Experience a brief tour of features designed to deliver dependable outcomes. In this video, we demonstrate the HJ4040 Heavy Duty Welding Manipulator in action, showing how it handles automatic welding of internal and external seams for boilers, pressure vessels, and pipes. You'll see its structural components—crossbeam, lifting system, column, and control system—and learn how to select the right manipulator based on boom expansion, load capacity, and workshop constraints. We also compare welding manipulators with positioners and explore compatible welding processes like SAW, MIG, and TIG.
