Welders are employed to join metal parts by applying an electrical arc to the material. When the arc generates heat upon contact with the metal, it melts the material, facilitating a molecular bond with another piece of metal. As the molten metals cool, they fuse to create a robust, solid weld or connection. Various types of welding processes and machines exist, with the three most common being MIG, TIG, and stick welding. These processes can be executed either manually or with the assistance of a robotic arm. We sell used welders from such companies as Miller, Lincoln, and ESAB.
