Dex2 Ultra Series AC-MIG Welding Machine

Variable Polarity Full Digital IGBT Inverter AC-MIG Welding Machine

Superior welding programs in AC-Pulse MIG, AC short-circuit transition, quick pulse, and others, to easily realize high-performance welding of carbon steel, stainless steel, aluminum alloy, and other materials;

Wire feeding speed is faster and the deposition rate is increased by more than 20%, under the same current;

Patented software algorithm enables high-frequency switching of polarity, low heat input, less spatter, and 0.5mm aluminum alloy welding;

By adjusting the positive and negative polarity ratio of EN/EP, heat input is optimized, and optimal welding of the large-gap bridge can be easily achieved; 

Arc energy is controllable and effectively suppresses the generation of welding fumes. The Glossiness of Al-Mg welding is as good as Al-Si welding with a more beautiful weld shape;

Inverter frequency up to 110KHz enables higher control precision and more stable arc;

Comprehensive communication interfaces are able to communicate with different brands of robots and automation devices;

Touch sensing function with 80-400 voltage is easier to break down the rust on the surface of the workpiece;

IoT interface is reserved to connect with Megmeet SMARC cloud system;

U-disk upgrade function ensures customers to easily obtain Megmeet's most cutting-edge welding technology;

Application industries: precision welding in automobiles and parts, two/tricycles, aerospace, military industry, rail vehicles, new energy, etc.
