Scope

This Standard specifies the energy efficiency grades, minimum allowable
values of energy efficiency and test methods for arc welding machine and
resistance welding machine.
This Standard is applicable to the arc welding machine and resistance welding
machine that are designed for industrial and professional use, not exceeding
the voltage specified in GB/T 156.
The resistance welding machine to which this Standard applies specifically
refers to the resistance welding transformer which is finally installed with the
frame, the input circuit and the secondary circuit.
This Standard is not applicable to AC TIG arc welding machine, AC and DC TIG
arc welding machine, power frequency secondary rectification resistance
welding machine, seam welding machine, resistance butt welding machine,
flash butt welding machine, energy storage resistance welding machine,
inverter AC resistance welding machine, separately-sold resistance welding
transformer and mechanical equipment driven welding machine.
