Method for Compensating an Interfering Influence on a Welding Current from Another Welding Power Source

摘要

Method for compensating an interfering influence on a welding current, provided by a welding power source (4) for welding a workpiece (3), from another welding power source (4′), comprising the steps of:(a) providing (SA) a compensation voltage (UKomp), which is calculated on the basis of a welding current progression provided by the other welding power source (4′);(b) subtracting (SB) the compensation voltage (UKomp) from a measured voltage (UMess), measured by a voltage measurement unit (8) of the welding power source (4), so as to determine a corrected measured voltage (U′Mess); and(c) regulating (SC) the welding current generated by the welding power source (4) as a function of the corrected measured voltage (U′Mess).
