1. After using the infinite speed regulation of frequency converter, the whole range of speed regulation becomes wider, and its accuracy is very high, and the starting moment will also become larger.

2. Because the rollers are steel cores, the glue surface adopts groove-type planning and design, which effectively improves the service life, because the whole conflict force is relatively large, so it can bear more;

3. The production technology of welding positioner is relatively advanced. All the axes and holes are very good in parallelism and straightness, which reduces to the greatest extent. The lack of production accuracy leads to other phenomena such as workpiece movement.

4. The welding positioner can adjust the welding wheel according to the diameter of the welded workpiece, or adjust the bracket better at the viewpoint, so as to effectively meet the working requirements of different diameters and better enhance the driving of rotation.

5. On the base of the welding positioner, the combination type is adopted, so the whole rigidity is increased a lot, and the strength that can be endured is also increased.
