Abstract

PURPOSE:To prevent entering of noise, by providing a TV camera, at least its section where image-taking light is converted to electrical signal, with a magnetic shield of ferromagnetic body. CONSTITUTION:Surrounding of a TV camera 5 is provided with a shield of mild steel 10. By doing so, when welding is executed by generating arc 2 between a welding torch 1 and a work 3 and the welding situation is taken as images by the TV camera 5 located near the arc 2 generating section to be shown on a monitor TV set 6 through a transmitter 14, optical fiber cable 15, and a receiver 16, even if current variation per unit hour of pulse current to be sent from a welding power source 4 through a welding table 9 to the welding torch 1 and the work 3 were to become higher than 100A/msec., because of magnetic shield action by a mild steel 10, magnetic conduction noise by pulse current can be prevented from entering the TV camera 5.
