Funny story, maybe not for those involved. During the time I worked in the industrial engineering department of a large steel fabricator we began switching parts of the structural welding area to wire feed machines from stick welding. The weldors hated it. When they were stick welding they could take a drag on their cigarette or light a new one every time they lifted their helmet to change the rod. The continuous feed wire welders didn't give them that break. There were a couple of guys managed to smoke with their helmets down. I never did figure out how they accomplished that.
