Grahod Keep your shirt on mate, was just clarifying (albeit clumsily) with Spanners,using as few words as possible, because he had used the term arc welding. The picture obviously has no value at all if it is taken after the beginning of the clean-up of the site. But if it is taken prior to the beginning of the clean-up, which I am assuming it was (otherwise why put it forward as evidence), it would mean a completely different scenario. And being a boilermaker, is there anything that tells you one way or the other? This is why I keep stressing that an open mind on the issue is important because this picture is either nothing, or something that one could hang an opinion on, and as yet I have no way of knowing.
