RSN7 SERIES
MANUAL LIFT INVERTER DRAWN ARC STUD WELDING MACHINE(Ø3-25mm)
RSN7 SERIES
ADVANCED INVERTER CONTROL FOR DEMANDING MANUAL WITHDRAWAL WELDINGIGBT Inverter Efficiency
Utilizes pure IGBT modular technology to ensure high reliability and a low failure rate. This advanced soft-switching design saves 30%–40% on electricity compared to traditional thyristor rectifiers.
Precision Manual Control
Features stepless adjustment of both welding current and time, allowing operators to fine-tune parameters for studs ranging from Φ3mm to Φ25mm. The digital display ensures real-time monitoring for flawless fusion.
Intelligent Voltage Compensation
Equipped with a grid voltage compensation function that automatically stabilizes the welding force even during significant voltage drops (AC 380V±15%). Ideal for job sites using generator power or long cables.
Dormant Cooling Mechanism
The intelligent fan operates in dormant mode, running only when necessary to reduce internal dust and metal particle intake. This specialized system extends the equipment's lifespan by up to three times.
IP23 All-Weather Protection
Designed for harsh onsite environments, the circuit boards feature specialized waterproofing, anti-corrosion, and dust-proof coatings. The IP23 rating makes it suitable for high-humidity tunnels and outdoor construction.
Versatile Industrial Application
Specifically optimized for base plates ≥3mm, this series supports not only stud welding but can also be customized for manual arc welding and carbon arc air gouging. It is the versatile workhorse for bridges, steel structures, and power plants.
RSN7 Manual Withdrawal Inverter Series is a robust solution for medium-to-heavy industrial fabrication. Specifically optimized for base plates ≥3mm, this series delivers exceptional stability when welding high-strength studs and anchors ranging from Φ3mm to Φ25mm. Whether for bridge construction, industrial plant installation, or high-rise steel frames, these machines handle stainless and alloy steels with precision, ensuring every weld meets the most rigorous structural engineering standards.

RSN7 Manual Withdrawal Series FAQs
Find quick answers about our RSN7-2000S and RSN7-2500S inverter models. Learn about their welding range, power efficiency, and industrial protection features.
The Manual Withdrawal series is optimized for heavy-duty welding on plates ≥3mm and larger studs (up to Φ25mm). In contrast, the Short Cycle series is designed for thinner plates (down to 1.5mm) and smaller stud diameters.
The RSN7-2500S is a powerful industrial workhorse that supports a wide welding range from Φ3mm to Φ25mm. It is specifically engineered to maintain arc stability even at the higher end of its diameter capacity.
This intelligent system allows the fan to run only when necessary, significantly reducing the amount of dust and metal particles sucked into the machine. This protection mechanism can extend the equipment’s lifespan by up to three times compared to standard cooling systems.
Yes. The RSN7 series features a grid voltage compensation function that automatically stabilizes welding parameters during voltage drops (AC 380V±15%). This ensures consistent, high-quality welds when using generators or operating at remote construction sites.
Not at all. The RSN7 series is designed for ease of use, featuring an intuitive digital display and stepless adjustment. A regular welder can typically learn the basic operation in 20 minutes and become proficient within just one hour.
