FIELD: metal working. SUBSTANCE: arresting channel is provided along a cutting line. The channel receives an uninsulated conductor mounted with a spaced relation with respect to a metal to be cut. The space of the channel is filled with an electrolyte, the conductor is connected to the negative terminal of a power source, whereas the metal is connected to the positive one. The cutting is carried out many times in two stages. At the first stage the electrolyte is still. At the second stage the electrolyte is pumped in the arresting channel. EFFECT: simplified method. 4 dwg
