Arc Welding


Overview

Arc welding is a process that uses a power supply (i.e., an electrode) to create an electric arc that melts and fuses metals at the point of contact.

Arc-welding power resources and wire products include

  • Automatic and manual devices to feed continuous electrode wire
  • Electrical equipment and supplies for engine-driven, utility-powered, and plasma welding, and associated supplies and attachments
  • Resistance welding equipment supplies and controls
  • MIG (metal inert gas) gun, plasma welding, cutting torches, and stick electrode holders

Through NEMA, Members advocate for industry-backed environmental, health, and safety regulations.
