In a somewhat timely - or untimely - manner, in between this post and the last one, I was using my PC to cut out a 210 x 250 x 8 mm plate and after cutting two sides I had to reposition the plate. Went to strike an arc and instead got a slight jolt. turns out I forgot to reattach the earth to the workpiece. It was much less than a spark plug sort of jolt but it was definitely there.

Your "tingle" sounds very much less than a full blown passage of electricity through the body. I really hate electric shocks so take great precautions with the likes of removing spark plug leads while the motor is running and fiddling with electric fences. However, those are primarily voltage issues while it is the current that is normally the life threatening component and that danger increases with the rise in amps: The exception being that teeny milli amperage that interferes with the heart rhythm! I think it causes ventricular fibrillation.
Nevertheless, it is all a little disturbing.

I do my own minor electrical work, I do not touch fuse boxes or anything...
But an electrician is a long way away from here and costs a fortune just in travel costs... Plus I have seen plenty of dodgy work electricians do... At the moment I have discovered in the main meter box I have two sheds, one has a fifty amp breaker, the other a 35 amp.... Except they have been wired incorrectly, the shed that should have the fifty amp breaker is obviously on the 35 amp one as it is the one that clicks down sometimes when I run the welder...
I had three phase sockets incorrectly wired, some motors ran backwards on one plug, forward on the other.
In the house we had a power wire on a freshly installed light fitting not insulated and it contacted the light frame and blew the fuse..
