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

<< < (12/44) > >>

T4P:
it's due to the thin wires but hey 1ohm is STILL much lower then 10k ohms

akcoder:
I thought I would add my voice to the mix here. I received my W.E.P. 858D today. Like everyone else, my unit was miswired. However some of the more glaring problems others had were not present on my unit.

What was right?

* Properly switched on the hot leg
* The tip is grounded
* The case is grounded
* The fan wasn't butchered! No tool or cut marks on it
What was wrong?

* Fused on the neutral leg
* 1/8" (3 mm) diameter blob of solder in the handle underneath the pcb just waiting to come loose and short stuff out
* The solder on the pcb in the handle looked pretty bad, but that could be due to my lack of experience with lead-free solder...

If you see dull solder joints it's definitely bad joints, i have never seen a china brand product with lead-free

Fused on the wrong leg? That's what they do to save money,  >:(

When was the last time you bought electronics from China? They've been lead-free for years (RoHS), and leaded solder is becoming more expensive.

... It doesn't save any money. They probably do it because they don't care, as many countries don't even bother with with polarised connections.
