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

<< < (34/44) > >>

Halford:
well.... I got mine today, and found this while waiting the delivery.

I'm not expert and I'ld like to know if this is a good sign before opening the box.

I tested for continuity and found that only the ground plug pin has continuity when touching the gun tip or the metal plate under the gun holder.... does it count as a valid test for correct wiring?

thanks

Hal.

Not sure exactly what you mean.

I got one several months ago, but due to the year from hell only opened/inspect/test it last night.
In mine, the earth is not connected to the metal casing, there is an attempt to connect but paint and general shittyness reders it useless and in need of replacement. I will put in lead for the chassis and ring terminal to some freshly stripped paint.

The earth does connect to the metal barrel at the end of the handpiece, but this is of a very thin nature.
The earth in the handpiece is not so clear, it is connected but very thin. Once way would be to replace the entire cable from base to handpice with a multicore that is suitably constructed.

Only if you can pass 12-25A through it….. ( assuming you are in the UK)
The British Standards have all sorts of tests built in to catch this type of thing, but again……… if you buy from China or those shitty drug induced trolls selling on EBAY ,then you get everything you deserve.
A 100% seller rating  could mean 100% of the customers are dead and did  not get to complain.

Just received mine.

After I powered it on, it tripped the circuit breaker in my house after a few seconds. The heating element was red hot. I unplugged it and found a dead short between live and neutral on the plug.  :wtf:

Tore it down and realized that the barrel was also connected to the mains active.  :(

QC is atrocious on these things and I recommend that anybody who buys these things test them before powering them on.

kff:
I just bought the cheapest Youyue 858D+ on ebay ($41 shipped) and sure enough both the fuse and switch were on the neutral wire. I was about to start rewiring the unit when I realized that the detachable AC cable itself (110V, US version) was miswired -- hot male pin was connected to the neutral female one on the other side of the cable and vice versa. With another AC cable that I had lying around, the wiring is now correct.
