The variable polarity power supply circuit uses two stages full - bridge inverter, the former inverter is regarded as a constant - current source with fast dynamic response, and supplys energy for the second one, and the latter one is to produce variable polarity current excellently, and low - frequency pulse current by variable polarity power supply is used to reduce input energy and control the shape of weld bead while welding. a series of high - frequency pulse current is superposed on direct - current - electrode - negative ( dcen ) current through the high - frequency pulse power supply, which is used to compress the arc and improve process of crystallization
其中變極性電源採用二次全橋逆變結構，一次逆變提供快速的響應速率並給二次逆變提供能量，二次逆變提供良好的變極性性能，使輸出能量最優化，並用其低頻電流特性減小電弧線能量，控制焊縫成形;高頻脈沖電源提供的高頻電流疊加在反極性電流dcen上，利用電流的高頻特性壓縮電弧，改善焊縫金屬結晶過程。Non - destructive testing of steel tubes - part 10 : radiographic testing of the weld seam of automatic fusion arc welded steel tubes for the detection of imperfections
