1. 減壓器
減壓(ya)(ya)器又稱壓(ya)(ya)力調節器，其作用是把儲存在氣(qi)(qi)瓶內的高壓(ya)(ya)氣(qi)(qi)體(ti)減壓(ya)(ya)至焊接或切(qie)割(ge)所(suo)需的壓(ya)(ya)力，并保持壓(ya)(ya)力穩定(ding)。國產(chan)幾種常用氣(qi)(qi)體(ti)減壓(ya)(ya)器型號及技(ji)術參數見表2-37。
2. 流量計、氣(qi)體配比器
流量的大小(xiao)將(jiang)對焊(han)接接頭質量有很大影響，轉(zhuan)子流量計是氣(qi)體(ti)(ti)保(bao)護(hu)焊(han)中調節保(bao)護(hu)氣(qi)本流量的一種儀器。對于(yu)混合氣(qi)體(ti)(ti)保(bao)護(hu)焊(han)還(huan)需(xu)氣(qi)體(ti)(ti)配(pei)比(bi)器，來控制不同(tong)氣(qi)體(ti)(ti)流量的裝置。
有關轉子流量計和(he)氣體配比器的型號(hao)及(ji)技術數據(ju)見(jian)表2-38和(he)表2-39。
3. 手工鎢極氬(ya)弧焊焊槍(qiang)
手工(gong)(gong)鎢極氬弧焊(han)(han)(han)(han)(han)焊(han)(han)(han)(han)(han)槍是(shi)(shi)手工(gong)(gong)氣(qi)(qi)(qi)體保(bao)(bao)護(hu)焊(han)(han)(han)(han)(han)在(zai)使用(yong)(yong)過程中(zhong)(zhong)(zhong)(zhong)不可缺少的(de)一(yi)種(zhong)(zhong)工(gong)(gong)具。它除了具有焊(han)(han)(han)(han)(han)條電弧焊(han)(han)(han)(han)(han)用(yong)(yong)焊(han)(han)(han)(han)(han)鉗的(de)性(xing)能(neng)外，還(huan)要求焊(han)(han)(han)(han)(han)槍輕(qing)便(bian)、靈活，便(bian)于焊(han)(han)(han)(han)(han)工(gong)(gong)在(zai)不同位置長時間(jian)(jian)不間(jian)(jian)斷地工(gong)(gong)作，以及具有良好的(de)絕緣性(xing)，保(bao)(bao)證(zheng)使用(yong)(yong)者安全。手工(gong)(gong)鎢極氬弧焊(han)(han)(han)(han)(han)焊(han)(han)(han)(han)(han)槍通常有兩種(zhong)(zhong)：一(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)(qi)冷(leng)式，另一(yi)種(zhong)(zhong)是(shi)(shi)水冷(leng)式。對(dui)于水冷(leng)式焊(han)(han)(han)(han)(han)槍要保(bao)(bao)證(zheng)水流(liu)暢通，不能(neng)有堵(du)塞(sai)和(he)滲(shen)漏現象，不然(ran)在(zai)施(shi)焊(han)(han)(han)(han)(han)過程中(zhong)(zhong)(zhong)(zhong)突然(ran)中(zhong)(zhong)(zhong)(zhong)斷除會影(ying)(ying)響正常施(shi)工(gong)(gong)外，還(huan)會對(dui)焊(han)(han)(han)(han)(han)接(jie)質量(liang)造成(cheng)極大(da)的(de)影(ying)(ying)響。氣(qi)(qi)(qi)冷(leng)式焊(han)(han)(han)(han)(han)槍的(de)氣(qi)(qi)(qi)管(guan)同樣要保(bao)(bao)持氣(qi)(qi)(qi)流(liu)暢通，特別(bie)是(shi)(shi)新焊(han)(han)(han)(han)(han)槍使用(yong)(yong)前，要將氣(qi)(qi)(qi)管(guan)中(zhong)(zhong)(zhong)(zhong)殘留多余物(wu)吹除干(gan)凈，這樣才能(neng)保(bao)(bao)證(zheng)輸(shu)送氣(qi)(qi)(qi)體的(de)純度(du)，不然(ran)將會直接(jie)影(ying)(ying)響焊(han)(han)(han)(han)(han)接(jie)接(jie)頭質量(liang)。
常用的氣(qi)冷(leng)式和水冷(leng)式焊槍型號和技術數(shu)據見表2-40。
