Any opinions on the Aixun T420D?
« on: May 29, 2022, 01:12:35 am »
This station seems to be new and it looks like it actually supports all three handles T210 T115 T245.
It also allows for two handles to be used simultaneously.

I found the station here: https://www.aliexpress.com/item/1005004320345359.html

The soldering iron holders are the same as the ones on the T3A and T3B but they come with an additional bracket/clip so you can hang your iron.
Can this bracket be purchased separately?

I will say that it's cheaper than I thought it would be.  The list price of $438 is more what I expected it to be, but $329 shipped with DHL is actually a really good deal.  However, I'm still a little concerned with Aixun's build quality and quality control.  The T3A&B were a little shaky when they were first released (especially the internal soldering), which seems to have improved.  The QC issues still remain though, which is overall easy to address if you know what you're doing.  Open the unit before you plug it in, clean up any stray solder, inspect the joints (around the power supply especially), make sure there's nothing rattling around inside, and expect a cracked inductor (and be pleasantly surprised if it isn't).  The handles themselves can also have issues.  Do extensive amounts of soldering with the cheap tips before you use good JBCs.  You don't want your nice new tips to melt down.  This unit is more complex than its smaller siblings, so opening it up and inspecting it may be a lot harder.  I do like that the cables all come out of the back, but I do wish they would've put the power button on the front though.  Aixun has shown that they are willing to support the firmware, and I'd expect this to be no different.  Overall, it's probably the top in Chinesium dual soldering stations, with a good price, and proven firmware support.  But you should expect to open it up and clean and inspect it before any serious use.

I would love to see a review of this station. I think an Aixun will be my next station to compliment my T12 ksger. The T115 tips are definitely handy for very small SMD components where even the smallest T12 tips are just too big.

It is between this station and the Aixun T3B! I would love to see the additional bracket from this station on the T3B!

Heh, I'm sure SteveyG will be all over this one.  However, if you already have a good selection of T12 tips, I'd say the T3A might be better for you.  The 245 system has the best selection of tips in the world.  The T3A will run your T12 tips, the 210 and 115 tips are kind of limited (more expensive too), and aside from a slightly larger tip-to-grip distance, there's literally nothing you can't do with the 245 tips.  However, I will say that I don't do phone repairs, nothing smaller than 0603, so I don't know if the lower wattage of the T115 is more appealing/less likely to lift pads than the T245 stuff.  So take that for what it's worth.

Honestly it is the size of the tips on the T12 which concern me the most. They are just too big. I was doing a repair the other day on a plastic connector on a phone pcb. There just so happened to be very sensitive components on the other side. Hot air was therefore not an option. Heating from the top makes the connector melt. Heating from the bottom will most likely damage some components on the underside.

It is possible to do the repair with a soldering iron, however even the smallest t12 tip is still too big for this component.

I have more than 30 different tips for my T12 iron so I do know which kind of tips I like.

There are many great tips for the T115. The issue is that they are expensive! It is possible to get 10 T12 imitation tips for the price of one genuine T115 JBC tip.

Heh, I'm sure SteveyG will be all over this one. 

I may skip this one - at £300 +VAT +advance handling fee it'll be around £385, more than a genuine JBC CD-2 station, so the attractiveness drops dramatically even if it does have two handpieces.
Willing to reconsider if I get requests though.

I understand.  I'm fine with the T3A myself, so my interest is minimal.  I was curious about the build quality, and someone else already has one on the way.  So that will get answered.  Your Aixun videos do seem popular though, and it would make a nice cherry on the sundae that has been the series.  But at the same time, everyone already knows that Aixun and KSGER (plus it's clones) are the go-to pocket-friendly solutions.

Yeah - it's not cheap, true. But the two handpieces make it attractive for me - I need 2nd handpiece. So I either buy 2nd t3b (which is not cheap either) or sell t3b I have and buy the "big one"..
Another option is JBC nano station but that's in 1200 Euro (+ VAT) range ;)

Alright folks, I'll take the first step and potentially waste €450 on the full set with all 3 handles (t245, t210, t115 wish me luck. Ill report back as soon as I get my hands on this thing.

I have one, and i'm very satisfied. it's a really good soldering station, it's really fast, calibrated just right out of the box, solid, stable, and very useful. It has nice stands, just like an original JBC, and much better than Sugon, I2C, etc. There is a cute display, very easy to read, but not so professional looking like an original one. Sadly, it has proprietary connectors, just like another clones.

Unfortunately, original JBC handles are not directly compatible with Aixun T420D.

The connector is different, but you can replace that easily.

