Our NBC Series Welding Systems Help Major Steel Structure Company with Efficiency and Reliability
We are proud to share that our NBC series gas metal arc welding (GMAW) systems are now used by a major steel structure company. These systems show great performance in large fabrication jobs. Real photos from their site prove that our welding solutions are reliable and advanced.




The company chose our NBC welders because they are built for tough industrial work. Here are the main technical benefits that make these systems right for heavy use:
✅ Advanced IGBT Inverter Technology
Gives stable arc performance and greatly lowers energy use. Improves operation reliability and allows precise control of welding settings.
✅ Industrial-Grade Duty Cycle
Made for non-stop work in hard conditions. Keeps 100% duty cycle in the NBC-350 model, good for continuous production.
✅ Proven High Performance
Creates clean, low-spatter welds with deep melting and smooth look. Strong dynamic response allows easy arc start and steady welding on different materials.
✅ Energy Efficiency (Grade I)
High efficiency (≥85%) and power factor (>0.95) cut electricity bills and support green operations.
Features Made for Heavy Industry
The NBC series can weld low-carbon steel, low-alloy steel, and other metals with solid or flux-cored wires (Φ0.8–1.6mm). Its mix of static and dynamic traits provides:
Strong arc adjustmentHigh melting efficiency (4 times faster than manual welding) Very little distortionNice-looking welds
Good for uses in:
🏗️ Construction machinery and steel structures
⚓ Shipbuilding and car making
🔧 Boilers, bridges, railways, and petrochemical jobs
