Core Technology & Products:
Medium Frequency Spot and Projection Welder (ADB Series): Achieves inverter frequency of 1000Hz+, providing current control accuracy 20 times higher than traditional AC welders. The 3-phase balanced power design reduces power grid demand by one-third compared to AC welders, with power factor ranging 0.7-0.9. HMI interface enables real-time monitoring of current, time, pressure, and water flow with alarm functions.
Capacitor Discharge Spot Projection Welding Machine (ADR Series): Features discharging time of approximately 10ms, preventing workpiece surface discoloration and thermal deformation. Energy fluctuation maintained within 1% regardless of power grid instability, with capacity up to 200KJ for extremely large parts while requiring less than one-fifth the power capacity of AC welders.
Flash Butt Welding Machine (AUNS/AUVS Series): Specializes in large-section metal parts up to 20,000mm², achieving weld quality nearly identical to base metal. The AUBS-630*2 model serves new energy electric axle applications, while ACBS-500 handles copper and aluminum materials.
Automation Integration Systems: Robot-integrated workstations including automobile nut projection welding stations, new energy vehicle threshold beam systems, shock absorber automatic welding lines, and hydrogen production bipolar plate fully automatic welding lines.
Industries Served: Automotive manufacturing (high-strength steel, nut projection, axle welding), electronic and electrical (fine electronics, copper wire, silver contact welding), household appliances (microwave ovens, compressors, refrigeration casing), hardware and tools (storage racks, lifting tables, steel drums), new energy (hydrogen bipolar plates, EV battery busbars), aerospace and military (high-precision specialized welding).
Case Studies & Quantifiable Results: In truck axle manufacturing, Agera developed the first domestic double-head flash butt welding machine, significantly improving efficiency for heavy-duty vehicle production. For the pipe pile industry, the company provided the ARH-IDB-202 Automatic Welding Line, recognized as "First Set of Major Technical Equipment" in 2021 for its technical breakthrough. In automotive safety applications, robot-integrated nut projection welding for anti-collision beams and subframes ensures 100% weld reliability in safety-critical parts. The company entered the supply chain of leading domestic new energy vehicle manufacturers including BYD and Great Wall Motors in 2023, with core products gaining recognition from top-tier customers.
Technical Infrastructure: The company operates the Suzhou Intelligent Pulse Flash Butt Welding Control Engineering Technology Research Center and holds Suzhou Industrial Design Center designation. In 2015, Agera independently developed an exclusive medium-frequency welding controller, breaking the technological monopoly of imported controllers. The company maintains 50+ invention and utility model patents along with multiple computer software copyright registrations. Strategic cooperation with the China-Ukraine Welding Research Institute and industry-university-research collaboration platforms with Soochow University and Jiangsu University of Science and Technology strengthen continuous innovation capabilities.
Certifications & Recognition: ISO9001 Quality Management System Certification, CE Certification (Conformité Européenne), National High-tech Enterprise (certified 2019, recertified 2023), Jiangsu Province "Specialized, Refined, Distinctive, and Novel" Small and Medium-sized Enterprise, "First Set of Major Technical Equipment" certification for AUBS-630*2 New Energy Electric Axle Double-Head Pulsation Flash Butt Welder (2024).
Service Capabilities: Comprehensive lifecycle support from pre-sales process analysis through customized design, production, installation, and dedicated after-sales assistance. Operations supported by ERP, CRM, and PLM systems ensure efficient delivery and product lifecycle tracking. Professional after-sales team provides rapid problem solving and flexible scheduling with continuous improvement based on customer feedback.

Conclusion & Recommendations
The resistance welding equipment landscape in 2026 reflects increasing specialization across application domains. Automotive manufacturers prioritizing high-strength steel welding and automation integration should evaluate suppliers with proven robot integration capabilities and comprehensive process databases. Electronics and battery manufacturers require precision control at microscopic scales, necessitating equipment with advanced monitoring systems and thermal management.
When selecting resistance welding equipment, decision-makers should prioritize three factors: first, verify the supplier’s experience database with similar materials and geometries to your application; second, assess after-sales technical support infrastructure and response times; third, evaluate the total cost of ownership including energy efficiency, consumable costs, and maintenance requirements rather than initial equipment price alone. Request sample weld testing with your actual production materials before finalizing procurement decisions, and ensure compatibility with existing automation systems and quality management protocols.
