Arc welding equipment is a set of tools used to join metal pieces together by melting them with an electric arc. The main components include a welding machine, which generates the electric arc, and electrodes, which provide the filler material needed for the weld. The equipment can be used for various metals, making it versatile for different projects. Safety gear is essential when using arc welding equipment. This includes welding helmets to protect the eyes from bright light and gloves to shield the hands from heat and sparks. Proper ventilation is also important to avoid inhaling harmful fumes produced during the welding process.
