DEADLY WIRING FAULT ; Atten 858D+ Hot Air Rework Station
<< < (43/44) > >>
Joserrodz:
Hi! I just purchased a 858D Hot Air Rework Unit and I went ahead and checked it for safety. I just found a lack of ground to the rear metal cover and corrected it! I also found that my unit is “neutral switched” but I need some help to fix it! Will you reply with either written instructions or pictures as to what wires to switch among the PC Board and the On/Off Switch so I can fix it! Thank you !

I've recently  bought one from an Amazon shop, and had to check it because ground line was not protecting the gun.
The surprise was that the internal design is completely changed and now it has not any big transformer inside.. in fact is a nearly empty box with only a front pcb and the rear connector!!  :D
The ground problem was easy to solve.. the cable connecting the pcb board to the external plug was not properly crimped. Quality check in these products looks null. Now the metal part of the air gun is grounded, so I assume everything is as it should.

Interesting how the PCB has a JLCPCB order number in the lower left corner...

I recently got an 858D for use in USA 120v, im not sure if i got a safe one though, could someone let me know if its okay to proceed using this unit?

I do this kind of sanity check when buying mains-powered test equipment off of Ebay. Thanks for the reminder that poorly paid electronics workers don't spend much time worrying about the end user.
