Laser welding

Inverter arc welding power source, also known as arc welding inverter, is a new type of welding power source. This kind of power supply generally converts the three-phase power frequency (50Hz) AC network voltage into DC through rectification and filtering of the input rectifier, and then through the alternating switching action of high-power switching electronic components (thyristor SCR, transistor GTR, field effect transistor MOSFET or IGBT), inverts it into a medium frequency AC voltage of several kHz to dozens of kHz, and reduces it to dozens of V voltage suitable for welding through transformer, After that, it is rectified again and output a fairly stable DC welding current through reactance filtering.
