Abstract

PURPOSE: To provide an inexpensive apparatus which enables detection of arc voltage without any change in connection required for change of welding power source by means of a level discriminator adapted to discriminate voltage level when an arc becomes stable between a torch and a base metal, with an arc voltage detecting section and a control unit connected through a filter device.
