1. Our welding positioner has employed frequency conversion speed regulation system to change its running speed. 2. The stepless speed regulation is adopted to make this positioner easy to control and cheap to maintenance. 3. Semicircular gears are equipped on both ends of the output shaft of the overturn device. 4. One end of the electricity-conducting device is connected with the swing set, and the other end has an electricity-conducting shaft. The electricity-conducting shaft is linked with the working table so that the welding current can be directly transmitted through the working table. 5. The box-shaped stander possesses high loading capacity. And it is made up of Q235-A steel which has undergone annealing and finish machining treatment, thus successfully avoiding the welding stress deformation.
