Soft-switch inverter technology, all-digital DSP control, world-advanced level

With welding expert database inside, can save 30 sets of self-set parameter

Automatic protection from over-current, over/under-voltage, over-temperature

All-digital LCD menu to show functions and data, synergic adjustment supported, easy to operate

With one-pulse one-drop control system, all-closed wire feeder optical grating feedback control

Support MAG, pulse MAG, double-pulse MAG, pulse MIG, double pulse MIG welding

Support single/double-pulse welding to carbon steel, stainless steel, aluminum, galvanized steel plain sheet, copper, and so on, seam beautiful, can realize low-spatter and no-spatter welding

While double-pulse welding is adopted, it greatly decrease the technical requirements for welders and welder′s work force, each ripple can automatically generate evenly

Can support welding of aluminum and its alloy with a thickness of over 1.2mm with aluminum wire with diameter of 1.2mm

Equipped with water-cooling torch, high-efficiency cooling water tank, all-closed wire feeder
