1. method of using consumable electrode control welding procedure, wherein be adjusted and controlled welding procedure is implemented after lighting an electric arc by a source of welding current by a control device based on several different welding parameters, an at least one welding procedure stage with high-energy input that is caused by different materials transition and/or electric arc type and a welding procedure stage with low-yield input circulates to make up in welding process to be influenced or controls thermal balance, introduce the heat input of workpiece to be processed (16), it is characterized in that, with a cold metal transition stage (28) as the described welding procedure stage with low-yield input, welding wire during this stage (13) is carried up to contact workpiece to workpiece (16) direction, and after forming short circuit, carry welding wire in the other direction, thereby welding wire (13) conveying is got back to one on the position of workpiece (16) preset distance (30).
