I'm saying it could or could not work, they could be selling T420Ds as T420 right now.
But they can change that.
Because I'm reading the fine print and calling out the fact that hopes and dreams may work, but according to the fine print, it may not.
There is also a different firmware version available online for the T420 which was released recently.
So when those come into stock, it could be that some future reading sees your instance that they are the same and in fact not get what they thought they would get.

True, they might have changed just to place the T420D better and at a better price point.. but the video of the russian guy is about 3 months old, soo my hopes are up.
Just saw the T400 btw, they announced it recently. Seems really interesting, but I assume it will be much more expensive than the T420..

The T420 firmware is very new, so it is more likely you'll get the T420D the sooner you order rather than later.
I ordered T420 in December and got a box that said T420D and T420D station with a cradle missing from the box.
I asked the seller I wanted to buy from, apparently they are an authorized reseller.
They said, the t420 can be equipped with two handles/docks, but only one can be used simultaneously (I assume it's coded in the firmware).
T420 and 2 handles at the same time.

Please stick to facts and not just assumptions.
Bought a 420 two weeks ago , was in a 420 package but system says it’s a 420D
V1.21 produced 2023-11-20
But yes if there came a new 420 firmware it sounds like they plan to change that.
Luckily I’m not affected : )
Haven’t knowed that otherwise I had ordered a 420D. Doesn’t want two stands as I use one stand with T245 and T115 handle , the T115 hanging on the separate ordered rod with T115 bracket beside of the stand . Tool change is for booth. Main seating hole & that one at the rod are separated to each channel.
Anyone knows if there is a firmware version which shows real temp drop when starting soldering ? Doesn’t like that it shows always the adjusted temp instead of real drop , makes the graph useless but maybe when they showed it they got too many questions why there is such a big temp drop even if usual with low mass cartridges.
Anyone knows if there is a firmware version which shows real temp drop when starting soldering ? Bullsh** to always show adjusted temp at that graph.
Quite afraid of this shitty behavior which I also saw in videos on newer FWs on T3A, so is it really the case among all of the FWs? If you cool it down on a sponge, it remains still the same? Thx for the info..
Would be sad to see it also on T420.
Does anyone have the same issue?
Plus, I found some "hidden" menu. No clue what that could mean, but here they are..
Thank you for the detailed reply. I can safely say that there is no mechanical damage on the unit.
It might be that I am just very spoiled with silence and I've not used it in my "lab envoirement" yet. If other units have the same issue, then there is no point trying to swap my unit out and try other units..
Here is a video about that: https://www.youtube.com/shorts/Cui7suIONVU
Also; I tested a geniune JBC cartridge, but the displayed temp was higher than the measured temp (around 30°K difference). Did anyone else check and can compare?

Hi, I always liked the T3A station and its quick tip change plus fast heat up time but I have already read a lot of the faults that the T320 from AiXun has also inherited.
That's why I've decided on a T420 is for my hobby and I don't need two handles although in the future I might add one more for smd specific use with smaller tips.
But today I saw the T420 showing in the specs 200W as the T420D, T3A even the T320 are 200W, but in the T420 manual it shows 100W 🤷🏻♂️.
How can it be that all lower model supplies have 200W even the T420D but the T420 shows in the manual 100W.
I would like to be sure that I will have the same power as the previous stations, before I buy it.
Do you know if the T420 is just as powerful 200W as all your models?
Thanks.
Edit:
I have always suffered with multiview (multilayer) pads plus large ground points or on-board transformers both with older JBCs and with the Yihua 937D that I have been using for over 15 years, so I worry about power so I don't suffer with soldering like that again.

I built myself last year a power supply and mount a transformer almost equal to the T420D station two independent windings one of 15v 100w and another of 180w 24v and without load when I turn it on you do not hear anything but if you put your ear to the box you hear the hum, I expected noise is normal but use some rubber bands at the bottom with the screw through the center and another above is a huge washer that already brought but thick rubber that prevents vibration.
I haven't done a test with load but I'm sure the hum will increase (if I can, I'll do it and I'll let you know).
The source I built it because now everything is sold are switched sources and it is horrible the electrical noise that they put to test the projects that is why I ended up building one.
I had an older fixed one for a station and the hum was huge!
Anyway others who have it can confirm it.
In the video the cric cric that is not from the source I don't know what it will be, the nnnmn that is.
If you mean the one that sounds like a cricket, that's not it, it's something else, the one from the transformer is constant.
I've bought one from Tempered store (https://aliexpress.com/item/1005006458278878.html) and talked to the seller before purchasing. They told me T420 is upgradable to two handles and both handles work at the same time (basically T420D). Thats why I bought from them.
After receiving my unit I powered it on and the menu said T420D, after a teardown, on every PCB it says T420D.
