An experimental investigation of the energy transfers to the anode, to the cathode and to the surroundings by radiation has been made for a direct current free arc in argon, for arc lengths from 0.63 to 2.54 cm and currents from 250 to 1100 A. A split anode arrangement enabled the deduction of the radial distribution of the energy flux and the current density and the maxima of these fluxes are considered in terms of their relation to arc length and to current. The convection heat transfer at the arc centerline is appraised more approximately in terms of a postulated voltage fall at the anode.
