FIELD: process engineering.
SUBSTANCE: invention relates to stone dressing and can be used in construction for cutting of reinforced concrete and hard nonmetallic construction materials. Disk electrode consists of two metal disks separated by two insulating gasket, "plus" being fed to one of said disks from power supply and "minus" to another one. Note here that thickness of said gasket makes 2.0-4.0 mm. Electric arc is initiated between two isolated disks with the help of high-frequency generator.
EFFECT: disk electrode to dress stone, concrete and nonmetals by indirect arc.
