II. Quick Pulse Technology (QPT)

Unique quick pulse welding technology adopts a three-level main power topology. High-speed sampling and control advantages, brought by the inverter frequency up to 110kHz, can reach a critical state between short circuit and pulse spray transition.
With shorter droplet transition distance, lower arc, and faster welding speed, pulse speed is increased by more than 20%. The service life of wearing parts is lengthened and the weld shape is better, meeting the actual needs of manual welding.

Pain Points in Conventional Pulse Welding	VS	Megmeet Quick Pulse Technology(QPT)
Speed is slow: 30% slower than DC welding Weld formation is difficult to control: high heat input, long arc, and many undercuts High Requirements in Mixed Gas: high requirements in the 80/20 gas ratio and resulted in higher cost Accessories Loss: high voltage and high pulse peak value bring serious heating to the torch and the high cost of accessories and shorter service life.	VS	Welding speed is faster and welding speed is increased by 20%, compared with conventional pulse; Short arc length, good stiffness, strong anti-interference ability, more suitable for high-speed welding of medium and thick plates, supporting concentrated arc energy and better penetration; Low arc heat input increases the service life of accessories; Wide voltage range, strong welding adaptability, simpler operation, more popular by welders.

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.
