What is ultra high frequency welding machine working principle & advantages?

  • KQH series ultra high frequency welding machine power supply adopts a series resonant circuit. After the inverter, the high frequency power supply is directly in series with resonant capacitor after output through high frequency transformer.
  • KQH Series high frequency welding tube power supply adopts high frequency chopper power regulation technology to replace the traditional silicon controlled power regulation technology to achieve microsecond level control, which greatly realizes the rapid adjustment and stability of power output in the process of welding tube. The output ripple is very small and the oscillation current is stable to ensure the smoothness and straightness of the weld.
  • ZHENGZHOU KETCHAN KQH series ultra high frequency welding machine power supply adopts MOSFET device to do current control, adopts imported high power resonant capacitor, adopts our company’s unique soft-switch inverter technology, obtains stable resonance frequency, effectively improves the quality of products, and realizes the stability of the welded pipe process;
  • High efficiency and energy saving: KQH series ultrahigh-frequency tube welding power supply adopts high-power soft switching technology from input to output to minimize power loss and achieve extremely high electrical efficiency, and has an extremely high power factor in the full power range, effectively saving energy. Compared with the traditional electronic tube high-frequency power supply, it can save electricity by 30 ~ 40%.
  • Safety: there is no high frequency voltage of ten thousand volts in the equipment, which can effectively avoid radiation, interference, discharge, and ignition.
  • Small size, integration, saving space. The ultra high frequency welding machine does not need a step-down transformer, does not need a thyristor to adjust the function of the power frequency inductor, small integrated structure for installation, maintenance, transportation, and debugging have brought great convenience. 
  • KQH series ultra high frequency welding machine power supply of our company designed a full range of protection functions such as overcurrent protection, underwater protection, overheat protection, overvoltage protection, short circuit protection, lack of phase protection, greatly increase the equipment reliability and maintenance convenience.
  • KQH series ultra high frequency welding machine power supply has a variety of internal display functions such as frequency display, current display, voltage display, and power display, so that the working condition of the equipment is intuitive, for the design of induction coil and power matching selection more guiding role;
