Features

I. AC Pulse

Accurate and fast switching of pulse polarity is achieved by Megmeet's patented algorithm, which integrates high speed and 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 a unique negative stability algorithm, AC MIG is as stable as DC welding;

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

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

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

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

II. AC Short Circuit Transition

• A high-frequency hardware system working with Megmeet's patented algorithm could accurately pre-judge droplet necking. 

• Droplet transition instant polarity is switched to a negative arc, and the droplet flows freely into the fusion pool, which fundamentally eliminates the generation of large-particle spatter and smoke, and ensures high-speed and high-quality welding.

Welding Features:

• High-speed and stable alternation of polarity, softer arc, 90% less spatter than traditional DC welding;
  

• Smooth droplet transition, small fluctuation in fusion pool, and weld shape is more delicate and beautiful;

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

• Ultra-low heat input, to be easily competent in high-quality welding of 0.5mm ultra-thin plates;
  

• Higher deposition efficiency and faster welding speed, and wire feeding speed is increased by 20% under the same current;
  

• Arc energy is low and dust amount during welding is small.

III. High-Speed DC Welding

• With a wider adaptive range of voltage, the same current is able to match lower voltage (10% lower than other welding machines);

• Lower heat input, higher deposition efficiency, and thin-plate welding performance are comparable with tap-type machines.
  

  
  

IV. Wire Retraction Function in Arc Starting

• When the welding machine detects an arc starting signal, the wire will retract at high speed, greatly improving the quality and success rate of arc starting and reducing various arc staring issues.
  
  

V. Up-down Torch (optional)

• An up-down torch is optional to conveniently adjust welding parameters on the torch(current, voltage, etc).
  

VI. 400V High-voltage Touch Sensing Function

• Built-in high-voltage touch sensing function with adjustable range 80~400V, no need to separately buy high-voltage touch sense device;
  

• High reliability and effective penetration of oil stains, rust, water stains, etc., fast touch-sense with high precision, and strong adaptability to robots;
  

• The current-limiting design ensures welding within a safe current range, effectively protecting the safety of welders and welding machines;

  

VII. Intelligent Upgrade

With an additional robotic accessories package, the manual-type welding power source can be expanded to a robotic welding power source to help users save money.

VIII. High Reliability

• Strong environmental adaptability, suitable for working under tough environments; 
  

• Stable and reliable: stability is the base of intelligent welding machines!
  

• Consistency: consistent performance by any machine, anytime and anywhere!

IX. Water Cooler (Optional)
