在熔化极气体保护焊、特别是在CO_2气体保护焊中,常采用短路过渡形式焊接。而短路频率的高低与焊接电流、焊接电压、回路电感等规范参数以及其他一些工艺因素有关。实践证明、短路频率的高低及稳定在一定程度上可以成为评定焊接电弧稳定性的一个指标。数字式焊接短路频率计具有工作稳定、准确、迅速、直观等优点。可测焊接电压 In the gas shielded welding, especially in the CO 2 gas shielded welding, often used in the form of short-circuit transition welding. The level of short-circuit frequency and welding current, welding voltage, loop inductance and other parameters and other specifications related to technology. Practice has proved that the level of short-circuit frequency and stability to a certain extent, can be a measure of the stability of the arc welding an indicator. Digital welding short-circuit frequency meter with stable, accurate, rapid, intuitive and so on. Measurable welding voltage
