NB系列 晶闸管控制CO2/MAG半自动气体保护焊机
Crystal gate tube control CO2/MAG semi-automatic gas protective welder

    本系列焊机吸收外国焊机的先进性能。其规格200A、350A、500A三种。根据焊接材料的不同，可采用二氧化碳气体或混合气体作为保护介质进行焊接。具有飞溅小，熔深比大，操作简便、焊缝成形好等特点。
    This series welder absorbs the advanced performance of the foreign welder, with three specifications 200A,350A and 500A. According to the different welding materials, if adopts the carbon dioxide gas or mixed gas to be the protective medium to carry out the welding. It possesses the merits of small splash, large melting depth rate, simple operation and good weld-seam shaping etc.

■焊丝削球和高电压、缓送丝功能，提高了引弧的可靠性。
■电压反馈控制，对电网电压波动能自动补偿，使焊接电弧稳定。
■实芯/药芯焊丝切换和收弧选择功能。
■节能设计，焊接停止，气路、电路自动关闭。
■Wire clipping-ball and high voltage, slow wire sending function the arc-starting liability.
■Voltage feedback control can automatically compensate to the distribution voltage wave and let the welding electric arc stability.
■Solid core/drug core welding wire conversion and arc-receiving function.
■Energy-saving design, welding stop, gas, circuit and electric automatically close.
