Abstract

The presence of even harmonic components of current and, above all, the harmonic component with a frequency of 100 Hz is possible only if the electric circuit elements, the resistance of which depends on the direction of current. Such elements may be a contact of electrode with the melt and the electric arc AC. Change the relative content in electrode current harmonic component with a frequency of 100 Hz dependent from the penetration of the electrode in the melt and the degree of electric arc development.
