CNC Automatic Spot Welder Steel Bar Rebar Wire Mesh Fence Panel

This CNC Automatic Spot Welder for Steel Bar/Rebar Mesh and Fence Panels is a highly automated, professional system engineered for the large-scale welding of 6MM series steel bars, metal mesh, and fence panels. At its core, it utilizes 17 precisely arranged welding heads integrated with advanced CNC and PLC control systems. It achieves full automation through a unique "3-step, 6-spot" welding sequence. Custom-developed for the Chinese market and deeply integrating advanced international structural concepts, it completely overcomes a series of core drawbacks of traditional welders, such as high labor intensity, low efficiency, excessive spatter, weak weld points, high failure rates, and low automation. From bar loading to the completion of an entire rebar mesh or fence panel, the entire process of welding, indexing, and monitoring is automatically controlled by the system. Requiring only regular electrode replacement, it enables high-efficiency, high-quality, and highly consistent continuous production, making it the ideal solution for the intelligent manufacturing of rebar prefabricated components in the construction and infrastructure sectors

• High-Efficiency Fully Automatic Welding Process: The system integrates 17 welding heads and employs a unique "3-step, 6-spot" process. The welding sequence is under full automatic control via a PLC. After completing a row of spots, the worktable precisely indexes to the next position, cycling until all welding is finished. Equipped with monitoring and alarms throughout, it enables unmanned, high-speed production, delivering a multiple-fold increase in efficiency compared to traditional methods.

• Energy-Saving & Reliable Direct Power Supply System: Features a design where the welding transformer supplies power directly to the workpiece, resulting in a short energy path with minimal loss and significant energy-saving benefits. Maintenance is simple, as only regular replacement of the welding heads is required to maintain excellent long-term welding performance and stability.

• Advanced Intelligent Pneumatic Constant-Pressure Technology: Equipped with a pneumatic electrode system that automatically adjusts the preload force, delivering a relatively constant and precise pre-pressure. Compared to traditional spring loading, this system offers distinct advantages: less electrode impact, reduced wear, and more secure, reliable weld points. It also effectively minimizes welding spatter and significantly extends electrode service life.

• Intelligent Human-Machine Interface & Centralized Management: Key electrical components are under centralized intelligent control by a PLC, providing clear visibility into operational status. The intuitive touchscreen interface makes setting welding parameters, monitoring the production process, and managing the equipment extremely simple and visual, greatly reducing operational complexity and the required skill level for personnel
