Dex2 Ultra 400AC

​  Product Features

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

  • Arc energy is controllable and effectively suppresses the generation of welding fumes. Glossiness of Al-Mg welding is as good as Al-Si welding with 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 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

AC Pulse

Accurate and fast switching of pulse polarity is achieved by Megmeet patented algorithm, which integrates high speed & high efficiency of MIG welding with high quality of TIG welding, greatly optimizes welding production efficiency and welding quality.

Welding Features:

  • High inverter frequency, more stable arc, higher precision;

  • With unique negative stability algorithm, AC MIG is as stable as 
    DC welding; 

  • Full-process heat input management, precise control of 
    penetration depth, to be easily competent in high-quality welding of 0.5mm ultra-thin plates;

  • By adjusting EN/EP ratio, wire melting speed can be dynamically regulated to realize higher deposition rate and higher welding efficiency; 

  • Gap tolerance is high and bridging ability is good, suitable for 
    welding of large-gap lap joints and uneven gaps; 

  • Welding fume is greatly reduced without black smoke deposition on welding seam, and welding surface is more beautiful.

AC Short Circuit Transition

High-frequency hardware system working with Megmeet patented algorithm could accurately pre-judge droplet necking. Droplet transition instant polarity is switched to negative arc, and droplet flows freely into fusion pool, which fundamentally eliminates the generation of large-particle spatter and smoke, and ensures high-speed and high-quality welding.