Guys, if it's not too much trouble for you, check the contacts on the handle connector with a tester without installing a soldering iron.
Between which contacts is a jumper installed to determine the connected handle С115? ;)

no as far as i was told no you can not. you may be able to re wire the transformer but the 220v i was told directly by aixun uses a different transformer then the 110v ive already been through this with 2 different sellers myself. i had to get them to exchange them. if you open it up the trans may have both hookups but i dont believe it does. you can watch sdg's video where he does a tear down and shows you the transformer itself.

so i re watched the video and no its one or the other see here https://youtu.be/4dOrV8wTkaw?t=441

there is a resistor inside the handle on both the 245 and 210 that tell the station which handle is connected so i assume the 115 is the same way i can check one tomm to see

just to double check i opened one of our 110v units and the trans in there is a 110v only. so you do need either 110v OR THE 220v

Thank you. A seller on AliExpress was selling a T420D with two handles and six cartridges for $220 shipped but it was only 220v. Ended up paying $320 out the door for a 110v version. Of course it had a bad 245K cartridge. Worked for 10 minutes (maybe 30 seconds soldering) and went kaput.

Short answer is no. 

Hot air requires an air pump.  There's no pump in the unit so the handle would have to have a fan or pump inside it, and in-handle fans are typically trash.

They are making a hot air unit supposedly.  But as to when itll be released or what itll cost, no idea.

Good to know. Thanks. I bought the 2-channel unit specifically with the hope that small hot air handle may come into existence... its useful to have even just for silly things like heat shrink etc; even if it is not powerful enough to de-solder an IC...

T420D is in the house. So far i like it. Using a large chisel tip from JBC i was able to tin a 1/4" thick 4"x4" steel plate, so yeah enough power. The power graph is fun. Noticed that most of the time it is not running at 100%, suggesting that thermal transfer from the tip to the part being soldered is the limiting factor.

way to much imo. they will come down and prob even with free shipping if given a bit of time. the actual full msrp retail price is only 187.00. i have an order in for some of the 310d's but i have no received shipping confirmation yet. im hoping i will soon though i have 12 ordered (for the shop) but the 110v versions. ill keep you all posted on when or if they ship and ill ask if maybe i can do a discount or something (i doubt it though they are stingy with discounts but i will ask) i am also asking about becoming a aixun dealer here in the usa for the people here. and stocking the products.

I recently posted a full review of this station with English subtitles if anyone is interested. It is the best-made and most functional Chinese soldering station I have tested so far. I recommend it.

I'm thinking about retiring my rds80 and buying a station with active soldering tips, so i came across the aixun stations. Since I want to stay as flexible as possible, the Aixun-T420 would be the "better" option for me than e.g. the Aixun-T320, especially since it supports 3 different holders. But what I'm not 100% sure about is this strange ground problem that the Aixun-T320/Aixun-T3A have. Is the T420 also affected?

What i get from sdg video is, it happen when tip / ground earthed. So it will shorted voltage from thermocouple to the earth then affect the signal if temperature. He says it better use floating psu

Looking for some active tip soldering station and this one is on the top of the list, what about the handles, have anyone tried genuine JBC handles and tips on it, does it need some hacking or can be plugged without any modification?

Came to ask the same thing, I suspect it'll need a new connector.  I bought a genuine JBC T245-PA and used that on my Aixun T3A.  I've now ordered a T420 and I'd like to do the same for the 115 (using JBC NT115).

So I'm wondering if anyone knows what kind of connector is being used and what the pin out is?

EDIT: Oh you posted this a long time ago, ever get anywhere with that?

Hi all. I recently purchased the Aixun T420 single-channel solder station with a soldering iron holder. When using the C115 soldering handle and tip, I hear a clicking sound from the solder station when turning it on. This sound does not occur when I use the C210 handle and tip. Has any Aixun T420 user experienced the same issue? I suspect that this sound originates from the relay switching inside the solder station when adjusting the voltage for the new type of soldering tip, but I would appreciate confirmation from others regarding this matter. Thank you in advance.

T245 and T210 use a 28v winding and the T115 uses a 8.5v winding.  So the click is it selecting to the lower voltage winding.  You can see the windings here:

I ordered a T420 from an Aliexpress seller and realised the T420 IS NOT the same as the T420D


source

And this isn't just wording or mistranslation; there is a different firmware



I should call out that based on that press release from Aixun you need to choose carefully, because some people are throwing out info like the T420 is a "gentle" path to T420D.  That does not appear to be the case.

