Fig. 2: Block diagram of principle
This series welding machines apply IGBT soft switch inverter technology.
3- phase input volt are rectified by rectifier, inverted into HF AC, reduced
by HF transformer, rectified and filtered by HF rectifier, then output DC
power suitable for welding. After this process, the welder’s dynamically
responsive speed has been greatly increased, so the
welder size and weight
are reduced noticeably. Power source enjoys good anti-fluctuating ability
and high-quality performance
