I am currently welding 7018 in elevator shafts. Wouldn't think it but there's a lot of welding in there for structural attachments. With pressing schedules and challenging work areas (like welding off extension ladders) I am constantly trying to find ways to get faster. I started taping my flashlight to my chipping hammer and got rid of my flashlight grab check weld move. Thought this was such a good idea I made a patent and built a impact resistant light source into the chipping hammer. You can check out the demos on YouTube key word slagenator. Let me know what you think.
