Stonecold is correct with the Pam spray preventing spatter. Most of the commercial anti spatter sprays are simlpy corn oil. The best plan is to optimize your weld parameters to prevent spatter, many of the new generation weld power supplies are light years ahead of the old motor/generator sets (don't laugh they are still out there) There are a couple of other little tricks that you can use. Spatter is cooling at a rate of about 1000 degrees per second so anything that you can do to prevent it from sticking while it is still molten will help. Can you re-position tooling? Another trick is to chrome plate tooling (not West Coast Chopper Quality) just send cleaned tooling to a plater and tell them you want a flash chrome no copper plating, no buffing, no nickel. The resulting shiny finish helps keep spatter from sticking. Last but not least a good preventative maintenance program for the tooling. Where your operator cleans tooling every shift, sprays anti spatter and prevents large build up.
good luck
