摘要：1. Apparatus for representing the influence of welding parameters on thecurrent voltage working point during arc welding, wherein the current and voltage valuesare transferable to a large-scale analog indicator forming a co-ordinate system, thecurrent and voltage values being represented as a point in the co-ordinate system independence upon the chosen welding parameter, and measuring devices being providedfor the values of the remaining welding parameters, characterised in that the measuringdevices are connected to large-scale digital indicators (5-9) and that the currentvoltageoperating ranges (3, 4), which are divided into a spray-arc range (3) and a short-arc range(4), are represented on the large-scale analog indicator (1), on charts, diagrams, or byprojection of the large-scale indicator.
