Abstract

The flexible face-engaging mask (34) covers the nose and mouth areas of a welder with a snug fit against the face so that an airtight seal is formed. The front face is fastened to a flange (45) riveted to the front of the face shield (13). The outside of the protective hood has a second flange (42) held by the same rivets (43). A rectangular opening (39) is provided in the face plate (13) which is covered by the replaceable filter element (40) and held within the flange (42) by means of the removable cover (38). A flutter valve (36) is supported by the flange (35) from the bottom portion of the face mask (34). The purpose of this valve is to permit easy exhaust of a welder's breath without the need for the exhaust to pass back through the filter element (40).
