RSR-3150 Heavy-Duty CD Stud Welder (Φ3-12mm) | 198,000µF High Capacity

The RSR-3150 is the flagship high-capacity model in our Capacitor Discharge (CD) welding series, specifically designed for heavy-duty industrial applications requiring studs up to M12. Powering this powerhouse is a massive 198,000µF capacitor bank, ensuring maximum energy penetration for structural-grade welds on thick metal substrates. Engineered for 24/7 high-intensity production, the RSR-3150 delivers unrivaled strength and precision while maintaining the series’ hallmark “no-deformation” finish on stainless steel, aluminum, and carbon steel.

RSR-3150: The Ultimate Heavy-Duty Solution for Large-Diameter CD Stud Welding

The RSR-3150 is engineered for the most demanding metal fabrication challenges. Featuring an industry-leading 198,000µF electrolytic capacitor array, it provides the immense energy discharge necessary for the secure fusion of large M3 to M12 studs.

This flagship unit excels where standard welders fail, offering the perfect synergy of high-voltage power and rapid millisecond discharge (1-3ms). Even when welding larger diameter fasteners, the RSR-3150 prevents excessive heat transfer, protecting the integrity of the workpiece and eliminating backside markings or structural warping. It is the definitive choice for manufacturers in heavy infrastructure, marine engineering, and large-scale industrial enclosure sectors who refuse to compromise on bond strength or aesthetic excellence.

  • Unrivaled M12 Welding Capability: The RSR-3150 extends your operational range to its maximum, supporting stud diameters up to M12. This allows for structural-grade fastening in heavy industries, replacing traditional high-heat welding methods while maintaining speed and precision.

  • Massive 198,000µF Energy Bank: Equipped with our highest-capacity 198,000µF capacitor reservoir, this machine guarantees stable arc ignition and deep fusion. The extreme energy density is optimized for high-conductivity materials and thick-gauge aluminum, ensuring consistent, high-strength results.

  • Engineered for High-Intensity Production: Built for 24/7 industrial workflows, the RSR-3150 maintains an efficient welding frequency of 10–30 studs per minute. Its rapid-fire performance eliminates time-consuming post-weld grinding, significantly reducing the total cost of production.

  • Advanced Industrial Safety & Cooling: Designed for the toughest environments, it features an enhanced Intelligent Self-Inspection System and superior heat dissipation. It monitors voltage, current, and thermal levels in real-time, ensuring maximum uptime and a prolonged service life under heavy loads.

High-End Industrial Enclosures

As the series flagship, the RSR-3150 is designed for heavy-duty industrial control centers and premium server racks. With its massive 198,000µF capacity, it securely welds studs up to Φ12mm while ensuring zero heat deformation on 0.5-3mm thin plates. This guarantees a flawless, high-end exterior finish for the most demanding cabinet specifications.

Large-Scale Infrastructure HVAC

The ultimate choice for large-scale ventilation systems and industrial air-handling units. The RSR-3150’s 600W power enables high-frequency welding of thick insulation pins and structural anchors with unmatched stability. Its IP23 protection ensures reliable, continuous operation in rugged onsite environments for major infrastructure projects.

Heavy-Duty Marine & Signage

Engineered for maritime environments and large-scale outdoor signage that require maximum fastener durability. The RSR-3150 effortlessly handles Φ12mm studs on stainless steel and aluminum, providing superior joint strength. It prevents burn-through and discoloration, preserving the integrity of protective coatings on marine-grade materials.

Precision Automotive & Transit

A portable powerhouse for automotive assembly lines and transit vehicle fabrication. Whether welding aluminum body panels or steel structural components, the RSR-3150 delivers foolproof precision. Its high-speed pulse discharge ensures firm, clean welds on copper and alloys without damaging pre-finished or thin-walled surfaces.
