Beschreibung
Zusammenfassung:	The invention relates to a method for cold treating rod electrodes, having a cooling phase during which the temperature of the electrode is reduced to a lower target temperature, a subsequent holding phase in which the electrode is substantially held at the target temperature, and a final heating phase, in which the electrode is brought to an upper target temperature. The use of rod electrodes treated using the method according to the invention leads to substantial improvements in the welding result compared to untreated rod electrodes, in particular a reduction of a welding spatter tendency, and allows a welder to more easily achieve a uniform welding seam with pronounced and uniform bead ripples.
