Technical Activities

The Section currently maintains the EW 1 standard for power sources, the EW 3 standard for wire feeders, the EW 4 standard for graphic symbols, and the EW 6 standard for precautionary labels. The Section also supports the operation of the U.S. Technical Advisory Group to IEC TC 26 which develops and maintains safety, performance, and electromagnetic compatibility standards for the following products: power sources for arc processes, power sources for resistance welding processes, cooling systems, arc striking and stabilizing devices, wire feeders, torches, gas consoles, electrode holders, and coupling devices. In addition, the Section supports the operation of the ANSI Accredited Standards Committee W1 which is currently embarking on the U.S. adoption of many of the IEC TC 26 developed standards.

Government Affairs

Through NEMA, the section develops industry positions on legislative and regulatory initiatives that may affect member products, markets, and customers. NEMA's work has resulted in contributions to public policy development and in promoting competitiveness, technological progress, and public safety. On the Government Affairs homepage members can search for and e-mail federal representatives to convey opinions regarding energy policy or other issues related to the electroindustry.

NEMA Government Affairs provides specific services to its members and information in the areas of Environment, Health & Safety; Energy; and International Trade & Commerce.

Market Economics

Through NEMA, member companies are able to develop and implement tailored, industry-specific market and statistical programs that benefit participating companies. Reports may include:

  • Product orders and sales
  • Market forecasting
  • Shipments by trading areas
  • Channels of distribution
