The present invention in performing a welding operation while wearing the antidust mask or helmet can be kept moderate the distance between the parallel keeping and welding surface between workers face the weld surface and the operator face to provide a welding surface. In A welding surface provided with a viewing window 4, which has a light-shielding plate curved facepiece 2 and the face piece 2 outer surface to the left and right direction, outside the lower the entire surface of the lower end position of the window 4 of tetrahedral 2 and characterized in that a stepped shape which protrudesFIELD 2【課題】防塵マスクやヘルメットを装着した状態で溶接作業を行う際に、溶接面と作業者顔面との平行を保ちかつ溶接面と作業者顔面との間隔を適度に保つことのできる溶接面を提供する。【解決手段】左右方向に湾曲した面体2と面体2の外面に遮光板を有する覗き窓4を設けた溶接面において、面体2の覗き窓4の下端位置より下側全面を外側に張り出した段付き形状としたことを特徴とする。【選択図】図2
