Free burning arcs at atmospheric pressure in sulphur hexafluoride (SF<sub>6</sub>) have been found to be extremely unstable. For potential gradient measurements to be carried out the requirements for wall-stabilization of the areas have been examined and compared with those for nitrogen. The characteristics for arcs in SF<sub>6</sub> and N<sub>2</sub> have been measured for currents up to 50 A by two different methods and these results have been used to determine the mean electrical conductivity as a function of are current
