KSGER 858D Hot Air Rework Station Review 

858D hot air stations: amzn.to/4alNJ02

Thanks John, good honest review on the product. You explain the pros and cons thoroughly. By doing your suggested mods it becomes much more ergonomic and user friendly unit. I like the fact that you can take a product of good value and turn it into a highly functional one, for little money. I'm glad I stumbled upon your channel. I rang the bell and I am looking forward to your mod videos.

Just bought my KSGER Hot air station mostly based on your review and demonstration of the insides I hope I'm as happy as you. looks like a better built unit than some that I have seen.

I'm getting one of these soon and can't wait to see the mod!

holy shit someone who actually knows the name of that plug.

Hi John, just found your channel this week and am enjoying your videos. Your knowledge, explanations and timing are great. I just ordered one of these units a few days ago and I too was disappointed at the lack of the GX16 8 Pin connection, so I'm looking forward to seeing your next video on that. I hope you'll film the entire process and don't edit out any important steps for noobs like myself. If the modification process doesn't involve any serious machining of the case I might order the GX16 set too. Many thanks for the great info!

Good news, Ali sells it with a GX16 socket as a standard now. Thanks for the detailed video about this nifty little hot air station!

Excelled review, thank you. I was thinking buy one of this

Hi John, I have the same Auyou Station as you and wanted a smaller footprint. I Bought the Ksger T12 Iron about 6 months ago and like it a lot. I received the Ksger SMD Rework Station a week ago and it is significantly different from the one in your review. The menu is the same as yours but the inside is wired with a small 24 V transformer, a tack welded clock battery and no magnetic switch in the airgun. I am new to electronics so I can not describe to you all the differences. That being said the unit seems to work well . I appreciate your video and hope to see more from you.

Great video! Looks like a great product, but WTF were they thinking when they left out the stand? Just incredible...

hi, can i ask you some question above the hot air gun using multi meter to test it

there are actually 2 versions of this unit now. the new one doesnt screw to the bottom of the chassis they redesigned the board to slide in like the soldering stations. i just ordered one of those boards to compare to these units.

Now all we need is a bench power supply to match :)

the timer could help when removing an ic if you are having trouble pulling pads. help keep work consistent.

Hey John, I have the newer release of this unit and am quite happy with it (did not buy it as one complete set, purchased handle some time ago but now decided to buy the DIY controller unit - I have the matching T-12 soldering unit as well). The handle does not have the little NTC although the connection pcb looks similar to yours. I have set the controller to use the cpu temp. There is a wire in the handle as well as the connection to the controller but I can't find what the resistance value of the NTC should be. Could be between 1k and 100k I guess. How much would it differ between using cpu temp and NTC sensor in handle? Do you know the resistance value or maybe could you please measure it? I can't find it anywhere. Thanks a lot for your help!

Hi just an update for anyone buying one of these i received my one in the post yesterday. Before powering it up i would recommend checking the unit carefully as the fan in the wand was wired in reverse also there was no heatsink on the Triac and the soldering on same was shit plus the usual problem with the case not being grounded. Now that it up and running its a great little unit and performs very well. The unit i received was the REV 3.0 with the PCB mounted sideways and pre installed GX-16

Hi John, thank you for that review... I've seen this station listed for 220Vac/700W, so if we use it here in the US @120VAC, the power is greatly limited, right? thanks again!!

is it possible to use the t12 iron unit with/for hot air if i get the "blower" seperately? or would i need to make and flash a custom FW to be able to do it?

Hi John, can I use the "Cold End Adj" function to calibrate the airflow? Or maybe this feature is for something else?

John great videos. I purchased the DIY version cause thought it would be fun to put together. (That was a mistake as it was missing several parts.) The hot air gun i rediscover is wired completely different than yours any thoughts on how i could determine which wire is which for the placement on the board? Also could you tell me where you found the schematic for this unit?

How does it stuck up to the quick 861DW?

Hi John does this unit suffer the same as the T12 soldering station where the battery was being drained by the R10 Resistor

My Atten hot air station came with a UK cable, I could use the EU plug instead :)

I don't know if you see comments on older videos, but I have a question about the Ksger Hot Air Rework station. My new station System Info shows 160V 59HZ is that a problem? Other than that all appears to be working.

great review! now sure how to set the standby temperature or flow though... I obviously want it to shut off when it sits in the holder... for me it goes to 100% air flow and same temp (when I remove it from the holder it goes to the set fan speed, same temp) ... any ideas?

How would the KSGER 858D fair with iPhone repairs removing Nand chips and Basebands?

Hi John, Have you heard any reviews on the KSGER Hot Air Gun SMD 700w Rework Station GX16-8? It looks to have very similar specs to this 858D, though the circuit board is looking a little stubbier and mounted sideways - to allow for the GX16 socket. Appears very similar to your modded version, though still without a chassis earth, as appears to be the way on Chinese equipment.

