[QUOTE="apprentice87, post: 554446, member: 13534"] Ok, a bit of a question from me!! How is it that the secondary windings of a welder are separate from the primary ones, AND, apart from the welders designed by "experts" many years ago, the secondary is not connected to the case of the machine in any way. [It is not earthed] So, the secondary is entirely isolated from both the primary and earth too.. BUT, you kneel on damp earth, and say scratch your face with the end of the rod, and you will get a shock alright!! [Guess how i know... john.. [/QUOTE]
