Just a quick image showing what may happen to your expensive mobile phone if you leave it in the top pocket of your shirt while welding overhead. You may also experience the smell of burning shirt, chest hair and flesh. And hear a lot of high pitched squealing. And have a sore head from miscalculating the height of the thing you were welding while escaping from all of the above. All of this happened to………… erm,…………………………… a friend of mine. Yes, that’s it, a friend of mine :-) Oh, and the phone still works fine. Ivor.
