The welding positioner controls of turning motor,overturning part and electric control system.It achieves welding and assembly angles by working table turning and overturning.working table are controlled by frequency converter,so that it can get a best welding speed.As the reson of eccentric and gravity distance,you should choose a bigger type positioner for long length and large weight workpiece,sometimes standard positioner can not suitable for any shape of workpiece,we designed many different types of positioners,Such as tilting type,lift type,head and tail stock rotary type,turn table type,double rotary type,etc.,it also can be integrated controlled with welding manipulator or robot,We can customized design and manufacture according to different types of workpiece of clients.
