DEADLY WIRING FAULT ; Atten 858D+ Hot Air Rework Station
GEuser:
Ok , i now know too! ;D

Just got one of these, and tore it right the heck apart. I was very surprised that find everything in order. Fuse on the hot, mains connected correctly, and ground to chassis and to metal parts nozzle. The machine is labled YiHua, as are all the boards inside. The construction was a bit sloppily done, bit the solder connections all look good. I was somewhat annoyed at their propensity to use whatever color wire they had laying around instead of using some sort of logic. But at least it functions properly and probably won't kill me.
There was even a shiny holographic Q.C. sticker on the outside. Of course the sticker did say "Qenuine Q.C. Passed". I guess they spell "genuine" with a 'Q' in China.
Anyway, I had fun taking it apart, and I really appreciated this thread that helped me to look out for all the potential pitfalls.

Great. Hopefully the complaints raised here helped. Few reports of the main board going, or parts failing, so it suggests the supplier is decent, so all complaints focused on assembly; that should be easy to remedy, just tell the assembler foreman to insure the proper order and not let things slide.
Chinese stuff can be devious, those QC stickers could be just stuck there for marketing more than true QC. If you go to hardware stores in Asia, they sell QC stickers of all types in rolls for anyone to buy.'

Luckily you did your own QC thanks to the folks who have posted on various 858D threads that was sparked by Dave's initial purchase.
You may want to buy a spare heater element because they are not easy to find and there is no part number to reference, so ask the seller you got it from if they have any and get a few; I got 1 for $6 delivered. Enjoy.

They should really just offer it as a kit. What's the point of building it if you can't get it right. Get someone to write a crap assembly instructions let the internet refine the steps. And voila you got some nice kits for sale.

I think of all China brand equipment as kits, that's why the tear downs are invaluable, one can know what to expect. Why bother assemble the whole thing, its easier and faster to check the work and fix what needs fixing. Kits only matters if the owner is new to electronics and needs to learn as well as use the item.
If the Chinese can't write or hire someone to write a users manuals in English, instructions for assembly would likely be far worse.
