Single-Tube IGBT Inverter Half-Automatic Gas Shield Welding Machine

Models:
NBC-200GS/NBC-250GS/NBC-250F/NBC-280G/NBC-280GF/NBC-350F/NBC-320GF
Features and functions:
1. Small size, light weight, the weight of medium transformer is much lighter than traditional arc welding power transformer; the weight of the total machine is only 1/5 to 1/10 of traditional arc welding power. The size of the total machine is only 1/3 of traditional arc welding power.
2. High efficiency and energy saving: the power efficiency can reach 85%, the power factor can reach 0.93, can save electricity more than 1/3 than traditional arc welding power;
3. Digital show of welding current and voltage;
4. Current and voltage is continuously adjustable with wide range;
5. The shape of back welding is beautiful;
6. Adopt constant speed wire feeding circuit, can feed wire stably within the whole current range;
7. Welding process is quite stable, and welding shape is beautiful;
8. Internally install unique electronics reactor, can precisely control the e process of short-circuit transition and mixture transition. Can adjust the electronics reactor to get required arc stiffness.
