Resistance welding equipment - Electromagnetic compatibility (EMC) requirements1 Scope This part of IEC 62135 is applicable to equipment for resistance welding and allied processes which are connected to mains supplies with rated voltages up to 1 000 V a. c. r. m. s. This standard does not define safety requirements. Resistance welding equipment type tested in accordance with, and which has met the requirements of, this standard, is deemed to be in compliance for all applications. The frequency range covered is from 0 Hz to 400
