25、; b) applicable standards and test methods for harmonic current emission, voltage fluctuations and flicker; c) immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges. This standard is applicable to equipment for arc
26、 welding and allied processes, including power sources and ancillary equipment, for example wire feeders, liquid cooling systems and arc striking and stabilizing devices. NOTE 1 Allied processes are, for example, plasma cutting and arc stud welding. NOTE 2 This standard does not specify basic safety
27、 requirements for arc welding equipment such as protection against electric shock, unsafe operation, insulation coordination and related dielectric tests. Arc welding equipment type tested in accordance with, and which has met the requirements of, this standard is considered to be in compliance for
28、all applications. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
