1.ApplicationIt uses advanced invert technology and powerful switch design(IGBT).With 2T & 4T functions.When switching to stick welding(MMA), downwar welding function is available on cellulose welding electrode.It has the pertfect functions in over-voltage, under-voltage, over-current and over-loaded.It has high efficiency, small unload loss, save over 1/3 than the traditional welder.It can balance automatic when voltage is waving, with high resist to electrical wave (V±15%).It is easily arc, small flash, low noise, which can improve working surrounding.That above 500A can dig by compressed air and arc of carbon stick.It is used for welding various of stainless steel, carbon steel, alloy steel, brass and titanium and so on.Dual functions welder, TIG for root welding and MMA for arc cap welding.Normal Accessories:Earth clamp 1pcs, fast joint 2pcs, earth cable 2m, allen-key 1pcs, water cooled TIG torch 1pcs. 2.Specification
