Auguste de Méritens
Baron Auguste de Méritens was a French electrical engineer of the 19th century.
He was born in 1834.[1]
He is best known his work on magneto generators, particularly those used for arc lighting and lighthouses.[1] Similar magneto generators had been produced earlier by Nollet; de Méritens' innovation was to replace the rotor coils previously wound on individual bobbins, with a 'ring wound' armature.[2] These windings were wound on a segmented iron core, similar to a Gramme ring, so as to form a single continuous hoop. This gave a more even output current, which was advantageous for use with arc lamps.[3]
In 1881 he was awarded a French patent for the first arc welding process.[4] This used a carbon electrode to generate an arc to the workpiece. The process achieved relatively low temperatures and was not successful with steel. However it was widely used commercially, for welding lead plates to manufacture storage batteries. De Méritens produced this welding equipment with an enclosed hood and fume extraction pipe, to control the hazardous lead oxide fumes from the hot lead.[4]
He died in poverty at Pontoise in 1898.[1]
