Rated input voltage(V):AC220V+/-15%,AC380V+/-15% Rated frequency(Hz):50/60 Rated input current(A):32 14.4 20 28 32 1.ApplicationIt adopts MOSFET invert technology, high frequency arc start design.It can balance automatic when voltage is waving, with high resist to electrical wave(V±15%).It has high efficiency, small unload loss, save over 40% than the traditional welder.It is small and light, easily work in high altitude.It is easily arc, small flash, low noise stable welding arc, wonderful welding shape.With inner stalling protective circuit of over-heat, over-current, over-voltage and under-voltage, working safe is reliable.Dual functions welder, TIG for arc root welding and MMA for arc cap welding. Normal Accessories: Earth clamp 1pcs, earth cable 2m, allen-key 1pcs, TIG torch 1pcs. 2.Specification ParameterTIG-200(WS-200)TIG-250(WS-250)TIG-315(WS-315)TIG-400(WS-400)TIG-500(WS-500)
