GB 28736-2019 Minimum allowable values of energy efficiency and energy efficiency grades for welding machines
Abstract
This standard specifies the energy efficiency grades, energy efficiency limits, and test methods for arc welding machines and resistance welding machines.
This standard applies to arc welding machines and resistance welding machines designed for industrial and professional use, powered by electricity at a voltage not exceeding that specified in GB/T 156.
The resistance welding machines covered by this standard specifically refer to resistance welding transformers that are ultimately installed with frames, input circuits, and secondary circuits.
This standard does not apply to AC TIG arc welding machines, AC/DC dual-use TIG arc welding machines, industrial frequency secondary rectifier resistance welding machines, seam welding machines, resistance spot welding machines, flash welding machines, energy storage resistance welding machines, inverter AC resistance welding machines, resistance welding transformers sold separately, and mechanically driven welding machines.
