Good active function, reliability arc starting, stable voltaic arc, little spatter Real heavy load special machine, it can be easy competent for the place of big intensity. It has the function of thrust current, blow force current and interruption arc; it has auto compensation function to network voltage fluctuation and the current adjustment range is wide. Wide suitable range, it can weld mild steel, medium carbon steel, alloy steel and stainless steel with different kinds of welding rod The ascendant performance is showed by carbon arc gouging and auto submerged arc welding power It is widely used in steel structure,, petrochemical industry, ship building and mechanism manufacture for welding thick plate of mild steel and dead-hard steel, etc. typeZX5-400ZX5-500ZX5-630ZX5-800ZX5-1000ZX5-1000RZX5-1250rated input voltage3 308V 50HZrated input capacity23KVA30KVA47KVA55KVA67KVA89KVA83KVAno-load voltage63V63V72V72V72V80/90V72Vrated load cycle100%80%100%80%100%100%80%rated output current400A500A630A800A1000A1000A1250Acurrent range40-400A50-500A60-630A80-800A150-1000A150-1000A250-1250Aweight160KG200KG300KG380KG520KG820KG580KGdimension760*450*800940*570*1001060*620*1170
