This series welding machines apply IGBT HF inverter technology.
Inputted line frequency 3-phase 380V are rectified by rectifier, inverted
into HF AC, reduced by HF transformer, rectified and filtered by HF
rectifier, then output DC volt or 50Hz AC square wave volt suitable for
welding by second invert. After this process, the welder’s dynamical
responsive speed has been great increasing, the size and weight of
welder’s transformer and reactor are reduced noticeable. Power source
enjoy sound anti-fluctuating ability due to excellent circuit loop control.
Power source can reach their potential as well as easy arc-start,
stable arc, pretty weld formation and continuous regulation of welding
current during external context changes(As to fluctuation in input power
supply and extended welding cables) due to reasonable control circuit
design .
