不过CO_2焊射滴过渡只能发生在潜弧状态下，产生潜弧的条件为在CO_2气氛中，使用粗焊丝，大电流和低电压的配合参数。
The condition inbwhich the arc is buried are that the parameters such as CO_2 gas, thick wire, high current and low voltage should be used.
晶闸管逆变弧焊电源具有单管导通电流大、耐压高、正向压降低、过载能力强等特点，但在使用过程中会出现各种故障。
Thyristor inverter welding power source with single-conduction high current, high breakdown voltage, low positive voltage drop and the high over load etc.
