1. 減(jian)壓器


  減(jian)壓(ya)器又稱壓(ya)力(li)調節器，其作用是把儲存在氣瓶內的高壓(ya)氣體減(jian)壓(ya)至焊接或切(qie)割所(suo)需(xu)的壓(ya)力(li)，并保持(chi)壓(ya)力(li)穩定。國產(chan)幾種(zhong)常用氣體減(jian)壓(ya)器型(xing)號及技術參(can)數見表(biao)2-37。

2. 流量計、氣體(ti)配比(bi)器


  流量(liang)的大小(xiao)將(jiang)對焊接接頭(tou)質(zhi)量(liang)有(you)很大影響(xiang)，轉子流量(liang)計(ji)是(shi)氣(qi)體保護(hu)(hu)焊中調(diao)節保護(hu)(hu)氣(qi)本流量(liang)的一種儀器。對于混合氣(qi)體保護(hu)(hu)焊還(huan)需(xu)氣(qi)體配比器，來控制不(bu)同氣(qi)體流量(liang)的裝置。


  有關(guan)轉子流量計和氣體配比(bi)器(qi)的型(xing)號及技術數據(ju)見(jian)表(biao)2-38和表(biao)2-39。

3. 手工鎢極氬(ya)弧焊焊槍


  手(shou)工(gong)鎢極氬(ya)(ya)弧焊(han)(han)(han)(han)(han)焊(han)(han)(han)(han)(han)槍(qiang)(qiang)是手(shou)工(gong)氣(qi)(qi)(qi)體保(bao)護(hu)焊(han)(han)(han)(han)(han)在使(shi)用(yong)(yong)過程(cheng)中(zhong)(zhong)不(bu)(bu)可缺少的(de)(de)一(yi)(yi)種(zhong)工(gong)具(ju)(ju)。它除(chu)(chu)了具(ju)(ju)有(you)焊(han)(han)(han)(han)(han)條電弧焊(han)(han)(han)(han)(han)用(yong)(yong)焊(han)(han)(han)(han)(han)鉗(qian)的(de)(de)性(xing)能(neng)外，還要求焊(han)(han)(han)(han)(han)槍(qiang)(qiang)輕(qing)便、靈活(huo)，便于(yu)焊(han)(han)(han)(han)(han)工(gong)在不(bu)(bu)同位置長時間不(bu)(bu)間斷地工(gong)作，以及具(ju)(ju)有(you)良(liang)好的(de)(de)絕緣性(xing)，保(bao)證使(shi)用(yong)(yong)者安(an)全。手(shou)工(gong)鎢極氬(ya)(ya)弧焊(han)(han)(han)(han)(han)焊(han)(han)(han)(han)(han)槍(qiang)(qiang)通(tong)常(chang)有(you)兩(liang)種(zhong)：一(yi)(yi)種(zhong)是氣(qi)(qi)(qi)冷式，另一(yi)(yi)種(zhong)是水(shui)(shui)冷式。對于(yu)水(shui)(shui)冷式焊(han)(han)(han)(han)(han)槍(qiang)(qiang)要保(bao)證水(shui)(shui)流暢通(tong)，不(bu)(bu)能(neng)有(you)堵塞(sai)和滲漏現象(xiang)，不(bu)(bu)然(ran)在施焊(han)(han)(han)(han)(han)過程(cheng)中(zhong)(zhong)突然(ran)中(zhong)(zhong)斷除(chu)(chu)會影(ying)(ying)響(xiang)正常(chang)施工(gong)外，還會對焊(han)(han)(han)(han)(han)接質量(liang)造成極大的(de)(de)影(ying)(ying)響(xiang)。氣(qi)(qi)(qi)冷式焊(han)(han)(han)(han)(han)槍(qiang)(qiang)的(de)(de)氣(qi)(qi)(qi)管同樣(yang)要保(bao)持氣(qi)(qi)(qi)流暢通(tong)，特別是新焊(han)(han)(han)(han)(han)槍(qiang)(qiang)使(shi)用(yong)(yong)前(qian)，要將(jiang)(jiang)氣(qi)(qi)(qi)管中(zhong)(zhong)殘留(liu)多余(yu)物吹除(chu)(chu)干凈，這(zhe)樣(yang)才能(neng)保(bao)證輸(shu)送氣(qi)(qi)(qi)體的(de)(de)純度，不(bu)(bu)然(ran)將(jiang)(jiang)會直接影(ying)(ying)響(xiang)焊(han)(han)(han)(han)(han)接接頭質量(liang)。
