In recent years, the production of metal powder has become increasingly large-scale, and the requirements for the quality of the obtained powder are becoming stricter (fraction, sphericity, purity, flowability) - this is due not only to the increased demand for powder from standard industries of metallurgy, but also because the emergence and spread of additive technologies. In this article, a new method will be described for the production of metal powders, including titanium ones, the experimental results are given, namely, the value of currents, voltages and gas consumption in various operating modes. As a result of the experiments, a nominal operating mode was identified for one of the installation modules. Electric circuits and calculation model are given.
