Abstract: PURPOSE:To realize a stable and accurate TIG arc length control by stopping an arc length control just after starting the welding and temporarily stopping the welding by sending a warning signal while under welding, when the arc voltage becomes out of the range of the upper and lower limit reference voltages. CONSTITUTION:The arc voltage inputted from a torch 6 and the upper and lower limit values inputted from an arc voltage upper and lower limit setter 26 are compared by an abnormal arc voltage detector 29 by setting the upper and lower limit values for the reference voltage of an arc voltage setter 18 on the setter 26.
