Abstract
A spot welding assembly is disclosed particularly adopted for precision welding of small components. The welding rod is carried at an outer side of the entire assembly in a clamp portion of an electrode slide block. The electrode slide block is in turn slidably carried in a feeder slide block which is in turn slidably carried by a carrier fixture. An adjustable spring bias is provided between the feed slide block and the electrode slide block.
