This part of GB/T 15579 specifies the safety and performance requirements for arc welding and cutting power supplies and auxiliary devices designed for use by non professionals and connected to single-phase public low-voltage power supply systems. Power supplies driven by mechanical equipment with an output power not exceeding 7.5kVA. Note 1: This type of equipment is usually used by non professionals in residential areas. This section is not applicable to the following arc welding and cutting power sources: with arc striking and stabilizing devices; Equipped with liquid cooling system; Equipped with air circuit device; Three phase input power supply: and power supply only for industrial and professional use. This section does not apply to arc welding and cutting power sources and auxiliary devices used in the following processes: (1) applications using mechanical guidance; Submerged arc welding- Plasma gouging: Plasma welding. The above situations are specified in other parts of GB/T 15579. Note 2: The requirements for power supplies, wire feeding devices, welding torches, and welding tongs for industrial and professional use can be found in GB/T 15579 1-2013 IEC 60974-5, IEC 60971-7, and IEC 60974-11. Note 3: This part does not include electromagnetic compatibility (EMC) requirements. This requirement can be found in the normative references of IEC 60974-10.2. The following documents are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
