Radiation emission and absorption in arc plasmas are important energy transfer processes. Exact calculations, though possible in principle are usually impossible in practice because of the need to treat large number of spectral lines and also continuum radiation in the whole spectrum range. Recently, we have used approximate method of partial characteristics to evaluate radiation intensities, radiation fluxes and divergence of radiation fluxes for SF6 arc plasma with cylindrical symmetry. In this paper we have extended our calculations to argon arc plasmas for the plasma pressures of 0.1, 0.5 and 1.0 MPa. We have calculated coefficients of absorption for Ar plasmas at the temperatures from 300 to 35 000 K, and have used these coefficients to calculate partial characteristics. Both the continuum and line spectrum have been included in calculations. We have taken into account radiative photo-recombination and bremsstrahlung for continuous and over 500 spectral lines for discrete spectra respectively.
