Product Description
Metal Resistance Spot & Projection Welding Machine
Engineered for high-accuracy spot and projection welding of nuts, bolts, and sheet metals. Driven by 1000Hz inverter technology to eliminate thermal deformation, spatter, and energy waste.
RX-HB45K Main Machine Overview
1. Traditional Welding Pain Points vs. MF Inverter Breakthrough
Traditional Welding Limitations
- Thermal Distortion & Burn-through: Excessive heat input causes warping, distortion, and substrate penetration on thin sheet metals.
- Heavy Spatter & Manual Grinding: Violent weld spatter generates burrs, requiring costly labor-intensive secondary polishing.
- High-Temperature Demagnetization: Heat buildup risks demagnetizing permanent magnet components and motor rotors, reducing torque.
- Grid Shock & Power Consumption: Single-phase AC welders induce severe power grid fluctuations, operating at low power factors and high power costs.
RX-HB45K Technological Solutions
- Minimal Heat-Affected Zone (HAZ): 1000Hz inverter technology with millisecond-level heating control ensures zero-trace welding without coating burn or demagnetization.
- Significant Energy Savings: Three-phase balanced load with a high power factor (≥0.95) cuts total energy consumption by 30% to 45%.
- Spatter-Free Quality: Constant voltage and constant current closed-loop control deliver uniform nugget penetration with zero spatter, eliminating post-weld grinding.
- Grid-Friendly Operation: Balanced power distribution protects local workshop electrical infrastructures from high-current spikes.
