The present invention provides a welding mask including an expanding member. A glasses type shading film (400) is placed in a 2/3 spot of a face protecting film (300) and a solenoid (200) is placed at a corner of the shading film (400) to move an expanding member (100). Therefore, welding is generally performed by using only the shading film (400) but when a small object needs to be welded, the expanding member (100) is able to be moved onto the shading film (400). The purpose of the present invention is to solve inconvenience in welding by magnifying a small object.본 발명은 용접마스크에 있어서 얼굴보호막(300)의 2/3지점에 보면 안경형태의 차광필름(400)이 있으며 차광필름(400)의 모서리에는 솔레노이드(200)이 있어 확대부재(100)를 이동가능하게 형성되어 평상시 용접을 할 때에는 차광필름(400)만 사용하여 용접을 하며 작은 것을 용접할 시에는 확대부재(100)를 차광필름(400)위로 이동시켜 사용가능한 확대부재가 형성된 용접마스크를 제공한다.
