ABSTRACT:
The trajectory and speed of a turning electric arc in a device for cutting, eroding, welding or depositing material are controlled by varying the voltage and frequency of a polyphase current supplied to pole pieces disposed about the arc. The arc may be formed into a practically continuous bell-shaped or cylindrical sheet, thereby increasing the arc power.
