适用行业：Construction machinery, metallurgy, steel structure, petroleum, chemical industry, shipbuilding, pressure vessels, automobiles, bridges, electric power, railways, boilers, etc.
Main Features
■ Specially suitable for no-spatter welding of aluminum and its alloy
■ Support single-pulse MIG welding, and double-pulse MIG welding.
■ Soft-switch inverter technology, DSP all-digital control, LCD menu and function display, can be used with robot
■ With welding expert database inside, can save 30 sets of parameters
■ Automatic protection from over-current, over/under-voltage and over temperature
■ With all-closed grating feedback four-wheel double-driving wire feeder
■ Double-pulse MIG welding greatly decreased the technical requirements for welders and the labor intensity of welders. Every fish-scale fatten can form automatically and evenly and the size of fish-scale fatten can be controlled
■ Can weld aluminum with a thickness of 1.0mnm
