A welding manipulator is a mechanical device used to position and support a welding torch or gun in a variety of positions and angles. It is typically used in heavy manufacturing and fabrication industries to automate the welding process and increase productivity. The manipulator typically consists of a series of interconnected joints, such as hinges or actuators, that allow it to move and position the welding torch or gun with a high degree of precision and repeatability. The manipulator may be mounted on a fixed base or mounted on a mobile platform such as a gantry or robotic arm. It can be controlled manually or through a computer numerical control (CNC) system.
