SD-1800A type mold cold welding machine is a technology that uses a large current pulse to flow through the joint surface of the workpiece and the repair material, which instantly produces a temperature of over a thousand degrees to make it rapidly weld. It is suitable for repairing the surface of workpieces and molds with small defects (such as machining dimensions, over-tolerance, impact damage, argon welding deficiency, casting defects and accumulated wear).
