PURPOSE: A mask for a welding operation is provided to support a beginner to implement a welding operation by confirming a part to be welded and precisely implementing the welding operation. CONSTITUTION: A camera(110) is arranged at the front side of a welding mask. A liquid crystal display(LCD) part(120) displays the front side of a welding monitoring window from the camera and confirms a part to be welded. A welding flame sensor(130) detects welding flame and stops the operation of the LCD part in order to form a light transmitting part which transmits the welding flame through the welding monitoring window.
