--- Cancellation of the narrow band limit relaxation in RF emissions (see 6.3.3 of the.2008 edition);

---According to the changes of IEC 61000-3-11.2000 and IEC 61000-3-12, the limits of harmonics and flicker are modified and the process is added

Figure (see 6.3.4);

--- Increased output current ripple requirements (see 6.3.5);

--- Modified the voltage sag requirements based on the changes in GB/T 17626.11 and GB/T 17626.34 (see 7.4);

--- Modify the informational appendix "Installation and Use" (see Appendix A);

--- Based on the changes in CISPR11.2009, the applicable limits were modified (see Appendix B);

--- Increasing the symbol of RF equipment category and use restrictions (see Appendix C).

The translation method used in this part is equivalent to the use of IEC 60974-10.2015 "Arc Welding Equipment Part 10.Electromagnetic Compatibility (EMC)
