Solid State Hf Welder for ERW Welded Pipe Line

Solid State Hf Welder for ERW Welded Pipe Line. High Power Factor: Power factor reaches 0.92, eliminating the need for power compensation devices. Low Harmonic Pollution: Minimal harmonic generation, generally requiring no additional processing equipment. Stable Output Power: Output ripple is less than 0.2%, ensuring uniform welded pipe burrs. Fast Protection: Interlocking protection time is less than or equal to 10 microseconds for high reliability. High Power Efficiency: Improved machine efficiency due to reduced reactive power loss. Smooth Control: PWM modulation provides smooth and stable control with 75 microsecond response time. Wide Voltage Range: Input voltage allows a fluctuation range of plus or minus 20 percent. Reliable SCR Design: SCRs work in full conduction state but turn off quickly during faults for safety.
