On this particular subject (welding) I would imagine that Mr. Wightman probably knows more than most
I sometimes find it difficult to understand why people bother answering a post, talk rubbish and then at the end of it put "but I don't really know much about it". Where's the point ? It only serves to confuse the original poster.
You should only answer a post if and only if you know what you are talking about.
As for Paul not taking the forum seriously, well a little levity now and again is a good thing and Paul's positive input into the forum far outweighs his lighthearted (no pun intended ) posts. Poor Will
