Product Description
1000Hz Medium Frequency Inverter Resistance Spot & Projection Welding Machine

Conventional Challenges vs. RX-HB65K Breakthroughs
- Severe Heat Deformation & Burn-Through: Excessive heat input warps thin sheets, warps workpieces, or burns through base materials.
- Heavy Spatter & Secondary Grinding: Intense spatter leaves burrs and bumps, requiring costly manual secondary polishing.
- High-Temperature Demagnetization: High temperatures cause permanent magnet rotors to demagnetize, reducing motor torque and increasing operating noise.
- Grid Shock & High Energy Costs: Single-phase AC power causes severe power fluctuations, low power factors, and excessive electricity bills.
- Minimal Heat-Affected Zone (HAZ): 1000Hz inverter controls heat with millisecond precision, delivering mark-free welds without coating burn or demagnetization.
- Substantial Energy Savings: 3-phase balanced input yields a power factor ≥ 0.95, reducing power consumption by 30% to 45%.
- Spatter-Free High Quality: Closed-loop constant voltage/current control guarantees uniform penetration depth and eliminates burrs.
- Zero Secondary Processing: Clean, smooth joint finishes bypass the need for grinding, drastically raising production line yield rates.
Core Technical Advantages
Standard power frequency (50Hz) has a 20ms supply cycle, whereas 1000Hz medium frequency operates at 1ms. Millisecond current control ensures precise projection melting and compaction while minimizing thermal radiation.
3-phase 380V balanced input prevents power grid fluctuations. With a power factor of ≥0.95, thermal efficiency is boosted significantly, achieving 30%-50% energy savings compared to traditional AC welders.
DC output avoids AC zero-crossing points. High synchronization between pressurization and energization completely stops spatter, providing smooth surface finishes and extending electrode life by over 50%.
Equipped with a Weinview touchscreen interface and Siemens PLC control system. Features reserved digital automation communication interfaces for seamless connection to robotic arms and automatic nut feeders.
Primary Applications & Typical Workpieces
1. Fasteners & Stampings
Automotive & industrial nuts (square, hex flange, round) projection welding onto sheet metal. Rapid, precise projection welding for lead wires and electronic bases.
2. Automotive Components
Body structures: Door lock brackets, seat rails, reinforcement plates on HSS/AHSS. Chassis & drivetrain: Clutch plates, brake lining brackets.
3. Home Appliances & Cabinets
Compressor mounting plates, switchgear cabinet fasteners, door hinges, and handles requiring low-mark or mark-free projection welding.
4. Dissimilar Metals & Specialty
Copper-to-steel, brass-to-steel, and stainless steel to mild steel welding. Silicon steel motor rotors, galvanized sheets, and wire mesh.
