A. Applying Scope

It’s used to weld rail. It adopts pressurized deburring mode. The press is rail bottom positioned to ensure the rail head straightness. The press is equipped with upsetting control valve to avoid delaying operation. Compared with the similar product, it features original conception, reasonable design and easy operation.
