This International Standard specifies the information to be given in equipment specifications and the test methods to be used for measuring those characteristics. Not all requirements apply to all types of equipment. The following types of power sources are included: - single phase with alternating welding current; - single phase with rectified welding current by rectification of the output of the welding transformer; - single phase with inverter welding transformer; - three phase with rectified welding current by rectification of the output of the welding transformer; - three phase with a current rectification in the input of the welding transformer (sometimes called frequency convertor); - three phase with inverter welding transformers. This International Standard does not apply to welding transformers that are separate from the equipment.
