Two Heads Multi Point Projection Resistance Welder Capacitor Discharge Energy Storage Spot Welding

This Capacitor Discharge Multi-Point Resistance Welder is a precision welding solution based on Capacitor Discharge (CD) technology, engineered for high-efficiency, high-quality synchronous multi-point projection and spot welding. Its core advantage lies in its dual welding head configuration, enabling the completion of two weld spots simultaneously in a single work cycle. It excels at welding non-ferrous metals like copper, silver, and nickel alloys, as well as dissimilar metal combinations, while also delivering excellent performance on common ferrous metals such as carbon steel and stainless steel. The technology utilizes high-density, short-duration energy released instantaneously from capacitors to achieve high-quality joints with minimal heat-affected zones. It is the ideal choice for industries with stringent demands on weld strength, appearance, and efficiency, including automotive manufacturing (for high-strength steel, hot-stamped steel, nut projection welding), hardware, appliances, precision electronics, and eyewear fabrication

• High-Rigidity Shock-Resistant Frame & Dual-Head Structure: Features a robust single-sided C-frame with high rigidity, internally designed with multiple reinforcing ribs to ensure minimal deformation when welding high-strength materials. The two independent welding heads support synchronous or independently programmed operation, providing an efficient hardware foundation for multi-point, array-type projection/spot welding, significantly boosting production capacity.

• Capacitor Instantaneous Discharge & Precision Force Control: At its core is a capacitor energy storage and discharge system, offering an extremely short (millisecond-level) weld time with concentrated, precisely controllable heat input. Equipped with an electro-pneumatic proportional valve for high-precision, stepless linear adjustment of welding force, ensuring optimal process matching of energy and pressure.

• Precision Guidance & Efficient Water-Cooled Power Source: The upper electrode moves vertically on high-precision linear guides with high repeatability positioning accuracy, guaranteeing absolute precision of weld spot location. The main circuit utilizes a fully water-cooled resistance welding transformer and rectifier for strong, stable output. Coupled with an efficient cooling system, it supports prolonged, continuous high-duty-cycle operation.

• Comprehensive Safety Protection & Convenient Operation: The secondary circuit employs a design with an insulated pressure cylinder base and upper arm for safety and reliability. Integrated air and water pressure monitoring switches with audible/visual alarms effectively prevent welding during coolant or power medium abnormalities. Standard foot switch control is ergonomic, enabling efficient and straightforward operation.

• Broad Material & Industry Adaptability: Thanks to its unique energy release characteristics, the equipment offers exceptional material compatibility, handling everything from highly conductive non-ferrous metals to high-strength steels. It finds wide application across dozens of industries including automotive, aerospace, appliances, and microelectronics, serving as a versatile platform for achieving high-quality, highly consistent welds
