NBG-500 welding machine adopts fulf bridge IGBT inverter technology and electronic reactor control, to ensure the stability and high quality of welding arc. this technique not only provides current mode control, but also ensures the stability of welding aro, reduces spatter, deepens the weid pool, makes the weld forming beautiful, improves the welding efficiency the application of inverter technology ensures that the welding voltage is still highly stable under the condition of power grid voltage fluctuation and arc length change. are self-regulation ability is strong. further enhances the stability of the welding process NBG-500 we/ding machine has high efficiency welding function, greatly shorten the welding time, improve production efficiency. At the sane time, the welding machine uses carbon dioxide as a protective gas, to avoid the influence of air on the welding. thus obtained higher welding quality and better mechanical properties
