Features
■ 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, easy to operate
■ Support high-quality welding of stainless steel, titanium, nickel, copper, carbon steel, and its alloy, seam beautiful
■ While doing welding, it is not necessary to do beveling or to leave space. The seam can be formed once a time. Energy saving, rapid and high efficiency.
■ Adopting the special cooling design, the plasma torch can support long-term big-current welding, arc is centralized and the penetration force is strong
■ All-digital control of plasma gas flow, easy to operate
■ DSP all-digital control of production and control of plasma arc, thus beautiful plasma arc can be got without needing mixed gas
■ Beautiful seam, high qualification rate, automatic wire filling according to the requirements
■ Equipped with water-cooling torch, high-efficiency cooling water tank, automatic welding trolley
