The authors created a device with a gliding unipolar arc of the Jacob’s ladder type. This paper presents investigation results of the arc ascent dynamics. It was found that the arc motion is uniform on the major part of its way. The arc ascent has the convection nature due to the air heating by the plasma. Dependence of the arc ascent velocity on the apex angle between the electrodes is obtained. The dependence is decreasing.
