Invert type NB series CO2 Gas Shielded Welder, including types of 350, 500,is used for all-position welding of medium and thin-sheet metal, such as medium carbon steel, low carbon steel, low alloy steel and stainless steel. Push wire/wire drawing.

• Use waveform control technique to improve the molding and reduce the splash.
• High welding deposition rates
• Use for solid cored wire and flux-cored wire.
• Have the function of eliminating ball when retreat the arc.
• Little welding deformation and good weld formation.
• Soft switches conversion and high efficiency of the whole machine.
• High frequency inverter, small volume and light weight.
• The current and voltage are continuously tunable with wide adjusting range.
• Digital display header and precise presupposition of welding parameter
• High load succession rate and continuous welding for a long time
• Slow wire feeding and arc ignition with easy arc ignition and high success rate
• Passive power factor correction technique and high power factor
