My job is running short arc on a few robots and spatter is an issue getting on threaded bosses. We put a copper cap on top but spatter clings to the base and sometimes pops under the cap onto the bottom threads. We use Chemtool spatter spray but it does not seem to make any difference on resisting spatter sticking or making removal easier. I am needing the operator to try to change settings to reduce the spatter but does anyone have a good spatter spray to protect tubes and bosses when welding? Needing something in a job shop size operation.