They only appear to release partial firmwares on their Github, so I doubt you can just cross-flash; hardware not withstanding, would be interested to hear if anyone has attempted this cross flash.  Since the full firmware is not available and the microprocessor is read protected I'm not going to risk throwing $200 in the water.

Hardware wise my T420 has T420D hardware, identical to SDGs.  I got some black painted philips screws instead of stainless allen key nuts holding things in place (yes, I pay attention to that level of detail).  Otherwise I couldn't spot a single difference based on what SDG showed.

Well keep in mind that they advertise a feature-set.  There is nothing preventing them from simplifying the hardware on the T420.  But for now, or at least the unit I got, the hardware is identical.  All the solder masks show "T420D" typically with "v1.0" or similar.

Do you have plans to purchase a soldering stand (my assumption is a left-sided soldering stand) and a different soldering iron handle, then use them simultaneously with another type of soldering iron to ensure this? I really want to do it, but unfortunately, my finances are limited at the moment.

My plan is to use T245 and T115.  I don't really see the point in T210 because I either want to solder really small SMD parts and for everything else I've been doing great with the T245.  Ofc many people could make the same argument for T210 and T115 but the T210 is a bit more power limited. (but I digress)

I ordered the T420 with a T115 handle.
I also ordered a genuine JBC T115 and T245 handle, so I'll be using those two.
I did the same conversion with my Aixun T3A which is using a genuine T245 handle, and the quality of the latest Aixun handles are a lot better, but I want the "genuine" JBC experience without JBC prices and I'm doing that using the genuine hand piece and tips :-//

I still have a Aixun T245 handle (from T3A), changed the connector and tested it on the T420.  The problem I'm having is, it seem you have to use the stand.  If you connect it via the stand, it works just fine.  If you connect it via the station directly you can't turn on the iron.  It is detected just fine but it is stuck in sleep mode.  And before you tell me I connected it wrong, or it is the wrong handle or or or.  I tested this in all possible configurations. T115 connected directly and via stand. T245 direct and via stand.  Only one at a time, more than one at a time, etc.  The results are identical no matter the configuration.  I could no doubt make something that connects between the station and the back of the unit to allow it to turn on without a stand but what I wanted was the T115 hanging down using those suspension hanger things and turning on and off if I take it off.



TL;DR: Yes I ordered an additional cradle so I can use T245 and T115.  When I have time I want to use a single stand with both T245 and T115 with T115 hanging and T245 in the cradle.

Pictures of the T420(D) stand.  I added the blue cable tie.  The slightly molten insulation on the yellow/green wire is my mistake, I reflowed a bunch of the joints on this thing taking it apart and that one wire got too hot.

More pictures of the T420(D) stand.  The first picture was before I cleaned it.  The PCB after cleaning off the flux had some bits of copper showing which I touched up with nail polish (last pic).

With both the T245 and T115 hand-pieces, all metal parts are at earth potential.  Including the outside of the cartridges.

T245 hand piece is 100% identical, wiring wise, to the JBC original hand piece.  I don't want to post someone else' pictures here without permission but google "T245 pinout" and you'll see it matches 100%.

This means you can use Aixun/JBC T245 hand pieces interchangeable between Aixun T420(D) and JBC stations

there is a resistor inside the handle on both the 245

Unfortunately, original JBC handles are not directly compatible with Aixun T420D.

Do you guys actually have this station?

I can't see that they would have changed this, there is no V1/V2 for T420D and the pin-out matches the standard JBC and the connector is the same.
At least for T245.
T115 for sure is different it has a different connector.
I don't have a T210 to test.

If you do have the station could you take a picture of your T245 hand-piece with the cover removed, where you had this resistor?

Another T420D stand PCB exists which is used with the T210.
Cross posting with permission from @breeze1113

So here are some pictures and cable color pinout to the soldering station and the pinout from the base to hand piece. Note: the black and the blue are shorted by the pcb. I don't know why t is so different the pcbs of the right and the left base. Maybe it is made to not connect for example 2 245 hand pieces( just an Idea). Maybe it could be helful for someone. At this moment I can only connect the t245 hand piece to the left side base and the 210 to the right one.

Based on this I also tested the T420.
Both AC/DC are at 0 volts when I measure to ground (measured with Keithley 2000 at fast speed, just in case).
But I was basically measuring 0.00<noise bits>mV.

Yes, the T420D doesn't seem to have any of the issues seen with the other units with tip voltage or strange behaviour on boards referenced to mains earth

Just found out about the t420 that it is indeed upgradeable to dual channel.

