Product Description
NBC Series IGBT Soft Switch Inverter CO2 Gas Shielded Welding Machine (NBC-250, 350, 500, 630 IGBT (S))

The NBC series IGBT soft switch inverter CO2 gas shielded welding machine includes several models: 250A, 350A, 500A, and 630A.
This machine adopts advanced domestic logic control IGBT soft switch inverter technology, with minimal IGBT losses and stable output current. By adjusting the spatter knob, it can reduce spattering effectively.
It has the advantages of high weld seam quality, aesthetic appearance, low spatter, low welding cost, high production efficiency, portability, and significant energy savings.
It is suitable for welding low-carbon steel, low-alloy steel, carbon steel, high-quality carbon steel, and other metals.
Main Features:
1. Uses digital display, allowing for precise presetting of voltage and current, making standardized adjustments convenient.
2. High efficiency, minimal no-load losses, and significant energy-saving effects.
3. Utilizes IGBT soft-switch inverter control technology, resulting in low IGBT losses and lower failure rates compared to ordinary inverter welding machines.
4. Adopts waveform control technology, which can achieve excellent welding results by adjusting the inductance level, improving formability, and minimizing spatter.
5. Incorporates passive power factor correction technology, ensuring a high power factor.
6. Equipped with a wire jog function for easy wire threading.
7. Features pre-gas and post-gas functions, effectively protecting the welding area.
8. Offers a slow wire feed arc initiation function, with a high success rate in initiating arcs.
9. Includes a arc-ending function, allowing for continuous adjustment of arc-ending current and voltage.
10. Equipped with FTT (Flat Topping Technology) for effective reduction of balling.
11. Continuously adjustable current and voltage with a wide range of adjustment.
12. High continuous load capacity, suitable for long-duration continuous welding.
13. The NBC(S) models can be used as gas shielded welding machines and also for manual welding and carbon arc air gouging.
