RSN7 SERIES
INVERTER SINGLE-GUN DRAWN ARC STUD WELDING MACHINE (Φ3-32mm)
RSN7 SERIES
ENGINEERED FOR LARGE-SCALE STEEL STRUCTURES AND DEMANDING ONSITE CONDITIONSInverter Soft Switching Technology
Features advanced inverter soft switching technology that is small, lightweight, and environmentally friendly. Compared to traditional thyristor rectifier machines, it saves 30% - 40% in electricity consumption with efficient EMI design.
Modular IGBT Internal Structure
The internal structure is designed with a modular layout utilizing pure IGBT devices. This whole-machine integration ensures high reliability, a low failure rate, and can be easily maintained by ordinary electricians.
Intelligent Grid Voltage Compensation
Equipped with a unique voltage compensation function that automatically stabilizes welding parameters even during significant voltage drops. This makes it exceptionally suitable for power-shortage projects or sites using generator power.
Dormant Cooling & Dust Protection
The cooling fan operates in a dormant mode, activating only when necessary to save energy and reduce internal dust intake. This specialized mechanism extends the equipment's lifespan by up to three times longer.
IP23 Rated Industrial Protection
The circuit boards undergo specialized waterproofing, anti-corrosion, moisture-proof, and dust-proof treatments. With an IP23 protection level, it is engineered for high-humidity and harsh environments like tunnels and high-rise construction.
User-Friendly Precision Control
Features stepless adjustment of welding current and time with a digital display for real-time monitoring. The system is so intuitive that a regular welder can learn to operate it in 20 minutes and achieve proficiency in just one hour.
RSN7 Inverter Single Gun Series is the premier choice for heavy-duty projects like shipbuilding, power plants, and high-rise steel frames. Optimized for plates ≥ 3mm, it reliably welds high-strength shear studs up to Φ32mm. Even in harsh outdoor or high-humidity environments, these machines handle stainless steel and galvanized sheet with unmatched stability, ensuring every stud meets rigorous engineering standards with maximum fusion strength.
