Inverter Stud welding Machine   RSR-2500 Stud welding machine introduction This welding machineuse the capacitor discharge to weld the stud or corresponding screw fastly & firmly on the workpiece. It can improve the efficiency of production, decrease production, reduce the production cost (materials, labor, electricity), welding high strength and No deformation of workpiece and the characteristics of the welding position can be convenient, easy to operate, quick to learn. It can take the place of riveting or drilling etc fastening methods, welding time for only 3-6 ms, it can weld the stud on the thickness of only 0.3 mm sheet, does not cause deformation, discoloration or burn through, will not damage the paint or coating layer on the reverse of the workpieces. The equipment is widely used in rolling stock, automobile manufacturing, chemical industry, electronics industry, instruments and meters, kitchen appliances, metal ware, hardware and other industries, have higher economic benefit.
