Good question. I dont know the answer, but maybe heat preferes to rise. When you place the bar in the water it is vertical and the heat rises. ( Theory )
Maybe you are concentrating so much on the bar when its in the water, you forget you have a cigarette in your hand, and it burns you. Happens to me all the time. I also wish they had holes in welding masks so you could have a ciggy in your mouth while welding. Maybe I should patent that idea. |
