This document summarizes the components and process of an auto tig welding machine. The machine is used to weld cylindrical sheet metal products along their length. It consists of a welding unit, side clamps, a holder, front clamps, a control unit, and a table. The welding process involves manually placing the cylindrical product in the holder, clamping it in place with the side and front clamps, running the welding unit along the product, then unclamping and removing the finished welded part.
