This is a new generation MIG Anti Spatter device which ones installed in the gas line of a welding robot or welding automated station, generates a protective anti spatter mist during welding. An electrostatic generator adds electrostatic charge to the fine droplets of the protective mist. The electrostatically charged protective mist passes through the welding gun continuously protects both the welding gun and welded details from welding spatters. In this way, an active shield is generated each time the welding is started. The device is autonomous and integrated into the welding equipment.
