CE Declaration of Conformity

The publication of the standard EN 5044522008 (product family standard to demonstrate compliance of equipment for resistance welding, arc welding and allied processes with the basic restrictions related to human exposure to electromagnetic fields) under the Low Voltage Directive LVD 2014/35/EU — published on the Official Gazette of the European Community, requires that each product, in order to be CE certified, has to satisfy the technical standards of the above described norm.

This means that today the CE marking requires a further certification. Telwin certifies that all its products are in compliance with the new CE marking as reported in the EMF Conformity Certificates.
