MD-20 MD frequency inverter resistance welding machine 3C, ISO9001:2000 can save 50% electricity than normal spot welder

  MD-20 MD frequency inverter resistance welding machine

description1.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-20 MD frequency inverter resistance welding machinePrimary technical parameters
