Does it have problems with temperature spikes when you touch ground with the tip? Aixun was hiding problems with previous models by showing no real temperature... Also voltage about 1 V with ripple was leaking through the tip, in other video it was almost 1.7A.

Does it leak to grounded surfaces like the other auxin ? 😊

*Solution to temperature spikes:* I have studied original JBC and Aixun t320 schematics, and found that the only way to get rid of temperature spikes on Aixun, is to ground the station through a 10-15 ohm resistor (should also work on T3A, T3B stations). This will completely eliminate temperature spikes. You will still have one volt on the tip, but it will be much less current flowing to the ground (if you touch the ground with the tip), it will be pulses of 30 milliamps instead of 1,2-1,4 amps. *It is also possible to reduce voltage on the tip and make current negligible with further modification.* For that we need to replace the 3 core handle cable with 4 core cable (possible to buy at AliExpress), fourth additional core needs to be connected to the cartridges outer shell/tip contact in the handle and other end needs to be connected to the ground at the station (to the real ground, not the ground after 10-15 ohm resistor from which station are grounded). It could be good if someone will verify that the resistor mod works on T3A, T3B stations (I have checked only on T320, because this station I own).

very interesting!

honestly the feature for changing temperature with the iron is pretty genius! Never seen anything like it but it makes a lot of sense. On my workbench I have the iron and control unit on the right side which means I either need to reach across with my left hand for change settings, put the iron down and use my right hand or try to change it with my right hand while also holding the iron which is what I often do but isn't really the safest

on some scenarios it's impossible to make the PCB "fully disconnected" from earth. I've been trying to use my T3A to de-solder SMD capacitors, using a second traditional iron. It's impossible, the temperature reading gets unreliable and the tip reaches 500C with 360C as set point. I am so unhappy with my T3A, I would not buy it again. I feel that this earthing issue is a major one. This seems to behave a little better but still I don't want to see 410C when I set 310C on the unit. I would also check the actual tip temperature when that happens: with the T3A they tried to hide the overshoot with FW 1.34 so who's telling us that this is not doing the same and they are also covering the power spike on the display? :) Thanks for testing the earthing issue I discovered on my T3A video review.

Why don't they just isolate the tip and then allow the user to decide how they want it done. On the Weller stations I bought for work there is a jack socket on the rear panel, the tip and earth connections are on this, so it allows you to decide if you want to short the tip to earth or as i always did was fit a 10K resistor to provide a bit of protection and stop the tip charging up with static etc. Also means if you want to work on live PCB's you can remove the jack plug and have a completely isolated tip. My home made Weller soldering pencil power supply has the tip earthed via an internal 10K. Not sure why they need all that information on the screen, I just want a soldering iron that does the job.

Stray voltages can easily produce massive measurement errors in thermocouples. Even more so when using a switch-mode power supply like this one. Depending on the circuit design, it may well be possible to fix that in firmware, by making sure you only measure with the heater off. And if not, filtering multiple measurements may be able to produce realistic numbers. The Pace station I have at work shows similar high temperature blips while heating up from cold, and that’s a top brand.
