          名字:NB-350/500/630

          性能特点:

          ●Soft switching technology has greatly improved the service life and reliability of the welding machine.

          ●Soft switching technology has greatly improved the service life and reliability of the welding machine.

          ●Using inverter technology, good dynamic response to ensure a smooth welding, 20KHZ high frequency control to make each detail more perfect welding;
          ●The new arc control technology to make the arc better performance, can adjust the arc soft, choose your most comfortable arc;
          ●Welding conditions of a wide range of regulation, high speed welding performance is excellent and stable;
          ●Output short circuit protection, over voltage protection, over current, over voltage protection, etc.;
          ●Output cable can be lengthened to 50 meters, fully meet the needs in remote welding operation;
          ●The panel function design is reasonable, the welding condition setting is simple, intuitive, easy to operate;
          ●The structure design is reasonable and has good waterproof, dustproof function, can adapt to the needs of the construction environment.
          ●The adaptability of high temperature working environment is particularly prominent.
          ●Closed loop control system can ensure the welding voltage in the power grid voltage fluctuations and arc length change in the case of a high degree of stability, strong arc self adjustment ability, the stability of the welding process.
          ●Small size, light weight, high efficiency and energy saving, high load rate, arc welding rectifier without noise.
          ●Wire feeding circuit adopts high stable power supply, stable wire feeding.
