Invented by the Russian engineer Nikolay Slavyanov, this welding set is the world's first semi-automatic machine for arc casting and welding. The casting metal is held between two metal electrodes with an electric arc between them. The arc melts the metal and the molten metal fills out the form. Later Slavyanov developed a fully automated mechanism that maintained the length of an electric arc constant to provide a more reliable method of welding.
