HTaaNB250 is CO2 welding machine adopt the advanced IGBT soft switch technology which reduce the switch stress and switch losses

HT-NB350 is CO2 welding machine adopt the advanced IGBT soft switch technology which reduce the switch stress and switch losses improve the machine reliability. This model inverter welder has the good static and dynamic performance.

With constant voltage and constant current invert output function weld the stainless steel, high carbon steel, copper, aluminum and other material with good appearance. It widely used in steel construction, Petroleum Chemical, vehicle, shipbuilder and other machinery manufacturing line.

Double IGBT soft switch ensure the welding stable

inverter technology, constant voltage and constant current control system making welding reliable.

20% Strong power fluctuation resistance even under input voltage 300V still can work. Save energy 20%

Strong pulse arc electronic reactor control system makes small flash, good performance.

Small size, light weight, low maintenance cost

Reset the weld parameters is convenient to weld

Power factor correction technique with high efficiency

Digital display working status can be read clearly.

With 4 wheel 2 drive feeder makes feeding stable.
