Quick funny about sock hoods. During my apprenticeship at PSNS (WA State) a fellow apprentice and I were working inside smoke stack on a destroyer. He was working on a section that curved upward and was almost laying on his back up against the stack, while welding extreme vertical (almost overhead). Due to the cramped space, we had to wear sock hoods, and any who have worn them know that the don't want to stay straight, especially when you are looking up. To counteract, we would grab a bit of the hood in our teeth. Well, the electrode swung around in the stinger and hit the nice wet spot on the outside of the hood and boy DID HE GET A JOLT! No permanent damage, but the hootin' and hollerin' was unbelieveable.
