RSN7 DOUBLE-GUN SERIES
INVERTER DUAL-GUN DRAWN ARC STUD WELDING MACHINE(Ø3-38mm)
RSN7 DOUBLE-GUN SERIES
DOUBLE PRODUCTIVITY & UNMATCHED INDUSTRIAL RELIABILITYDual-Core Inverter Technology
Equipped with two independent inverter circuits and triggering mechanisms, allowing for independent operation of two welding guns and increasing production efficiency by 30%-50%.
Heavy-Duty Diameter Capacity
Supports welding stud diameters up to Φ38mm in single-gun mode, and up to Φ28mm when both guns are operating independently, meeting the most demanding large-scale steel structure requirements.
Intelligent Voltage Compensation
Features robust grid voltage compensation capability, maintaining stable welding output even during voltage fluctuations (AC 380V±15%) to ensure high-quality, consistent fusion.
Reliable Modular Design
The internal structure utilizes a compact, modular design. With the dual-core system, if one unit fails, the other can continue operating, ensuring uninterrupted construction workflow.
Dormant Cooling Protection
The fan operates in an intelligent dormant mode, running only when necessary to drastically reduce internal dust and metal particle intake, significantly extending the equipment's lifespan.
Versatile Industrial Application
Optimized for base plates ≥3mm, this series is engineered for heavy-duty industrial fastening tasks in bridges, high-rise buildings, shipyards, and power plant construction.
RSN7 Double Gun Inverter Series is the premier high-efficiency solution for large-scale industrial fabrication.

Quick Answer
RSN7 Double Gun Series FAQs
Find quick answers about our RSN7-2500-2, RSN7-3150-2, RSN7-4000-2, and RSN7-5000-2 inverter models. Learn about their double gun efficiency, welding range, and industrial protection features.
The main advantage is the dual-core inverter technology, which allows two welding guns to operate independently or simultaneously. This capability can increase construction speed by 30%–50% compared to using single-gun machines, significantly reducing labor hours on large projects.
The top-tier RSN7-5000-2 model supports welding stud diameters up to Φ38mm when using a single gun. When both guns are operating independently, the maximum capacity is Φ28mm per gun.
Because the machine features two independent inverter circuits, if one unit fails, the other gun can continue operating. This modular design ensures that your construction workflow remains uninterrupted while the faulty unit is serviced.
Yes, the RSN7 series is equipped with a robust grid voltage compensation function. It automatically stabilizes the welding parameters even when the input voltage drops significantly (supporting AC 380V±15%), ensuring consistent weld quality.
No, the machines are designed for user-friendly operation with intuitive controls. A standard welder can become proficient in operating the system within just one hour.
