Contact Energy Storage Stud Welding Machine
I. Product Overview:
A storage capacitor screw welding machine can weld screws, internal threaded screws, pins, and similar components to metal workpieces. During the welding process, the storage capacitor discharges through discharge at the tip of the component, with a discharge time of 0.001-0.003 seconds. No gas or ceramic ring protection is required, achieving a melt depth of about 0.1MM. This method is suitable for thin plates thicker than 0.4MM with no weld seams on the surface, no indentations, discoloration, or deformation on the back. It is ideal for applications requiring decorative surface effects, with a plate thickness to screw diameter ratio of 1:10.
II. Product Features:
Operated with an advanced international rotary control method and microcomputer control, the voltage adjustment precision reaches up to 1V. The microcomputer controls temperature detection, with the machine automatically shutting down for protection against overheating. Optimized for areas with significant voltage fluctuations, it passes EMC testing, high-voltage testing, prevents repeated welding, and implements temperature monitoring for the internal transformer section of the equipment. The machine automatically shuts down for protection when the internal temperature is too high.
Section 3: Application Scope:
Electrical cabinets, household appliances, sheet metal fabrication, signage, thermal fasteners, elevators, aluminum curtain walls, electrical systems, mechanical components, automotive industry, kitchen equipment, and the processing and manufacturing of metalwork.
