Warning: Check your Soldering Iron, etc

[BigJ]

Hi All.

Some info that may stop another DK member from going thru the same expensive nightmare I'm facing at the moment:

This is something that sounds simple and obvious, but I overlooked it and now Im sitting with a pile of damaged clusters, a damaged R260, UPA to name only a few.

Make sure your earth leakage trip switch is working 100%

I never noticed mine was not providing earth leakage protection and is ****ed untill my R260 programmer and a customer's cluster literally exploded in my face this weekend past.
Problem was in my SMD rework station: The braided earth strap in the hot air element was touching the element itself, which uses 220v. This sending 220v thru the earth wiring to all my electronics etc. But faulty earth leakage switch never tripped!

So the tip of my normal soldering iron was 220v "hot".

To make a long story short: The soldering iron was pumping +- 70v ac into anything I was working on that was not earthed.

When I earthed to another ground source, my R260 (after soldering the wires to the board) this weekend and did a cluster, my soldering iron touched a track connected to the black wire (ground) and BANG!

Suddenly I realised why I have a few clusters that dont work any more as well as other messed up equipment and pc's.

So go check your's is working as it should a.s.a.p.

What brank or rework station do you have?

[racin-snake]

hope its not an aoyue :afraid:

[daniersms]

Soeee not good can sustain injuries to your person aswell

Howdy Fallen.

Ive got a Gordak 952A. (Got a few actually).
They otherwise work very well.

Howzit daniersms.

Nothing like a 220v "skop" once in a while to get you going.lol

well if it makes you feel better was soldering a circuit board with the mains on & BANG.

then got a simular board to use to find what blew, then my test wire blew that board.

then was just stickihg a module back in a machine 2mm screw to long & BANG.

Feel much better now.... can lay off the Valium at last.

ON AND OFF TOPIC:-

If you buy a house in the big bad city, where the grass is green and the pritty *HOT* parts bird doesn't email you back, you can find a damp house, or even a very nice house in the country, the cooker can get damp, this trips the GFI (Ground Fault Isolator) - Emerican term.

What you do is, remove the earth off the cooker - stove if your Emerican - turn on, so it's hot, turn off, reconnect earth.

ON TOPIC:-

It is possable your iron the earth cable snapped?

Say catikid,

1) Put CHEAP gas in it.
2) Place the thing on a dashbaord with the exhaust towarsd the windshiled? What happens?:roflmao:

Hey now we got plenty in common...... Lots of my things are also powerless now. :dong::dong:

The braided earth strap in the hot blower front thingy attached itself to the element.

[Meat-Head]

who fitted the braid, you or Wan Kin from China?

Wan Kin: It came that way.........:ahhhhh::roflmao:

[Meat-Head]

just a thought, if groynded if live e fude fusse sodding fone fuse should blow. posd neutral switchted supply, full heat.

wounder if 'one hung low' didn bother with earth?

[BigJ]

Have had my workshop checked out and would so happen the wall plug socket plus a few others had a shitty earth on them.

Luckily Im insured, so lets see what still comes of this expesive saga.

[Meat-Head]

OFF TOPIC:-

theres a bunglow here in m/c which was built 199? if you look, you will see EVERY socket had the earth cut SHORT, hth no one knows why!

[ecufix]

Good point Bigj , as a further precaution rather disconnect any power from any board you want to solder on .

SECOND THAT - if it has mains on it then YES, unplug.

ERR hang on guys, i've got a great idea.

Just looking on a 'popular internet auction site' - just seen the handle, looks very much like the

Say BigJ can you pop here and have a snoop doggy snoop and racin snake please.

Thanks

Always use a safety transformer for your workbench!
And soldering irons of good quality also with safety transformers in it!
I was in the television repair bussines decades ago and then you learn the hard way...:mad:

Thanks for those links Meaty. Interesting site.

The Gordak is pretty close in design. From looking at the pdf, it uses exactly the same hot air nozzle.

Yup, we all gotta learn the hard way, even though we know better.

Thanks ecufix.

Wise advice.

For the record: Power was disconnected but USB cable was still plugged in to pc. Thats where it grounded.

Lesson learned: Unplug everything!!

Thanks mate.

OFF TOPIC:-

LONG LONG TIME AGO.

Can't remember what it was, something, "WHAT"

Something stupid *THINK* i had my test light on a wire, that i was soldering, can't rememer, but it was getting a supply from the diagnostic computer laptop on charge via the mains.

OFF TOPIC:-

Don't ask, i had in my back passage :toilet: a 24 volt laptop.

I had runing though a hole in the wall (pink floyd?) a 12 volt cable off some batteries on a charger upstairs (12 volt).

had down stairs a flat 12 volt battery and a good one, so like Justy22 i used the jump leads to 'help' the bad battery.

The laptop monitor was dud, so i used a CRT one, plugged in the 15 way, only the positive on the batterys and laptop powered up!

impossable but was drawing an earth via the mains! :party: rcd didn't go either.

cheap rework station, I had the glass in my heat gun shatter all over my bench before.

[faiscamix]

Can give another advice. Get a UPS for supply at least programmer/interface and pc. 2 months ago i was flashing an ecu on bench and a power surge ... Well you got. Lucky me i'm sort of backup maniac. I really don't need earth, my bech and myself we are isolated. I always believed more on double isolation than earth class (class1 vs class2 devices) lol. Learned on early age earth connections have more chances of going wrong because of oxidation. Another advice always use not conductive flux. And have an extra supply of pcc (i love that sh%$). Some problems also with conductive flux can apear. Leak current is our enemy lol

[Fallen]

Had this problem with my AOYUE 968, current running through machine.
I noticed it when I was soldering remote keys and the LED lit up.
When machine was off but still plugged in, you would get small shocks off the hot air gun, like you get off a tv aerial.

Did not try and track down problem, chucked it in the bin and got another brand.

Cost me a blown EIS and a IZF module, both expensive.

ON TOPIC:-

if the tip is low voltage less chance of this happening, but perhaps fit an RCD on each appliance - for those Emericans thats a GFI or someother shit wording
