Experimental investigation of electric arc behavior during cutting of stainless steel

The present work is devoted to experimental investigation of electric arc behaviour during cutting of stainless steel. The goal of this work is to define influence of arc voltage fluctuations and anode attachment behaviour on the cutting performance. In most cases the anode attachment was verz luminous and was observed far from the main arc column close to the plate top. The cut material exhibited stronger surface roughness at the anode attachment location. The measured voltage traces showed a so-called restrike mode of oscillations of different frequencies and amplitudes.
