SPLATTER SHIELD
I frequently use my MIG welder to weld nuts onto broken or rounded off fasteners on engine components so I can remove them easily. When welding on a greasy old fastener you will likely get some weld splatter from the process and you do not want that splatter to stick to the surrounding areas of the component. I simply wrap the surrounding areas with tin foil so any welding splatter will be blocked.