For the Temperature and the comment, I’ll think you leave in ALBERTA I watch you from Calgary Alberta I’m thinking I’m not far away from you ✌️

Could these heaters be hooked up to KSGERs solder stations?

Make a video how it performs!

Maybe you want to warn people before they put the GX16 plug in. There will be a possibility to have line voltage on the open pins when the plug is not connected!

Great review, I purchased after being impressed with the t12 unit but sadly the smd unit lasted 6 months, a week after warranty had run out, the glass fuse blew so I replaced that and now it just flickers error every second. Upon looking at new listings it states wires need to be swapped in the wand handle and thermistor needs to be added, Banggood have not been helpful at all stating the machine is out of warranty period, which i do understand but revisions have obviously been made and no advice on how to either purchase a new wand or how to repair. As soon as it’s turned on the heating element gets scolding hot and seems temperature is not being controlled .. if anyone has any ideas I’d be very grateful. Thanks

No they did that for safety you don't want to put your hand in the connector when it's plugged in

hi. on mine the buzzer it's not working. Any aiders?

Would they work at 240V main ?

I know you just got the KSGER but seriously you should try out the TS100 iron or the TS80 they're both insanely good

Hello, I have a ksger air gun to repair. needs the value of resistors R12, R13 and the name, model of LEDs DP, D5 Thanks in advance !

bought it a month ago and last week the first problems appeared. The temperature goes way over the set limit and at about 450 degrees it shorts the line between ground and neutral. Still cant find anything online

Its hardwired so you dont get line voltage on exposed connector

Mine melted itself the first time I used it at 450 degrees and full fan for a minute or so Tube glowing orange was the first sign that all was not well - tip temperature wiring failed shortly after heating element burned itself out...so I suspect the wiring to the tip temp sensor was iffy causing the coil to burn out (due to it miss reading the silly high temps it was hitting) I am having a few issues sourcing a new element to see if anything can be rescued from the wreckage, so have ordered a new complete handle I am not convinced you have an NTC in the handle if it is the same as mine (which your images look almost identical) If you look at the other side of the PCB that interconnects the wires from the flex to the components there is no NTC on there and I haven't spotted one in the flex lead...which is mysterious as I genuinely cannot see one no matter how hard I look for it The unit I got was pre wired with a GX plug and mine is wired as follows...again I cannot even see any spare wires for an NTC mounted in the cable Pin1 (red) > AC240v heating element Pin2 (brown) > 24v fan + Pin3 (blue) > 24v fan - Pin4 (Green)> Green wire to ground the metal tube Pin5 (Yellow) > Reed switch Pin6 (White) > Reed switch and tip temperature Pin7 (Orange) > tip temperature Pin8 (black) > AC 240v heating element Really interested in which wires yours is wired into (and if you can show me where this NTC is supposedly mounted !) Of course without a working tip temp sensor I just get errors so I cannot even try and raise and lower the temp in the handle to see if the screen reacts to this mysterious hidden NTC

Thank you for the review, I was looking for a good affordable hot air station to do occasionnal work on electronics and you convinced me to get this one. Question: I look on the website and I was wondering what is the real difference bettween the DIY and the assemble kits are. Right now they seems identical (DIY price is equal to Assemble +Handle) but in the pictures the boards look different? Is it just an updated version or is one board supperior to the other? Thank you. Note: I do realise that the DIY needs to be assemble. I cannot understand why they would be the same price.

The electrical adapter doesn't even use the ground pin from the German plug. So you lose that if you use the adapter. I also did the same 8 pin GX16-8 on my rework station... I may buy one of the KSGER stations and wire my existing wand up to it. I'm trying to find the wiring diagram of the ones you can buy with the GX16-8 connector attached by default so I can copy that so if it ever fails... I can buy a replacement and I won't have to rewire anything.

Some kind of setup memories? Like "channels'

Cool, it's nice to stack up with the non-mini T12 soldering station:-) I wish both came with all silver look (without buying the combo one):-) I have the Quick 858D. I think separate is better than buying a combo one in most cases and if one breaks, it won't take the whole job down.

Wish you would have demonstrated some reflow work with it.

💪💪💪

That's a very nice "intro" but I wished you had used it and compared it to your AOYUE on some BGAs. Every time a watch a review of a hot air station with that handle and the integrated fan, it's meh. While the units with the air pump or fan in the base are regarded as superior.

Thanks for review, but daaamn, it's sold out. 🙁

It’s out of stock since more than week

your mod allows finger access to line voltage - not good ! plus if you short the pins while plugging in - bye bye triac!
