It is specially designed for SAW tractor. The whole body is made ofalloy plate and greatly reducing the weight of machine. B1-2 type of recoverymachine transfer the weight of the electric car to chassis electronic controlbox, it further reduces the weight of the car nose and stablize the travel ofthe tractor. The welding tractor can welding while recycling & feeding. Atthe same time it can greatly reduce the manual labor. Through observationwindow, we can see the application situation of flux. When the flux isinsufficient we can add flux from the flux port.

Heat insulation function can be added upon requests. It can realizeautomatic temperature 120 degree centigrade and prevent the water which is generated from cooling flux and thenensure the welding quality.
