The difference between modern arc welding power supply and traditional arc welding power supply is briefly described.
Different current modes have different energy utilization rates.
1, the current mode is different: the traditional arc welding power supply directly outputs the AC power supply after rectification, while the modern arc welding power supply converts the input AC power supply into DC power supply, and realizes the stable control of the arc by controlling the waveforms of current and voltage.
2. Different energy utilization ratio: The traditional arc welding power supply has low energy utilization ratio, while the modern arc welding power supply has realized high-efficiency energy conversion by adopting advanced power electronic devices and control technology.
