METHOD FOR MAGNETIC CONTROL OF PLASMA ARC

摘要

A device for controlling a plasma arc is provided that includes a plurality of magnetic poles disposed around a distal end portion of a plasma arc torch. A plurality of electrical coils are wound around a proximal end portion of each of the plurality of magnetic poles, and a plurality of lead wires are connected to the plurality of electrical coils. A control system for controlling a current supplied to the plasma arc torch through the lead wires is also provided that changes at least one of a strength of a magnetic field produced by the magnetic poles, a polarity of the magnetic poles, and a movement of a magnetic force between the plurality of magnetic poles, such that a size and location of the plasma arc is controlled.
