NB-350/500B2 inverter gas shielded welding machine
main features
IP23S level protection function: capable of withstanding water spray within a ± 60 ° angle range with the plumb line; Strong adaptability and higher safety for shipbuilding and outdoor operations
Equipped with a standard four-wheel dual drive wire feeder, the wire feeding is both fast and stable: the speed can reach 1-22m/min, with greater wire feeding thrust and smoother wire feeding, reducing the possibility of poor wire output caused by long or excessively bent welding gun cables
NB-500B2 is equipped with two 1000 μ F high-capacity electrolytic capacitors, which have strong resistance to grid fluctuations and are suitable for generator power supply
Dual use: NB-350/500B2 gas shielded welding with manual welding function, enhancing on-site emergency response capabilities
Equipped with high-quality IGBT modules, stable high-power output, and better overall stability of the machine
Personalized arc characteristics to meet different operating habits
The arc current and arc voltage are independently adjustable and use different welding processes
Overheating automatic protection function, when overloaded, malfunctioning, or abnormal overheating occurs inside the power supply, the welding machine stops outputting and is automatically protected
Voltage abnormality protection: When the supply voltage is below the rated voltage range, the abnormality indicator light will turn on and the welding machine will shut down the output
Product application
Suitable for all position welding of carbon steel parts using CO2/MAG welding method;
Especially suitable for outdoor workplaces such as construction, bridge steel structures, engineering machinery, shipbuilding, outdoor installation and maintenance.
