ARC Series Inverter DC MMA Welding Machine(MOSFET)

Rated input voltage(V) :AC220V+/-15% AC380V+/-15% Rated input current(A) :32 15 20 28 32 No-load voltage(V) :60 70 1.Technology parameterIt 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. Normal Accessories:Earth clamp 1pcs, fast joint 2pcs, allen-key 1pcs.2.Specification ParaamterARC-200(ZX7-200)ARC-250(ZX7-250)ARC-315(ZX7-315)ARC-400(ZX7-400)ARC-500(ZX7-500)
