NB series MIG/MAG IGBT inverter welding machine

Using soft-switch inverting technology and special waveform control , NB series welding machine have the excellent welding on the full range of welding current, even though the max.&mildle&min welding current. For example, the 500A welding machine shows the very stable welding capability while the Φ1.2mm welding wire are used. The series with extra ouput energy are suitable for the use on the extra long weld cables, even if the length is 50m. Main Feature: With soft-switch IGBT inverting technique, the power sources working is over 20KHZ, have excellent dynamic and . It is small volume, light weight and convenient to move. High efficiency, remarkable energy-saving effect over the same specifications of the power-saving SCR welder more than 25 percent in line with the country energy-saving requirements. Presetting and indicating of welding current/voltage with LED digital display, conveniently, direct-viewing, quickly.Using closed-loop negative feedback control, it is high precision of the system , excellent anti-fluctuation in stable welding arc, easy to weld crater control, handsome weld forming. With special wavefrom control, it is arc adjustment, less welding spatter, weld forming. Optimizing striking parameters and slow feeding wire make stable starting arc from the high success rate. With excellent arc self-regulating capacity, welding arc can remain stable while wire extention is changed. The machine has a long / short Weld conversion feature, respectively, apply to the long and short of the welding seam, and to labor intensity lessening.Filling crater and auto cutting-ball feature can improve weld quality and the success rate of the arc-striking. Using the the power input current detection, it is high-reliability design, fast response speed safe and reliable. NB-500F with an independent cooling wind path, patented technology (200520034327.7), can be used in the field of the poor environmental conditions (waterproof, dustproof). NB-500L welder with ordinary rubber tracheal and welding cables, using a cable wide-remoter,is much lower cost than the using the carrier remote control, and better reliability.
