Abstract
An automatic arc welding machine includes a work monitoring device comprising a light source for projecting a light to the workpiece and an image taking device which receives the light as reflected by the workpiece. The light source is so controlled in accordance with the operation of the image taking device that the average intensity of the projected light is increased when the image taking device is in operation. The arrangement is effective to increase the signal-to-noise ratio.
