ISO 22829:2017 specifies additional requirements to those given in ISO 5826 for single-phase inverter transformers with connected rectifier for DC welding. This document applies to transformers, primarily used in welding guns, operating at 1 000 Hz with a rated input voltage of 500 V or more. The requirements of ISO 5826 shall be followed unless amended by this document.
