Biodegradable Arc Guard forms thin, protective coating during first few moments of welding to prevent spatter from adhering to surfaces, nozzles, or tips. Remaining spatter can be knocked off or removed with wire brush. Spray works on carbon steel, SS, and aluminum and contains no chlorides, silicone, fluorocarbons, and flammable, hazardous, or odor-causing ingredients. Nozzle gel eliminates fumes and greasy drippings. Formula comes in 19 oz aerosol cans, quart bottles with pump sprayers, and gallon refills.
