Anti-spatter compound in MIG welding serves primarily to

• A. increase arc stability
• B. reduce the build-up spatter on the welding nozzle
• C. improve penetration
• D. clean the base metal

Answer: (B)

Anti-spatter compound creates a thin film that prevents molten spatter from sticking to surfaces around the weld, especially the inside of the nozzle and near the tip. By repelling the spatters, it keeps the nozzle opening clear, which helps maintain proper shielding gas flow to the weld pool. That improved shielding is important for consistent weld quality, but the main practical effect you’re aiming for is less buildup on the nozzle itself, which reduces cleanup time and extends nozzle life. It isn’t primarily about changing arc stability, penetration, or cleaning the base metal.
