無錫聯通焊接機械有限公司位於風光秀麗的太湖之濱- - - - - - -無錫，公司多年來專業生產焊接系統埋弧焊上的各種系列的lt焊劑回收機，焊條烘箱、焊條焊劑組合烘箱、操作機上的焊劑回收輸送一體機等等，是一家技術型和生產經營型相結合的高新技術企業；在同行業率先通過iso9001 ： 2000國際質量管理體系認證，是目前國內生產焊接機械輔機產品最具影響力及市場份額的工廠之一。 -
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。
