A pair of vintage electrode holders/welding stingers, one marked with the brand Duro Engineering. Made in the United States, these units are designed for use in welding equipment and accessories, specifically for MIG, TIG, and stick welding. Unknown working condition, but a cool decor piece if not useable. Measures 9 inches long and generally 1 inch wide, except at plate in front of handle is 2 inches wide. DURO branded one seems to be in worse shape (see photos).
