High Speed Automatic Medium Frequency CNC Multi Head Spot Welder Resistance

This High-Speed Automatic Medium Frequency CNC Multi-Head Spot Welder is a high-end welding workstation based on Medium Frequency Inverter (MFDC) technology and a CNC control system, engineered for the efficient, high-volume, and high-quality production of rebar mats and metal mesh products. Integrating advanced international structural concepts and customized for the Chinese market, it revolutionizes the operation mode of traditional semi-automated equipment. Its PLC-controlled fully automatic system drives multiple welding guns to work in coordination, capable of completing multiple weld spots in one cycle with automatic indexing, achieving high-speed automation from manual loading to finished welding. The equipment fundamentally addresses the disadvantage of traditional welders, such as high labor intensity, low productivity, excessive spatter, weak weld points, high failure rates, and low automation. Maintaining excellent performance only requires regular electrode replacement, making it a revolutionary solution for enhancing the capacity and quality of rebar mat welding production lines

• High-Speed Fully Automatic CNC Welding Process: The entire process is under fully automatic CNC control via a PLC. Multiple welding heads can be used to complete more spots per cycle, after which the worktable automatically indexes to the next row, repeating until all points are welded. Equipped with monitoring and alarms, it enables unmanned, high-speed continuous production with multiplied efficiency.

• Medium Frequency Energy-Saving & Direct Power Supply Technology: Utilizes a Medium Frequency Inverter (MFDC) welding power source, offering significant energy savings compared to line-frequency equipment, along with stable welding current and minimal spatter. The unique design of direct power supply from the transformer to the workpiece minimizes energy transmission loss. Combined with a maintenance regimen of regular electrode replacement, it ensures high performance while achieving energy efficiency and long-term operation.

• Intelligent Pneumatic Constant-Pressure System: The welder is equipped with a pneumatic electrode system featuring automatic preload force adjustment, delivering a relatively constant pre-pressure. Compared to spring preloading, it offers the distinct advantages of less electrode impact, reduced wear, and more secure weld points, further minimizing welding spatter and significantly extending electrode service life.

• Intelligent Integrated Management & Operation: Key electrical components are centrally controlled by the PLC, with intelligent management of operational status. The intuitive touchscreen interface makes parameter setting, process monitoring, and production management extremely simple and visual, greatly reducing operational complexity and the technical skill threshold
