ARC Series Inverter DC MMA Welding Machine (IGBT Module)

Rated input voltage(V) :AC380V+/-15% Rated input current(A) :21 28 38 52 No-load voltage(V) :79 1. Technology parameterIt uses advanced invert technology and powerful switch design (IGBT). It has the perfect 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 blance automatic when voltage is waving, with high resist to electrical wave(V±15%), moreover welding perfect with 100m output cable. It is small and light, easily work in high alitude. 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.When switching to stick welding(MMA),down war welding function is available on cellulose welding electrode. Normal Accessories:Earth clamp 1pcs, fast joint 2pcs, allen-key 1pcs.2. Specification ParamterARC-315 (ZX7-315)ARC-400 (ZX7-400)ARC-500 (ZX7-500)ARC-630 (ZX7-630)
