NBC series CO2 MIG/MAG welder Functions & Features: NBC CO2 Arc welder is widely applicable to welding for machine manufacturing, such as automobile and motorcycle parts. Featuring a simple structure, this welder series is divided into 2 types: welding source, electrode feeder and welding gun. The welding source is equipped with a three-phase bridge rectifier circuit and compensation reactor. The electrode feeder is imported from Europe and noted for low inertia, stable electrode feeding, high compactness and low noise. The welding gun is gooseneck-shaped, light, flexible and highly efficient. This welder features high arc stability, little splash & deformation, good-looking welding seams, remarkable energy saving, low production cost, and simple operation & maintenance. technical data:NBC series carbon dioxide welding machines MODELNBC-250(270)NBC-350 Supply voltage: (V/Ph)DC 380/3/50-60DC 380/3/50-60Rated supply energy(KVA)9.818 No-load voltage(V)18-3518-45 Rated duty cycle(%)3535 Rated output voltage(V)18-3518-45 Rated output current(A)50-25060-350 Welding rod dimensions(mm)0.8-1.00.8-1.2 Welding Thickness (mm)1.5-41-5 Wire feed speed(meters/min)18-2318-23 Wire feed TypeIntegrated / SeparateIntegrated / Separate Insulation ClassFF Protection ClassIP21SIP21S Exterior dimension(mm)725*480*780745*510*960 Packing Dimension(mm)760*480*790750*520*970 Weight(KG)87102 AccessoriesIntegrated typeWelding gun : 1 pcWindpipe : 1 pcHose clamp: 2pcsProtective tube 5A,10A: 2 pcs of each.SeparatetypeWelding gun : 1 pcSB-10-I wire feeder 1 pcHose clamp: 2pcsProtective tube 5A,10A: 2 pcs of eachEarth wire (earth clamp included): 1 pcWelding wire 1pc
