功能及特點 工業(yè)級可控硅整流弧焊機，用于所有牌號焊條的直流手工電流焊接，特別適合于堿性低氫型焊條焊接重要的低碳鋼、中碳鋼以及普通低合金的配件，有利于進行全位置的焊接。效率高、耗能低、噪音小，是推薦的節(jié)能機電產(chǎn)品之一。 焊機利用可控硅元件快速控制的特點，焊機動特性優(yōu)良、性能柔和、電弧穩(wěn)定、熔池平靜、飛濺小、焊縫成型好，有利于克服堿性焊條在焊接過程種產(chǎn)生氣孔的傾向。焊機具有引弧電流及推力電流裝置，使引弧容易及焊條不易粘住。焊機對電網(wǎng)電壓波動進行補償，并在焊機冷熱態(tài)時都能保持焊接電流的穩(wěn)定。焊機操作方便，可遠距離調(diào)節(jié)焊接電流。 ZX5 series thyristor controlled arc welding machine mabe by our plant can be used in direct current manual welding with welding rods of different brands.It’s especially suitable to the welding of key low carbon steel,medium carbon steel and common low alloy fittings with alkaline low hydrogen type welding rods.with the features of high efficiency,less consumption and low noise,it is one of the energy-saving mechanical and electrical products recommended by the country. As the welding machine can make use of the rapid control property of thyristor components,it has favourable features such as good dynamic characteristic,gentle performance,stable arc,calm weld pool,less splatter and perfect weld appearance and can prevent the alkaline welding rod from producing air pores in the course of welding with arc strike current and thrust current device,it makes arc strike easy and the welding rod not inclined to cling.The welding machine can make compensation to the voltage of power grid and maintain the stability of welding current in cold and hot conditions.The welding machine is convenient for operation and the welding current can be regulated by remote control. 技 術(shù) 參 數(shù) TECHNICALDATA　 型號 規(guī)格 ZX5-350 ZX5-450 ZX5-500 ZX5-630 輸入電壓（V） 380V(三相) 380V(三相) 380V(三相) 380V(三相) 頻率 50／60 50／60 50／60 50／60 電流調(diào)節(jié)范圍（A） 35-350 40-450 70-500 80-630 輸出電壓范圍（V） 21.4-34 21.6-38 22.8-40 23.2-45.2 額定負載持續(xù)率（%） 35% 35% 35% 35% 外形尺寸（mm） 725*475*790 725*475*790 745*510*950 745*510*950 重量（kg） 156 160 200 207
