NB-250/300B1 inverter gas shielded welding machine
main features
The control circuit provides fast control signals, supplemented by appropriate advance air supply and delayed gas cut-off time, which is very suitable for high-speed spot welding and intermittent welding
Equipped with a high-quality wire feeding mechanism, the wire feeding is smooth and the wire feeding speed can reach 28m/min, improving welding efficiency
The operator can infinitely adjust the arc characteristics from "hard" to "soft" to meet different operating habits
When overloaded, the fan stalls, malfunctions, or there is abnormal overheating inside the power supply, the output stops, automatic protection is provided, and the possibility of accidental damage to the power supply is reduced
To improve the convenience of handling and operation, and to improve the more scientific structure, the volume is smaller and the weight is lighter compared to the previous generation products
Product application
Mainly used for full position welding of low-carbon steel components with a thickness of 0.8-6mm, such as automobiles, motorcycles, steel furniture, filing cabinets, anti-theft doors, and protective fences
Suitable for solid wire with diameters of 0.8 and 1.0
Split type NB-250/300B1 is suitable for places with large working areas
