★It is specially designed for SAW tractor. The whole body is made of alloyplate and greatly reducing the weight of machine. The welding tractor. can welding while recycling & feeding. At the same time it can greatly reduce the manual labor. ★Through observation window, we can see the application situation of flux. When the flux is insufficient we can add flux from the flux port.
★Heat insulation function can be added upon requests. It can realize automatic temperature 120 ℃ and prevent the water which is generated from cooling flux and then ensure the welding quality.
