MD-25 mid-frequency inverter resistance welding machine

MD-25 Intermediate frequency welding machine ISO9001:2000 CCC Juntengfa is one of China's top ten welding manufacturer MD-25 Intermediate frequency welding machine description:1.Welding current for the DC,when the secondary windings in the induction/a magnetic material will not be affected by welding. 2.So that the load-balancing power supply equipment:frequency inverter welder convex point on the use of three-phase power grid voltage drop fluctuations and greater adaptability.3.More precise,fast current control:frequency systems and more,a more accurate analysis of parameters.4.Faster to set up current:IF in the regulation of welding current technology faster than traditional 20-fold.5.Process more reliable:the majority of the application of solder DC welding metal effect will be even better.6.Reduce operating costs,including energy savings each and every point of welding as well as shortening the welding cycle.7.Save energy:especially suitable for welding thick workpieces and high-conductivity metal.such as aluminum and galvanized steel sheet,such as all.MD-25 Intermediate frequency welding machinePrimary technical parameters:
