Last nightat the industry that I work for ,we found some liquid-tite that was bubbled and burnt like a fried egg. The wiring inside was also toast. The junior man,who is actually older than I, said it looked an arc welder had burned it up. I had often heard of this but never saw it. But it makes sense. We then looked at what was being welded and found it sitting on wood blocks on a steel deckplate,knowing it was insulated we then looked for the cause. The only way we found it could have happened was that the stinger, electrode holder, had the plastic insulator broken off the nose. Could this be possible? Both of us say so, but the General foreman says " no way!" Just wondered if some of the Industrial Maintenance guys have had similair occurences.
