Versatile 3-in-1 Welding Modes
The RSN7-1600G is designed for extreme industrial loads, delivering a massive 1600A output to support studs up to Φ20mm through three specialized welding modes:
Mode 1: Ceramic Ferrule Protection Mode
Target: Large-scale shear studs (Φ16mm-Φ20mm).
Performance: Harnesses the full 1600A to create a massive molten pool. This is the standard for high-strength bridge decking and skyscraper foundations.
Mode 2: Advanced Gas Shielded Welding (20% CO₂ + 80% Argon)
Target: High-efficiency production of M3-M14 studs.
Performance: The CO₂ mixture stabilizes the high-energy arc, providing deep penetration on heavy-gauge steel without the need for ceramic ferrules, significantly speeding up large-scale assembly.
Mode 3: High-Speed Short Cycle Mode
Target: Rapid fastening of M3-M12 studs on thick structural components.
Performance: Leverages the 1600G’s immense power reserve to ensure instant, reliable ignition even on industrial-grade steel with significant surface oxidation.

-
1600A Peak Current Output: With a massive 60KW input capacity, the RSN7-1600G provides the highest energy density in its class. This ensures complete fusion for heavy-duty studs up to Φ20mm, meeting the most stringent structural integrity standards for massive steel-to-concrete connections.
-
Ultimate Duty Cycle & Heavy Chassis: Built into a 75kg reinforced industrial chassis, this model is optimized for maximum heat dissipation. It is designed to sustain high-frequency, maximum-current cycles on massive job sites, ensuring the machine stays cool while delivering constant power for long-shift operations.
-
Precision Control for Heavy Arc Loads: Equipped with a high-performance inverter control system, the 1600G allows for ultra-precise timing (up to 1800ms). This allows operators to manage the massive molten pool created at 1600A, ensuring a perfect, uniform weld collar even on the thickest base materials.
