The purpose of this International Standard is to give specific details or to complement ISO 5826, which deals with general specifications applicable to all transformers, relating to particular transformers within its field of application.
Unless otherwise specified, those requirements of ISO 5826 not modified by this International Standard are applicable.
This International Standard applies to transformers with two separate secondary windings for electric resistance welding machines for multi-spot welding as used in the automobile industry.
NOTE By agreement between the manufacturer and the user, this International Standard may also be applied to those transformers for multi-spot welding used in other industries or for other types of welding machines where possible. ISO 5826 is applicable in all cases.
