Never meant to imply you were stupid, just having a little fun with you.:-)
In order to cause enough shock in a joint of pipe to rattle the electrons around you would need to drop it from a 10 story building. Think about how magnetism works and I think you will see my point.
I have welded miles of pipe pulled from out of the ground with enough magnetic attraction to pull a Ball Peen hammer out of your hand.
Like I said all you need to do is throw a few wraps with the ground lead around the magnetic area and go to welding.
