confirm now using a usb c to usb a adapter on the power supply, and using a usb a to usb c cable, the iron turns on and works at full power with qc3.0 support
I don't get what's the point? Basically all A-C cables are QC, all C-C cables are PD. You've used C-A adapter + A-C cable? Which power source? Which adapter? Does it just dumb down Type-C to 4 wires electrically without logic conversion?

the xiaomi works with multiple phones that support qc3.0/2.0 In theory it should work with the ts80 too.
I have exactly that Xiaomi PD power unit and it's stock C-C cable and it DOES NOT WORK with TS80, the latter doesn't even turn on.
Xiaomi laptop and Xiaomi phones work though (they even report the quick charging mode somehow, I though it's just PD mode supported by those phones).

This is weird, article lists USB PD 2.0 and QC3.0/2.0 support simultaneously (isn't it supposed to be called QC4?) for the Xiaomi power source but I swear to god, phones work, TS80 DOES NOT. I don't know maybe it needs C-A "adapter" but hell knows which type of "adapter" your're using, there are a lot of those including full blown PD to QC power converters.

You can try hack: Add 5.1kohm pulldown resistor between each CC-pin and signal ground in TS80, this should make C-C cable (which follows spec) and C-psu (whic follows spec, but has also QC 2.0 / 3.0) to work. I have not tested.
Edit 2019-02-19: Clarification: Two 5.1kohm resistors, one from CC1-pin to ground and one from CC2-pin to ground. If it didn't come clear from above. And do not connect CC-pins directly to each other. This is a device so it needs resistor from both CC-pins as C-C cable has only one of CC-pins connected between cable ends.

Simplified:
Charger or anything having female USB type-C connector is not allowed to supply voltage on Vusb pins before connecting pulldown resistor(s) to CC-pin(s). C-A (and C-B) cables and adapters have a resistor (only one CC pin, value 5.1kohm pulldown or 56kohm pullup) telling if their type-C male connector of cable/adapter is power sink or source. type-C charger/psu detects this resistor and if there is power sink connected, then starts to supply voltage to Vusb.
(I skipped PD communication via CC-pins, b/c it is not relevant with TS80 or when there is type A or type B connector in game)

There was/is a lot of adapters/cables with wrong resistor or it connected wrongly. These can damage your devices!

I think it's possible to solder that resistor inside TS80, it's 12-pin Type-C connector definitely has those CC pins. Not sure it will work though I afraid to kill it maybe someone else tries.
Those CC pins are probably not even soldered because TS80 DOES NOT and WILL NOT (according to manufacturer) EVER support PD negotiation and PD power source.

I need some help - my TS80 shows 130-140 C lower temperature, than actual one. I read all the debug menu values, all seems OK, checked D25 tip (4.45 Ohm, seems to be in range), done reset and calibration few times already, changed firmwares. etc.

Looks like it is a hardware problem, temp sensor chip probably. I can do reflow of the board (also probably I can request change for iron from the seller), but:
- I do not know whether chips are sensitive on temperature (afraid to burn out)
- which one to reflow
- whether it could be possible to return TS80 after that and whether it will fix the issue.

Any advice?)))

I am looking for cable only, which comes with "pro" package. It's really good cable, so I would like to use it in other projects... does anybody know any part number of similar cable?

I'm interested too. Even the cable is not so good: resistance is high and conectors' shields aren't connected together  :--. Well, it's partially so flexible because no shielding (or so I assume - I haven't cut one to see inside).
I have seen Banggood selling the cable + the charger combination.
