Functions:
◆ Two welding wires are mixed back and forth at a certain angle. The welding current of the front wire is relatively high, which is conducive to forming a larger penetration depth. The current of the back wire is slightly small, which plays a role in flling the cover surface.

◆ Two welding wires heated each other, fully utilizing the energy of the arc to achieve a higher deposition rate, allowing sufficient fusion of molten metal and base metal in the molten pool, resulting in a beautiful weld formation.

◆ Greatly enlargement the size of the molten pool, The gas in the molten pool has sufficient time to precipitate, and the tendency of pores is extremely low.

◆ Although this welding method has a high current, the welding speed is fast, so the heat input is actually small and the welding deformation is also very small. Compared with other welding techniques, the deposition speed is faster，higher welding efficiency, better welding quality, and less spatter.

◆ The power supply for both arcs is fully digital, with simple operation and flexible setting of the host and slave states. The welding parameters are easy to match, and each parameter of each pulse arc can be accurately adjusted to obtain the best heat input distribution, resulting in good formed welds and stable penetration.

◆ For thin plate welding, the main goal is to improve the welding speed. By using high-speed double wire MIG/MAG welding, the distribution of welding Temperature field and arc force has been improved due to changing the arc shape, which can significantly increase the welding speed and improve the weld formation.
