产品特点

    MZ埋弧焊机引入三相电路最小触发角保护控制方法，较好地控制了电源的动特性。因此该设备还可为炼钢、快速淬火设备提供直流输出，较好地弥补了一代产品的不足，特别适合变速送丝的埋弧焊工艺。

    焊机的额定焊接电流对应相应的额定负载持续率，当负载持续率提高时，焊机的最大输出电流相应降低。如负载持续率由60%提高到100%时，最大输出电流为额定焊接电流的0.7746倍。当环境条件超过正常使用环境时，焊机也应降额使用。如果发热试验已在室温下完成，则应通过模拟的方法来确认环境温度40°C条件下的负载持续率。

Product Features

    The MZ submerged arc welding machine introduces a three-phase circuit minimum trigger angle protection control method, which effectively controls the dynamic characteristics of the power supply. Therefore, this equipment can also provide DC output for steelmaking and rapid quenching equipment, which effectively compensates for the shortcomings of the first generation products and is particularly suitable for submerged arc welding processes with variable speed wire feeding.

    The rated welding current of the welding machine corresponds to the corresponding rated load duration rate. When the load duration rate increases, the maximum output current of the welding machine decreases accordingly. When the load duration rate increases from 60% to 100%, the maximum output current is 0.7746 times the rated welding current. When the environmental conditions exceed the normal usage environment, the welding machine should also be downgraded for use. If the heating test has been completed at room temperature, the load duration at an ambient temperature of 40 ° C should be confirmed through simulation.
