鐵路局專用230A發(fā)電電焊兩用機價格/報價  直流電焊機與交流電焊機的區(qū)別？都是靠短路電弧來進行焊接的，但直流焊更穩(wěn)定，用于要求高的場合： 　　
The difference between the dc arc welding machine and ac arc welder? Are to be carried out by a short circuit arc welding, but more stable dc welding, used in occasions with higher requirements: 
一、直流電焊機輸出的電流沒有“過零點”，不易斷弧，電弧穩(wěn)定，這是它zui大的優(yōu)點。鐵路局專用230A發(fā)電電焊兩用機價格/報價 　　
A, dc electric welding machine output current is not "zero", not easily broken arc, arc stability, this is it zui big advantages.  
二、變壓器二次電壓峰值一定，直流電焊機比交流電焊機空載電壓高，更容易引弧。 　　
Second, the transformer secondary voltage peak must be, dc arc welding machine is higher than ac arc welder no-load voltage, arc more easily.  
三、直流電焊機比交流電焊機多出整流部分，成本要稍高一些。 　　
Three more than ac arc welding machine, dc welding machine rectifier part, the cost is somewhat higher.  
四鐵路局專用230A發(fā)電電焊兩用機價格/報價 、大功率的交流電焊機由于zui多只能用到兩相電，所以容易造成三相用電不平衡，而大功率的直流電焊機都用三相整流就沒有這個問題。 　　
Four, high-power ac arc welder as zui can only use two phase more electricity, so easy to cause the unbalanced three-phase power, and high power dc arc welding machine with three-phase rectifier is not the problem.  
五、焊條使用跟焊接材料有關而跟焊機無關。
Five, the electrode using associated with welding material and has nothing to do with welding machine.
