普通電(dian)焊(han)機和(he)相比有哪些特點(dian)呢

點焊機分(fen)交流點焊機和電(dian)容(rong)(rong)儲(chu)能(neng)點焊機兩(liang)種。前者用(yong)大(da)變(bian)壓器+半導體可控(kong)開(kai)關控(kong)制(zhi)(zhi)導通(tong)時間，借(jie)以控(kong)制(zhi)(zhi)點焊能(neng)量，不太適合業(ye)余條件(jian)制(zhi)(zhi)作(zuo)。后者用(yong)大(da)電(dian)容(rong)(rong)，利用(yong)并聯的電(dian)容(rong)(rong)數量或者通(tong)過充(chong)電(dian)截止(zhi)電(dian)壓來控(kong)制(zhi)(zhi)點焊能(neng)量，點焊能(neng)量=0.5 * V^2 * C， 比較適合業(ye)余制(zhi)(zhi)作(zuo)。 

點焊機，原理如(ru)下：220Vac經變壓器調整為200Vac，再經方(fang)橋整流，由(you)可控硅調角(jiao)向68000UF*2個電(dian)容充電(dian)，電(dian)容有電(dian)壓反饋信(xin)號來(lai)截止充電(dian)。 

電(dian)(dian)容(rong)(rong)放(fang)電(dian)(dian)是(shi)點(dian)焊機(ji)的(de)一種，低壓(ya)(ya)、大容(rong)(rong)量。一般(ban)都是(shi)做成(cheng)可調的(de)，電(dian)(dian)壓(ya)(ya)幾(ji)十伏(fu)，電(dian)(dian)容(rong)(rong)要0.3mF左右，因此這樣的(de)電(dian)(dian)容(rong)(rong)要10多個并聯(lian)。 

用(yong)(yong)點焊機焊接鋼帶，他的(de)原理就是把變壓器(qi)(qi)次極的(de)2條(tiao)線用(yong)(yong)2根銅棒做焊極，下(xia)面(mian)的(de)不(bu)動，上面(mian)的(de)銅棒用(yong)(yong)一腳踏(ta)開(kai)關(guan)(guan)控(kong)制(zhi)，腳踏(ta)下(xia)的(de)同時，也有(you)一個輔助(zhu)開(kai)關(guan)(guan)去(qu)接通變壓器(qi)(qi)初級，當(dang)然中間(jian)還(huan)有(you)一個可以(yi)調節的(de)時間(jian)繼電(dian)器(qi)(qi)！焊接電(dian)流由(you)時間(jian)繼電(dian)器(qi)(qi)控(kong)制(zhi)！很是方便！ 

因(yin)為(wei)(wei)220V輸(shu)(shu)入的(de)電(dian)(dian)(dian)(dian)流(liu)根本就(jiu)不大(da)！我們來(lai)簡單計算(suan)一(yi)(yi)下(xia)，500W的(de)變(bian)壓器(qi)220V電(dian)(dian)(dian)(dian)流(liu)大(da)概2。3A左右(you)，而輸(shu)(shu)出的(de)電(dian)(dian)(dian)(dian)壓很(hen)低，2V左右(you)，就(jiu)算(suan)剛好功(gong)率(lv)為(wei)(wei)500W，那(nei)么電(dian)(dian)(dian)(dian)流(liu)就(jiu)應該是(shi)250A，看上去電(dian)(dian)(dian)(dian)流(liu)是(shi)很(hen)大(da)，但是(shi)那(nei)是(shi)次(ci)級，在輸(shu)(shu)入級就(jiu)只有2。3A左右(you)了(le)！看過很(hen)多電(dian)(dian)(dian)(dian)焊機都是(shi)使(shi)(shi)用(yong)電(dian)(dian)(dian)(dian)容儲能的(de)！和閃(shan)光燈一(yi)(yi)樣，它也(ye)得使(shi)(shi)用(yong)專(zhuan)用(yong)的(de)電(dian)(dian)(dian)(dian)容，一(yi)(yi)般的(de)大(da)容量(liang)電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容器(qi)是(shi)不適(shi)合適(shi)合點焊機使(shi)(shi)用(yong)的(de)（主(zhu)要是(shi)因(yin)為(wei)(wei)普(pu)通(tong)的(de)電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容器(qi)的(de)放電(dian)(dian)(dian)(dian)速率(lv)會嚴重(zhong)影響普(pu)通(tong)電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容器(qi)使(shi)(shi)用(yong)壽(shou)命(ming)！）對于點焊機電(dian)(dian)(dian)(dian)容器(qi)，國外幾家著名的(de)電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容器(qi)生產(chan)商都有相(xiang)關(guan)的(de)產(chan)品，建議有興(xing)趣的(de)朋(peng)友(you)去弄幾個(ge)來(lai)試(shi)一(yi)(yi)試(shi)！！

隨(sui)著中(zhong)頻逆(ni)(ni)變點焊(han)機電(dian)源(yuan)(yuan)應用(yong)到自(zi)(zi)動(dong)、半方面的(de)進(jin)一步(bu)研究，功率(lv)逆(ni)(ni)變組件(jian)可(ke)靠(kao)性(xing)的(de)提高，逆(ni)(ni)變點焊(han)機將(jiang)得到較(jiao)大的(de)發展。 逆(ni)(ni)變式焊(han)接(jie)(jie)電(dian)源(yuan)(yuan)由于具有(you)焊(han)接(jie)(jie)性(xing)能好(hao)、動(dong)態(tai)反應速度快、動(dong)特(te)性(xing)好(hao)、效(xiao)率(lv)高、焊(han)接(jie)(jie)速度高、多功能、有(you)利于實現(xian)焊(han)接(jie)(jie)機械化(hua)(hua)、自(zi)(zi)動(dong)化(hua)(hua)和(he)(he)智(zhi)能化(hua)(hua)的(de)優點，已(yi)成(cheng)為阻(zu)焊(han)電(dian)源(yuan)(yuan)的(de)發展方向。據(ju)不完全統計，近年來，我國逆(ni)(ni)變焊(han)機在(zai)品種、規(gui)格不斷(duan)增加的(de)同(tong)時，其(qi)產量和(he)(he)銷售量每年以近10％的(de)速度增長。

我們還應注意到(dao)，用戶會不斷給專(zhuan)用成(cheng)套(tao)設(she)備提(ti)出更高(gao)(gao)的(de)(de)要求(qiu)，我國的(de)(de)成(cheng)套(tao)焊接(jie)設(she)備制造企(qi)業(ye)(ye)不但(dan)要在(zai)(zai)提(ti)高(gao)(gao)技術、設(she)計水平上做出努力(li)，還要在(zai)(zai)企(qi)業(ye)(ye)質量管理、各種(zhong)基礎(chu)件(jian)、配(pei)套(tao)件(jian)的(de)(de)選用方(fang)面(mian)(mian)投(tou)入下功夫，爭取在(zai)(zai)專(zhuan)用、成(cheng)套(tao)焊接(jie)設(she)備方(fang)面(mian)(mian)取得新(xin)的(de)(de)突(tu)破。
