  • Method for measuring the extent of shielding function of an arc atmosphere and an arc welding machine including a nitrogen oxide measuring device measuring the extent of shielding function
    Patent number: 4095080
    Abstract: The extent of shielding function of an arc atmosphere is measured by the concentration of nitrogen oxide in the arc atmosphere. The concentration of nitrogen oxide in the arc atmosphere is measured by a nitrogen oxide measuring device. The measured value is indicated by an indicator. When the measured value exceeds a predetermined reference value, an alarm device is operated or a welding operation is stopped. Either a supply of shielding gas which forms an arc atmosphere is controlled, or a flow of fume is controlled through a fume exhaust device, as a function of the measured value.
