Abstract

An arc hood includes a housing having a first chamber with two ends, a top and a bottom having an opening, and a smaller second chamber disposed on the top of the first chamber. The smaller second chamber includes two ends, a top and a bottom. Each of the ends of the second chamber have an opening, are disposed above the top of the first chamber, and are recessed from a corresponding one of the ends of the first chamber. The chambers define a passageway between the opening of the bottom of the first chamber and the openings of the ends of the second chamber. One or more baffles are within the housing and are disposed between the opening of the bottom of the first chamber and the openings of the ends of the second chamber. A seal is disposed about the opening of the bottom of the first chamber.
