I just received one of these Aifen A9 Plus units and did some testing to check for voltage leak and grounding. The tip is indeed grounded, and I measured 0.012 - 0.14v AC and 25 - 150mV DC at the tip. The voltage readings at the tip seem to be consistent with what is expected for irons using a switching power supply design (instead of a transformer) like this one. I just thought I'd post my findings here since a lot of people are asking in the comments. Thanks for the thorough review!
Thanks for the Aifen A9 Plus review, mine just arrived and like you had a peek inside. My order arrived with an Australia mains cable which had the wall plug cable angled up not down! No problems these things happen... The final assemply department also incorrectly wired the mains Active and Neutral reversed from the back of the IEC panel mount connector. The error I uncovered was the output of the IEC fuse was not looped to the switch below, but was connected directly to the PSU with the black Neutral wire looped through the switch. Our local electrical safety regulator would have rejected this configuration. It took about 30 minites to rewire all the connectlions correctly i.e. the fuse outlet directly to the switch. I also need to sperate out the mains 240V AC wiring from the 24VDC wires! It is unacceptable and poor practice to strap the single insulated mains wiring with the 24V DC wiring. I also check the soldering iron tip earth, the mains earth is soldered to the main control board with a lighter gauge than I was expecting (less than 1 -1.5mm2), with a very small 4.7ohm 0.125W resistor connecting to the PCB ground and iron tip. This practise is non-conforming and needs to be fixed. Otherwise the feature packed unit works extramely well so far.
I been working with JBC stations for more than 15 years, but they never really did any upgrades on stations like more temperature memories, and easier and faster way of storing temperatures, and also with no upgrades they kept raising the prices. A handpiece (245) from JBC is 80,- Euros here in Germany, ....... I had the Aifen A5 including temp. control hand piece for 60,- Euros. And Aifen did the missing upgrades that JBC never did. I asked JBC many many years ago for upgrades like more temp. storage places, ......... nothing happened. Aifen now did the 4 temp´s, (I asked them for that months ago) and they have the super fast temp storage, plus the hand pieces with temp control. The only think I would like to see is a bit more heavy station shell, cause that is pretty light weight, and so can move easily. But now working daily with the Aifen stations since last year march, (having sold my JBC stations) I do not miss anything about the JBCs. Aifen is even a bit faster in heating I guess. 🙂
That is really great to hear - I don't have first hand experience with JBC stations but really love the design. The Aifen is a really great station so far!
Check the temperature adjustment, cause they tend to set that to about 30° C "plus". I did some check on my A9 Pro and the "lovely" A5s (nice to work with the A5 when using the adjustable hand piece) and on all of them the factory setting been 30° C plus! And that was too hot compared to measured real temperature. I put that to zero, and then it is fine. You can find the adjustment infos in the manual. My A9 plus will come to my place in the next days. I ordered it, cause I need 4 temp. settings for my work. Thanks for sharing this video! 🙂
Just laughing again, cause indicating the active preset button and showing the choosen temperature on the right side, been also my proposal I made last year, after working a while with the pro. I told them to put 4 temps, an indicator for the preset button, and the choosen temp. ha ha ......... so they listened to me as it seems!
@@flippedout Got my A9 Plus few days ago, and now I am working with it every day. It seems its even a bit faster heating than A5 or A9 Pro, and really like the "finally 4 temp settings" I needed so much. In my work I have to adjust the temp all few seconds sometimes, big fat soldering points on potentiometers, tiny little ones on small switches, very tiny guitar pickup wires, ....... and all these different situations within minutes. The 3 temps just not been enough, I always needed a 4th temp setting. Now this works like a charme, and I am really happy about that. And "no", I paid the regular price for it, ..... but I asked them, about some discharge, cause they used my input (I had sent them some more infos about possible improvements) to get the A9 Plus to production .... "3 euros" .... ha ha ha ..... lol! I decided to not even use the 3 euro coupon, and pay the normal price and feel better with that! The chinese are pretty funny sometimes, ..... and can also show a pretty ugly side very fast! Happened when I had problems with the A9 Pro ..... so always keep that in mind, when doing any business straight with chinese people!
Thanks for your feedback - to set the sleep temperature you just hold the CH3 key and turn the unit on. You can select 0,150,180, or 200c standby temps. I just left it at the factory default of 0 degrees because it heats up so fast.

@@LandiKd The A9 plus is the newest (2024) version. The main difference is that they incorporated the solder splash guards over the two tip cleaning areas. The second thing is that they updated the display and have 4 preset iron temps instead of 3 on the pro. I would recommend the plus over the pro but I’m sure both are fair.
I've been watching many options of soldering stations and thus look very promising. But i want to buy full set of handles and tips (3 handles - 9 tips) some link for that?
I bought the 3-pack too. This is the one I bought because it wasn't much difference in price from buying the 2 handles independently. The 245 handle in this kit doesn't have the buttons on the iron like the one that came with my station - but works fine. www.aliexpress.us/item/3256805409434892.html?spm=a2g0o.order_list.order_list_main.81.468f1802ySEIgO&gatewayAdapt=glo2usa

Any soldering station recommendations for someone that doesn't know how to bring the A9 Plus up to scratch?
Thank you for your video! This is first review on TH-cam

Yes you are right - I don’t remember off the top of my head but I did have to adjust the temp with a probe to make it more accurate .
Hi, is the AIFEN A9 Plus compatible with the original JBC handles ?
Thank you for your video

So glad you did - so far this is my favorite soldering station ever! Good feedback.

So it doesn't have proper transformer? Could you do voltages leak test. Thanks

Como va la prueba de durabilidad
Pls test Sugon T60 and T61

Did it deliver the heating power as advertised?
@@_adamalfath I haven’t measured it but based solely on performance I would lean toward yes.
Does it leak?
Cuál me recomiendan el a9 plus o a9 pro?
Hi, thanks. is the tip properly grounded?
Yes, mine was
