It used to prevent adhesion of unwanted spatter to the torch or substrate, generated in welding processes, especially in CO, TIG and MIG welding. A light spray over the work/jig etc. prevents most spatters sticking to the surface, and a simple wipe with a cloth or rub with a wire brush removes virtually all spatters. It is helpful in reducing unnecessary labour costs involved in removal of spatter and improving the finish of the welded article.
