Thanks for the tear down. I have the 858D version that I've been using for years. I've not however done a temperature check to see if it's in spec.

Using a hot air rework/soldering station now that while nice on the outside ended up being mostly used parts on the inside. Found that out once I had an LM324 fail inside the device. Lucky for me it failed open so I didn't end up with a fire. I've since added a hard power switch to the device which only had soft off previously. Edit: I forget the date code on the LM324, I just remember it was very very old.

Have a similar Atten branded unit, it works just fine for home use. I've had it for 7-8 years without any issues.

I have taken 5 or 6 of these 858 hot air guns apart, the grounding has always been really dodgy in the handle. On all units the ground wire has always just been twisted onto a stainless steel strip that goes to the metal shield. The ground lead that goes to the handle is also too thin to actually reliably cause a fuse to blow in case of ground failure.

There's "inexpensive product" and then there's "knockoff"... The "BAKU" logo is a copy of the Hakko logo with the H and O changed to a B and a U, down to using the Hakko font (like the A) and Hakko double-K...

My version of this didn't have hot-glue, so was nicer, but it burned out. Their firmware has terrible thermal runaway protection, at least on my model.

Why do you think the transformer is mounted crooked?

It economical until it quits early or bursts into flames. I'm guilty as charged for using this cheap stuff.

I'm surprised they needed a microcontroller alongside all that analog stuff. Surely a PID this simple could be achieved with just a few opamps?

It's probably cheaper to go for digital design instead of messing around with an analogue solution.

Why not implement it with vacuum valves, why stop there

What a rip-off of Hakko.

No one would have copied Hakko is they sell their equipment for a decent price. Hakko on the other hand sell their equipment for 900% of its production cost to pay for their SEO luxurious life in japan.
