Abstract

One of relevant nonparametric parameter characterizing the welding power source is static output characteristic. The parameter is designated by loading the source with an adjustable resistor. However, in case pulsed gas metal arc welding (P-GMAW) power source, the measurement of relationship between the output voltage and the output current is dependent on several factors and ignoring them might lead to the incorrect evaluation of the varying slope in working point. The following work introduces some aspects of analysis programmable output characteristics of welding power source. To determine power supply volt/amp characteristic during background current time and pulse duration, special value of arc parameters have been set in synergic control system of welding machine. The analysis of registered images of interelectrode space with the use of high - speed photography has been presented. It has enabled the interpretation of the impact of change in pulse current value as change in the length of the electrode extension on metal transfer and arc stability of the arc.