 " Support T245/T210/T115 three handles, standard package with T210 cradle, support upgrading to two cradles with two channels work together"

I think what you found out was about t410 series. I am going to order t420 and try out

Their official documentation says it is not the same.

Did you miss the part where I literally posted a screenshot of their firmware page?
Or their FAQ saying that they are not the same? (https://web.archive.org/web/20231229095732/https://www.aixuntech.com/newsinfo/Aixun%20T420D%20VS%20T420%20Soldering%20Station/)

At present they seem to ship out the T420D with single cradle, but the units are officially not the same.
They could decide to change that in the future.

If you get the T420 firmware you'd be screwed.
Since the T3A all Aixun stations ship with the microprocessor read protected.
So there is no way at present to cross flash even if you have the exact same hardware with the other firmware.

No, I didn't miss this, it was actually the reason why I double checked.. I don't know why they write that, but watch the vid above which @mebel shared.

The info is on their homepage under products -> soldering stations -> page 2 -> t420

I'll wait till monday and then place my order since the company I want to buy it from wouldn't ship on weekends anyway.

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.
And I found no way to switch between the T420D <-> T420 firmware.
So when those come into stock, it could be that some future reader sees your insistence 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..

I think I'm gonna wait for it to be released or at least tested by Steve or someone..

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'm very sure it'll be more expensive.
It looks interesting, but nothing there is what I'm interested in at present.

I wish they could bring and alternative to the JBC desolder gun.
Basically a clone of their pump; the JBC desolder gun uses the same cartridge as a T245 apparently.
The other feature that would be great is to support the JBC tweezers.

There is a video, quite old now, with MarcoReps where he confirmed the JBC tweezers are just T245 with two channels.
So in theory a T420D could already power a JBC tweezer if you get created with wiring.

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).

The thing is, they could make a whole bunch of changes to it actually.  Since the transformer will only be half as loaded now.  So I think until we get an official "T420" (with the T420 firmware); you should assume you could either get a T420D or T420D with T420 firmware or a T420 with totally different internals, fewer transformer taps and so on.  I mean they are trying to save pennies on these things.  So no limits to what they can leave out to accomplish that.

:palm:  :clap:

You have absolutely 0 authority on this forum and more importantly the whole point is to have open discussions, if people want to be informed.
Shutting down a discussion because it doesn't fit your narrative is fascist, maybe you should find a place where you'll be able to police what people can or can't talk about?

Pointing out the disconnect between what you assume you are getting and what the product facts STATE you are getting means YOU are making assumptions and the hardware.
You are assuming you are getting a T420D, when the specifications, new firmware releases and now resellers are saying that will no longer be the case.
Nowhere did they say "hey we are sending you a T420D hardware wise and it will be T420 firmware".
You made that assumption.

Next you'll link me to your Russian video again, and I'll say the same thing I've said before.
The firmware releases for T420 is new, it is not unusual for companies to send out a better product while working to release a lower cost variant of product.

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 rod with T115 bracket .

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.

And just if someone interested , from my tests the Aixun Handles and Wires have no ESD additives/ surface / threatment. The ESD Meter goes high after rubbing and the ESD surface meter shows nothing too. (Wrapped highly conductive foil with conductive glue around the wire at two locations and placed the surface sensors on the stand away flat end of it).

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.

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.

So did I get that right? You CAN use both handles (T245 and T115) simultaneously? They heat both up at the same time?

Yes at my station I could.
At menu it shows it’s a 420D even if I bought a 420 in a 420 package.

But maybe  they gonna change that and new 420 then can’t use booth channels at same time??
Usability then depends on how the switch function between handles is realized I thought.

Hi all, also yesterday pulled the trigger on T420 with one handle as I believe it's the best value for the buck for such station. Will post later if it is the "D" version or not but I don't really need it at the moment as I'm only hobbyist who loves to have quality gear  ;D

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..

I'm running the latest firmware and have a Hakko tip temperature measurement thingy.
I've tested with a T245 and T115 and both behaved correctly.
I am using genuine T245 & T115 tips and also using the original JBC handles for both.
Doubt the handles would make a difference, but the tips could definitely make a difference

Thx for the info, will inform how about mine when it arrives..

I agree the handle should not have big impact on the temp measurement as it's basically a copy of the JBC. Regarding the tip itself, yes, but even for the non-original one there is thermal sensing element, so while of course it can read wrong numbers, it should be noticeable when you cool id quickly down (ie in the wet sponge).
I have seen some videos with T3A featuring the latest FW (think it was 1.34) showing still the same set temperature whatever happened. Would be sad to see it also on T420.
