KSGER T12 Soldering Station STM32 V3.1S OLED Display Electronic Controller CNC Aluminum Alloy Case DIY Aluminum Alloy Handle Equipments 110V 75W T12 Iron Tips K ILS D24

Works very well and easy to change out tips.

The D24 tip heats up from room temperature to 300C in 2 seconds. Has adjustable standby/on/boost temperatures. Nicely flexible cord. Well thought out software. I really like how you can see the actual temperature while it's sleeping. The software is Celsius only. For safety should probably set "12. Power On" to "Sleep" - it would be nice if that were the default. The REPLACABLE tool itself is very light and balanced, the rubber sleeve where your fingertips go is very good for your fingers without killing your accuracy - something I think those soldering all day every day probably very much appreciate. Contains a battery for the RTC and settings - it takes a few powered-on minutes to charge enough and keep it remembering. 2 different UI strategies - one of which has clocks. Has an internal fuse. Has an externally accessible fuse cabinet with another fuse marked F5AL250V. The brushed aluminum front-plate is pleasing. Beautiful internal construction. Encoder knob feels skookum. There's a jack in the back connected to the mains ground - I suppose it's for ESD mats, benches, wrist-straps, etc.

<edit 2024-08-30>The replacement unit I received from Amazon Prime was MUCH better, clean solder joints and not much in the way of leftover flux on the PCB.However, the 2.05 Power Supply board, unlike the 2.04 Power supply board in most of the previous versions of the KSGER T12 station is NOT wired from the factory to ground the TIP of the iron for ESD protection, and as far as I can tell the Controller PCB has a floating PE (Protective Earth) ground connection, meaning that the microcontroller chip and the OLED etc is NOT protected from static shock either.The 2.05 Power supply board in this unit HAS however improved on the design / layout of the 2.04 power supply board, addressing the safety issues commonly mentioned by YouTube reviewers like John Salt (@Rchelicopterfun) of the heat sink fins crossing right over a high voltage PCB trace, protected only by the solder mask.The Case is grounded to the IEC earth pin at a banana jack mounted through the rear panel. That's great. Albeit, the ground wire is a very thin gauge (thinner than you see in the product description picture here)As it stands, I tested with the iron running at 350C, and put a multimeter set to AC voltage on the tip of the iron, and touched it to the chassis ground lug, and read 70VAC on the defective one I returned, and around 58VAC on the new replacement.To test how much current might actually be conducted over a ground wire if I were to add one between the PE (protective Earth) pad on the PSU board and the PE pad on the controller board. I set the multimeter to mA AC and tested again, from the chassis ground lug to either the tip of the iron, or to the PE ground pad on the controller board (both the old and new units have the iron connector on that board with a bridged solder joint between the negative dc heater supply pin and the pin that is connected to the PE ground plane of the controller board) The good news is, I was seeing 0.1 mA or even a bit lower.I am thinking that a good mod would be to remove the two pin AMP header connectors from both boards, and solder in a three pin header with a three wire jumper.. Because RIGHT there where the two pin headers are soldered is a third through hole which IS connected to the PE ground plane on each board. That would be MUCH cleaner than soldering a wire between the two boards' PE pads..I am puzzled as to why this is not what KSGER did on this model.. It is a no brainer.. I tested with a wire jumper touching those unused solder holes under the edge of the two AMP headers and got continuity from chassis ground to tip that way..I think that this last mod would make this an even more compelling budget powerhouse entry into the direct drive cartridge tip soldering station game. All the safety issues sorted, PSU board redesigned, and only 75 bucks with three T12 Tips!The Hakko FX951 is three times the price and the user interface SUCKS. Does not have half the convenience features of the KSGER.. And either comes with one tip or none, But at least the FX951 has an ESD safe tip ground connection.With all that said, 58VAC at less than a tenth of a milliamp is not likely to destroy semiconductors in and of itself, it would just be the risk of a static shock... I still think this is a GREAT soldering station for a weekend warrior / hobbyist / home recording studio owner like me who is mostly going to be soldering up patch panels and XLR jacks and connectors and 1/4" plugs.. I LOVE the user interface, how quickly it comes up to temperature, how easy it is to twist the knob to the left and instantly put it into standby without waiting for the (adjustable) timeout, and the mercury as opposed to ball switch in the wand which kicks it into operation the moment you pick it up. Setting temp is a quick press on the encoder knob and twist to the temp setting you want, and press again. While using the iron, if you need a boost in temp, you can just twist the knob to the right quickly and it jumps to the boost temp you can set up ahead of time for the duration you chose.Worth a buy, but I would be over the moon if I didn't feel the need to modify the thing for tip ground.<end edit><original review before getting Amazon replacement unit>When I first got this Soldering Station I was very psyched to find that the latest power supply board was included, which has a new design that no longer routes a high voltage power rail right under the large rectifier heat sink. That's great as it was a sticking point for many of the previous versions of the KSGER T12 ksm32 stations that have been reviewed at length on YouTube in the past 4 years or so.It also has a chassis ground from the factory. Also great, It also has ground jack (my cursory research so far suggests it is not necessarily the best idea to use that jack for an ESD static mat and wrist strap for some possible safety reasons?)Anyway, pretty much all of the YouTube reviews and teardowns I had seen showed that the iron Tip was ESD safe (presumably) with the tip showing continuity to the Earth ground pin on the IEC power input.My soldering station does not have a grounded tip.Also, the specific one I got has some ugly and incomplete solder joints on pins 3 and 4 of the PCB board connection to the Iron connector.. As far as I have seen in a few EEVBlog posts and what I could spy from freezing frames on YouTube reviews, pin 3 and 4 are often bridged together, but as you can see in the pictures, mine appears to have a cold solder connection with an incomplete connection to pin 4.I heard some very mild low volume pop noises as he tip was first breaking in, and I assumed it was that break in period that I had read about, but now I am wondering if it might be related to the front Panel PCB and those solder connections..I am going to be returning this for a replacement for the bad soldering work alone, because I am not sure if the design of the newest revision still has a grounded tip for ESD safe PCB work or not.I will say, that the User interface, and the time to come up to temperature, the auto wake from standby temperature, and the really quick and easy twist the knob to the left a couple of clicks to force the wand into standby are all fantastic. It works really well and melts solder much better than the older ceramic heater / passive tip style soldering Iron I am replacing it with. The iron reacts right away to heat loss into heavier lugs on XLR connectors etc and keeps the solder flowing without fuss. Changing temp is super quick, click the knob in and turn it to the new temp..I am hoping the replacement unit will have cleaner work, and perhaps be ESD tip grounded as well, although that is not a complete deal-breaker for me if the actual design is intentionally not ESD tip grounded..I will update my review when I get the replacement unit.

I have several KSGER stations, and I wanted to buy another one so I could upload custom firmware that provides better stability and profiles for additional soldering tips and handles such as T210. This station is advertised as STM32, however it has clone MM32 that can't be upgraded. T12 handles and solder tips are Ok, but they are low power. You might want to look into purchasing a station stat supports T210 and T245 soldering tips. Otherwise, it isn't a bad station to have but get to know difference between versions and type of soldering cartridges available.

This item may or may not be a good unit. However it did not meet my needs as advertised. It states that I was controllable from 50degrees and up but in fact is only able to do 150degrees and up.
