<p>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.</p> |
