An experimental investigation of the electric-field 
strength along the length of a cascade argon at a pressure lower than 
atmospheric pressure has been performed. The influence of different 
processes on the formation of the voltage-current and E-I characteristics 
of the arc was considered. It is shown that the processes of heat 
transfer are of primary importance; however, in the region of mixing 
of the cathode jet with the heated gas the Reynolds number has a marked 
influence. The generalized characteristics of the voltage across the 
arc, of the near-electrode voltage drop, and of the electric field 
strength averaged over the length are presented.
