DEADLY WIRING FAULT ; Atten 858D+ Hot Air Rework Station

<< < (11/44) > >>

saturation:
Sorry to hear.  I think I posted all photos of the key defects, as did tasman. 

If you have some doubts compare it to our photos and if you're still not sure try posting a photo of the same areas such as the PCB of the handle.  I think tasman showed it but check continuity with an ohmeter of the handle and the ground plug, then open the case and check continuity of any point inside the case and the ground plug; ideally it should be near zero ohms.

Yeah I don't have GFCI directly on my bench but down the line it's connected. It's saved me from seriously getting hurt when I do dumb things like short an IEC inlet with my hand...

alm:
Something is seriously wrong if you get shocked by an inlet.

FenderBender:
Something is wrong with me or with the inlet?

I didn't realize it was on and grabbed it by the back probably making contact with all three terminals. Not sure exactly what happened  but GFCI kicked in.

Kibi:
I took heed to the information in this thread.
My 858D+ arrived at work the other day, and since I have access to a PAT machine at work I thought I'd be responsible and give it a quick test.
It failed miserably. No ground to chassis. There is ground to the nozzle, but but it's over 1 Ohm, so the machine failed that part too. The 1 Ohm would be due to the relatively thin wires in the cable up to the hand piece.
I think just connecting a the chassis to ground will sort it out.
