Replacement for Gm 951 soldering iron or described in the topic

Hello, I looked through the posts about soldering irons for beginners and I became interested in GM 951, which is impossible to get in new Poland (I don't want to buy with ali), I also saw the cheaper Bakon 950d, I was also interested in:
yihua 992d 700W 100-480T Celsius.
or the like.

I need a soldering iron for amateur applications, mainly tht, less often smd. Hot air is welcome, as long as it is not at the expense of the heater. The price I can pay is PLN 350. I read a few topics but didn't find the answer to my question, once WEP is recommended, once zaxoins, the next time others say that these "75W" are around 50 in fact. I need a soldering iron that will live for some time and will not be used too often, of course I do not require that at this price I will get equipment for years.

Not so cheap and forgotten ... Quick 202D, 90W.
Cool, and very effective, thanks to high-frequency heating (probably 400KHz).
Possibility to set three "favorite" temperatures and assign them to specific (three) buttons.
Measurement of the actual temperature on the tip, good PID algorithm, thanks to which there is a small thermal inertia of the tips, all this does a great job, currently underrated. :-)

Characteristic

- High power soldering iron 90W.
- An integrated temperature sensor located at the very "tip" of the tip ensures quick reaction to temperature changes.
- Microprocessor temperature control.
- Precise PID controller.
- Very fast heating (high frequency 400 KHz) and thermal efficiency, ensures high temperature stability also during continuous soldering.
- The switching power supply of appropriate power used in the substation has short-circuit, overvoltage and overheating protection, and ensures reduction of losses in the core and winding.
On the other hand, the output power from the power supply is stable and does not fluctuate with changes in the mains voltage (supply).
- Locking the calibration and set parameters with a password.
- Input of settings and operation by means of three (programmable) buttons.
- Transition to "sleep" state or automatic shutdown after a programmed time.
- Adjustable upper and lower limit of the temperature deviation from the set value.
- An acoustic alarm is triggered when the limit is exceeded.
- Digital calibration and maintenance.
- Anti-electrostatic execution (ESD Safe).
- Large selection of quick-change tips.
- Fault messages in the display.
- Easy change of tips (and a large selection of them).
- Nice soft wire for the butt.
- Convenient stock.

The GM 951 station is another clone of the Hakko FX 951 and, like the original one, it uses a standard T12 stock and tips with an integrated heater. The price of the clones varies from PLN 200 + shipping to PLN 500 on Ali / Bang Good, it is also possible to buy on eBay. The original Hakko production station costs 1k PLN +. As the previous speaker, Lack wrote, stations that use solutions with a heating element built into the tip are much better than the older solutions. I do not recommend Bakon because of the poor temperature / power control supplied to the heater, which causes rapid damage to the heating element.

I will say so recently, out of curiosity, I ordered such a Hakko clone on the STM32 prock in the 2.1S electronics version (made by KSGER).

You can find a lot about this version of the station on Russian websites - especially when it comes to prock software (where someone wrote a crack to it). Stations on STC controllers (e.g. Quicko, etc.), which are less able to stabilize the temperature, are rather discouraged ...

The SMT32 station project itself is said to have been created quite a long time ago, some Chinese did it and shared the project. The firmware itself, after uploading it, required entering a license key (for which it took some little money) - of course, both the Chinese and the Russians dealt with it ... It was also supposed to be written by the Russians of some alternative firmware. The station itself has a lot of options, including the ability to save temperature corrections for different tips, etc.

Anyway, I also bought it a bit with the desire to play and create alternative software for it, as if the original ones turned out to be bad :)

In total, I ordered with several types of handles (including the fake Hakko FM2028) and some fake T12 tips (different types) ... we'll see what it's worth when it arrives :)

I bought everything in this store (I got the link on some Russian website): https://www.aliexpress.com/store/918038

I have the aforementioned Bakon and like most of these clones it is not an ideal ... but for the money I once gave for it on aliexpress, I cannot expect too much from her I don't know if the tips burn quickly - I only use "Spatula" tips for cleaning PCBs at BGA etc. so not very often and so far the tips I bought are alive ...

Regarding the GM 951, you can still buy it from the Chinese on Ali for about $ 60, but now it is probably called the FX-951 (only the Hakko inscription - as you can see, they are going all the way and do not care about anything)

Bakon has not damaged me yet. ;)

Let's not hide that in every station on T12 / T15, in addition to various elements inside,
I also have different algorithms, and there is no information about these.

Exactly and no one will write it, on the other hand, Chinese software is quite often in such cheap devices at a tragic level. However, regarding the software for the STM32 station, as I mentioned, you can find the topic of a Russian who cracked soft. He did disasseblations and described the soft a bit, unfortunately the computer on which I was browsing it crashed, so I have no way to provide links (at least until I can revive it) ...

I have GM951 for sale if someone would reflect, monthly, of course, from Poland and under warranty.

I have been using Bakkon for 2 months and compared to Pace there is no difference for me apart from the prices of the tips and the difference in buying the station.
For the Bakkon, I only had to buy a good butt plate, because the one in the set is good for occasional soldering.
Now I will buy a self-assembly kit based on the T12, because I have angular sockets on my desk and I am going to change one into a station.

As for the Bakon 950D, I have been using it for some time. However, now comparing it with the Chinese on the STM32, I must say that the Chinese is better at stabilizing the temperature ...

I bought a set to assemble in the QUICKO Store on Ali and additionally a miniature driver for lmv358 for / spare.
1) Could someone say whether the circuit on this oled board is sufficient for trouble-free operation on T12 / T15 tips: OLED Controller 952 ?
I took it without the housing and power supply and I use a branded 24V power supply from the printer.
The tip heats up to operating temperature in no time, out of any competition! However, the indications on the display can jump around the set one - I did not touch the hysteresis. At 200-230 degrees, the tip was able to stick to the path on the tile (little experience yet ). 250 and it gets comfortable. Rozlut is just like that from 300 degrees.

Now I have T12BL and T12K tips for harder work. This BL is a bit uncomfortable, it doesn't catch the tip practically, only 1-2mm higher is OK.
2) Recommend, some nice mini waves to the overall tht. Upp, Diolut recommends bcm 2 and 3 mm - not too big?
3) Is it possible to get T15 tips at a good price somewhere (Ali, PL).
4) What a cool stand for this stock, what I have Chinese or with 3 hands is a tragedy.

@pierotez

I will say this, I wrote in the thread about soldering irons on T12 not to buy with the controller on STC (https://www.elektroda.pl/rtvforum/topic3448871.html#17153215)
because stabilization is tragic from the descriptions of people ... Probably this is the problem ... on STM32 controllers it works without any problems and at least I do not have such problems as my colleague describes ...

As for the soldering irons, it's a tragedy ...
For the station described here https://www.elektroda.pl/rtvforum/topic3448871.html#17153215 and the Hakko FM-2028 clone stock, I bought a second stand for Weller LR21 (Weller KH 20) ... I could just test it with what I already had and it seemed to me the proven most sensible option ...

I have this one for '51 (STC15F204EA) and I'm happy with it. There is no implemented PID controller like those from STM32 and maybe it does not fully use the potential of T12 tips, but still it is very ok.

Well, when I chose this station on T12, I relied a little on Russian forums (these stations are very popular beyond the eastern border) and there this controller on STC was not described very favorably (everyone recommends the version with STM32) ... On the other hand, I am surprised that it is not they made a PID and you can easily do it at 51 ....
