Switching module for the power section of a welding control

Aufgabe der Erfindung ist es, eine kompakte und preiswerte Schweißsteuerung mit integriertem Leistungsteil zu realisieren. Die Erfindung löst die Aufgabe mittels eines Schaltmoduls für das Leistungsteil einer Schweißsteuerung mit Schaltmittel 2A, Kühlmittel 3A, Stromzuführungsmittel 1A und Isolationsmittel 8A, welches Isolationsmittel 8A derart angeordnet ist, dass es eine potenzialfreie Kühlmittelanordnung ermöglicht. Der Vorteil dieser Anordnung liegt darin, dass aufgrund der potenzialfreien Kühlmittelanordnung die Kühlmittelschläuche verkürzt werden können, so dass weniger Raumbedarf innerhalb der Steuerung erforderlich ist und somit auch die Steuerung als solche kleiner bauend realisiert werden kann. Auch die Anforderungen an die Kühlmittelschläuche werden aufgrund der erfindungsgemäßen Lösung geringer, da nun die Kühlmittel potenzialfrei ausgelegt sind und somit preiswertere Kühlschläuche oder sogar Kühlrohr, die unmittelbar mit den Kühlmitteln verbunden sind, verwendet werden können.
