Electrodes vapour material transport characteristics in the free-burning electric arc and formation of its pressure gradients are investigated. It is shown that adequate defining of gas-dynamic characteristic of electric arc plasma demands successive account of the thermal conductivity processes in the channel arc region. The roles of the gas-dynamic and diffusion processes as transfer mechanisms of electrodes erosion products are compared. The method using distant stabilized wall to study the transfer processes out of channel proposed.
