一，的正確使用方法(fa)如下：

1、焊接(jie)時(shi)應先調節電池電極(ji)(ji)桿的位(wei)置，使電極(ji)(ji)剛(gang)好(hao)壓到焊件時(shi)，電極(ji)(ji)臂保(bao)持互相平行(xing)。

2、電流調(diao)節開關級數的選(xuan)擇可(ke)按焊(han)件厚度(du)與材質而選(xuan)定。通電后電源指示燈應(ying)亮，電極壓力大(da)小(xiao)可(ke)調(diao)整彈(dan)簧壓力螺母，改變其壓縮程度(du)而獲得。

3、在完成上(shang)述調整后(hou)，電(dian)(dian)(dian)(dian)池自動可先接通(tong)冷卻水后(hou)再接通(tong)電(dian)(dian)(dian)(dian)源(yuan)準備焊(han)接。焊(han)接過程的程序：焊(han)件置于(yu)兩(liang)電(dian)(dian)(dian)(dian)極之間，踩下(xia)腳(jiao)踏板(ban)(ban)，并使上(shang)電(dian)(dian)(dian)(dian)極與焊(han)件接觸并加(jia)壓(ya)(ya)，在繼續壓(ya)(ya)下(xia)腳(jiao)踏板(ban)(ban)時(shi)，電(dian)(dian)(dian)(dian)源(yuan)觸頭開(kai)(kai)關(guan)接通(tong)，于(yu)是變壓(ya)(ya)器開(kai)(kai)始工作次級回(hui)路通(tong)電(dian)(dian)(dian)(dian)使焊(han)件加(jia)熱。當(dang)焊(han)接一(yi)定時(shi)間后(hou)松開(kai)(kai)腳(jiao)踏板(ban)(ban)時(shi)電(dian)(dian)(dian)(dian)極上(shang)升(sheng)，借彈簧的拉力先切(qie)斷電(dian)(dian)(dian)(dian)源(yuan)而后(hou)恢復原(yuan)狀(zhuang)，單點焊(han)接過程即告結束。

4、焊件(jian)準備及(ji)裝(zhuang)配：鋼(gang)焊件(jian)焊前(qian)須清(qing)除(chu)一切臟物、油污、氧化皮及(ji)鐵銹，對(dui)熱軋鋼(gang)，最好把焊接(jie)處先經(jing)(jing)過酸洗、噴砂或用(yong)砂輪(lun)清(qing)除(chu)氧化皮。未經(jing)(jing)清(qing)理的焊件(jian)雖能進(jin)行點焊，但是嚴重地降低電極的使用(yong)壽命，同時降低點焊的生(sheng)產效(xiao)率(lv)和質量。對(dui)于有薄(bo)鍍(du)層的中低碳鋼(gang)可(ke)以直接(jie)施焊。

二，電池自(zi)動點焊機的使用說明

點(dian)焊(han)機系采用雙(shuang)面雙(shuang)點(dian)過流焊(han)接(jie)的(de)原(yuan)理，工(gong)(gong)作(zuo)時兩(liang)個電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)加壓(ya)工(gong)(gong)件(jian)使兩(liang)層金屬在兩(liang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)的(de)壓(ya)力(li)下(xia)形成(cheng)(cheng)一(yi)(yi)定(ding)的(de)接(jie)觸電(dian)(dian)(dian)(dian)(dian)阻，而(er)焊(han)接(jie)電(dian)(dian)(dian)(dian)(dian)流從一(yi)(yi)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)流經另(ling)一(yi)(yi)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)時在兩(liang)接(jie)觸電(dian)(dian)(dian)(dian)(dian)阻點(dian)形成(cheng)(cheng)瞬(shun)間的(de)熱熔接(jie)，且焊(han)接(jie)電(dian)(dian)(dian)(dian)(dian)流瞬(shun)間從另(ling)一(yi)(yi)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)沿兩(liang)工(gong)(gong)件(jian)流至此電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)形成(cheng)(cheng)回(hui)路，不傷及被焊(han)工(gong)(gong)件(jian)的(de)內部結構。

點焊的(de)工藝過程為(wei)開通(tong)冷卻水;

將焊件表面清理干凈(jing)，裝(zhuang)配準確后，送入上、下電極之間，施加壓(ya)力，使其接觸良好;

通電使兩(liang)工件(jian)接觸表面受熱，局(ju)部熔(rong)化，形成熔(rong)核;

斷(duan)電后保持(chi)壓力(li)，使熔核在(zai)壓力(li)下冷卻凝固形成焊(han)點;

去除壓(ya)力，取出工件(jian)。焊接電(dian)流(liu)、電(dian)極壓(ya)力、通(tong)電(dian)時間及電(dian)極工作(zuo)表面尺寸等點焊工藝參(can)數對(dui)焊接質量有重(zhong)大影響。

電(dian)(dian)(dian)池自(zi)動點焊(han)(han)機利用正負兩(liang)極在瞬間短(duan)路(lu)時產生(sheng)的(de)(de)(de)(de)(de)高(gao)溫電(dian)(dian)(dian)弧來(lai)熔化電(dian)(dian)(dian)焊(han)(han)條上的(de)(de)(de)(de)(de)焊(han)(han)料(liao)和被焊(han)(han)材料(liao)，來(lai)達到(dao)使它們結合的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。電(dian)(dian)(dian)焊(han)(han)機的(de)(de)(de)(de)(de)結構十分(fen)簡單，說白了就(jiu)是一個(ge)大功(gong)率的(de)(de)(de)(de)(de)變壓器，將(jiang)220V交流(liu)電(dian)(dian)(dian)變為低電(dian)(dian)(dian)壓，大電(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)源，可(ke)以是直流(liu)的(de)(de)(de)(de)(de)也(ye)可(ke)以是交流(liu)的(de)(de)(de)(de)(de)。電(dian)(dian)(dian)焊(han)(han)變壓器有自(zi)身的(de)(de)(de)(de)(de)特(te)點，就(jiu)是具(ju)有電(dian)(dian)(dian)壓急劇下降的(de)(de)(de)(de)(de)特(te)性。
