Welding mask refers to the tool used to protect the safety of operators in welding and cutting operations. Commonly known as welding cap. The mask is a kind of shielding tool to prevent the damage of t part and neck caused by arc spatter, arc light and radiation light during welding. It has two types: hand-held and helmet type.
