　　1、交(jiao)流(liu)(liu)電(dian)(dian)焊機(ji)(ji)干(gan)燥法操作前先將受潮減(jian)速(su)(su)電(dian)(dian)機(ji)(ji)繞(rao)組的個接(jie)線頭串(chuan)聯起來，機(ji)(ji)殼接(jie)地，這樣就可對三組繞(rao)組實現加熱(re)(re)干(gan)燥，為監視干(gan)燥過程中的電(dian)(dian)流(liu)(liu)變化，可串(chuan)入一(yi)只電(dian)(dian)流(liu)(liu)表，觀察其(qi)電(dian)(dian)流(liu)(liu)是(shi)否達到減(jian)速(su)(su)電(dian)(dian)機(ji)(ji)額定電(dian)(dian)流(liu)(liu)的。用交(jiao)流(liu)(liu)電(dian)(dian)焊機(ji)(ji)干(gan)燥直流(liu)(liu)減(jian)速(su)(su)電(dian)(dian)機(ji)(ji)不用對其(qi)進行(xing)拆檢(jian)，減(jian)小了工作量，同(tong)時在通電(dian)(dian)的情況下減(jian)速(su)(su)電(dian)(dian)機(ji)(ji)用其(qi)自身(shen)電(dian)(dian)阻發熱(re)(re)，使線圈(quan)均勻受熱(re)(re)，干(gan)燥效果比較好。
