Someone questioned Weller and got a more detailed reply from a product engineer (specific to Australian supplied units).
Guess he didn't get the "don't say anything" memo:
Thank you for contacting Apex Tool Group.

None of the hand held line voltage soldering tools have fuses

That explains the bad feelings I've always had when using Weller, and why I have had it for so long

I wonder why (not really
![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif)
) there is not much info regarding CE/cUL certification in the reply Dave.
Since the products is UL approved/recognized, the product is essentially not allowed to catch on fire. I have done a lot of type test certification work, and performed UL tests for electrical shorts, open, etc. in circuit. Every once in a while a rep from UL would show up and demand testing of whatever the rep deemed a safety concern or of interest. We used gaze to test for ignition, and it could ignite even without the main component shooting out flames.

I am thinking a surge test (lightning strike) while powered on would be a great place to start. A bunch of positive/negative repetitive pulses might weaken the enamelled wire, causing a short?
I only have a 110V and a 220V handheld unit (now truly 'grounded' from usage

- was also missing in the first place), so I can't test for myself. Anybody?
It would also be quite interesting to know exactly which norm (CE/EN/UL) it was testet up against, though I am a practical engineer - not a laywer engineer.
If it is only to be used in certain conditions, I would REALLY like to know before I or others use it. I don't care if laywers fight in court, especially if I am in my grave, dead. (Say an utility fault where the mains live neutral suddenly has going missing - and mains voltage is now phase-phase, or 220V instead of 120V)
Thanks!
