Moment of Stupidity...



Recently, I got tired of my soldering iron, the cable it too thick and short for easy use. I figured, having reasonable soldering skills, I would simple replace the original cable, with a different, longer, thinner one. So after opening up the iron, noticing that the original cable includes and earth wire (new cable does not, is this a problem?), I realised one major problem, I have only one soldering iron (this one) so have absolutely no way to solder the new cable. Good job I didn't remove the old one.

I think soldering irons need a ground, so it may be a problem.

As for the failed logic, good thing you caught that. Its sort of like selling your car so you can buy a new engine... for said car...

I would seriously put a 3 core flex on that iron. If any of the other 2 wires ever work loose and touch any metal inside, the earth wire is there so that the RCD at the fuse box gets tripped, and to give the current a quick path to earth instead of through your body.

I've been zapped before off the mains, hurt a bit, till the fuse box tripped, then I was plunged into darkness.

So, perhaps I'll look in wilko's for some flex and perhaps a 'backup' soldering iron.

I also know what it's like to have a good shakin' from the mains.

I also had a whack from a EHT output in the back of a TV, when I was younger. Th reflexes make all of your muscles tense up including the legs, which in turn causes the "thrown across the room" scenario. It is the body's natural way of attempting to remove you from the danger.

I was sort of confused when I was being woken up by paramedics a little while later, coz I don't actually remember the part where I shot backwards and knocked myself out on the wall.

One thing that I was taught in college... When working with high voltage (making adjustments), keep the hand that you are not using in one pocket. If you recieve a shock, the current will then go through one arm and across the shoulders, then down the other arm and exiting through the leg. It still flamin'-well hurts, but it's better than the current going through your heart, which in many cases means cardiac arrest.

Have fun but be safe.

one hand in the pocket, that's a bloody good tip. I would never have thought of that.
