Product Advantages
  • 01 Fast Pulse Melting Control, Ultra-low Spatter Forming
    Equipped with multiple modes including single pulse, fast pulse, deep penetration and constant voltage, it realizes precise one-pulse-one-drop transfer with zero welding spatter and aesthetic weld seams. It is suitable for high-efficiency welding of medium and thick plates such as carbon steel, stainless steel and copper alloy.
  • 02 Full-function Integration & Intelligent Collaboration of Robots
    Standard configuration with contact sensing + high-voltage positioning and arc tracking, built-in 100 sets of expert parameter libraries, real-time data interaction, seamless linkage with robots such as FANUC and ABB, plug-and-play for automated production lines.
  • 03 Full-digital grating wire feeding, heavy-load stable welding
    Grating feedback closed loop + dual-drive wire feeding enables zero wire feeding jitter under long cables and fluctuating resistance; with a 100% duty cycle, it maintains full capacity for heavy-duty continuous operation at 400/500A without derating, perfectly adapting to high-intensity welding working conditions.
  • 04 Wide-range stable compatibility, industrial-grade reliability
    380V±15% wide voltage, soft switching inverter, IP23 protection, Class H insulation. Stable output with 50-meter long cables, strong anti-interference capability and low failure rate, suitable for harsh workshop environments such as construction machinery, steel structure and shipbuilding industries.
