★It is specially designed for SAW tractor. The whole body is made of alloyplate and greatly reducing the weight of machine. B1-2 type of recovery machine transfer the weight of the electric car to chassis electronic control box, it further reduces the weight of the car nose and stablize the travel of the tractor. 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.
