 Sichuan Morrow Welding Development Co., Ltd., a pioneer in IGBT inverter welding technology, is proud to announce the successful renewal of its ISO 9001:2015 Quality Management System certification as of June 2024.

The world's industry is moving to green and low-carbon work. So, energy efficiency is now a key measure for welding equipment. Sichuan Morrow Welding Development Co., Ltd. ("Morrow Welding") released a technical report. This report shows a new breakthrough. The breakthrough is in IGBT Full-Bridge Soft-Switching Inverter Technology. This IGBT Full-Bridge Soft-Switching technology helps industrial welders use 25% less energy.

In modern industry, welding technology is often called the "Industrial Tailor." Morrow Welding is a top manufacturer of welding power sources in China. Morrow Welding has a strong place in China's heavy industry. Morrow Welding has also worked on big national projects. This is because of its very good IGBT inverter technology.

Morrow Welding Development Co., Ltd. (Morrow Welding), a trusted global supplier of welding power sources for important industries like shipbuilding, oil & gas, and metallurgy, has released a new analysis. This analysis shows how the precise low-current stability of its top welders is changing high-quality, thin-material fabrication. Low current welding is key here.

Morrow Welding is a leading manufacturer of advanced welding power sources. The company provides high-performance and durable welding machines to the global industrial sector. our products serve key heavy industries like steel, shipbuilding, oil and gas, and metallurgy.

Morrow welding machines offer strong advantages. We have excellent dust and EMI shielding. Components are well protected against oxidation and burnout. Advanced Digital Signal Processing (DSP) control technology ensures stable arcs. For example, the Morrow NBC-500 machine can weld with Φ1.2 solid wire at only 70A. The machines also feature superior High-Speed Pulse welding. This sets a high standard for reliability and efficiency.

Our NBC series GMAW systems are used by a major steel structure company. They perform very well in large projects. These welders use advanced IGBT inverter technology. This gives stable arcs, precise control, and saves energy. They have high efficiency (≥85%) and a power factor over 0.95. The NBC-350 model offers 100% duty cycle for continuous work. 

They work with solid or flux-cored wires from Φ0.8–1.6mm. They weld low-carbon and low-alloy steels very well. The welds are clean with little spatter and deep penetration. There is very little distortion. They work four times faster than manual welding. 

These systems range from 350A to 630A. They are built with all-copper transformers and quality parts. They work well in construction, shipbuilding, bridges, and petrochemical jobs. They are strong and reliable for tough environments. 

Sichuan Morrow Welding Development Co., Ltd. achieved remarkable success at the Essen Welding and Cutting Fair 2025, held in Shanghai from June 17th to 20th. The company's next-generation innovations, including triple-wire twin-arc systems, robotic welding solutions, and full-position pipe welding equipment, captured significant industry attention.

In June, Shanghai will become the global focal point for welding technology once again. As the world's largest and highest-standard event in the welding industry, the 2025 Shanghai Essen International Welding Exhibition will commence on June 17th at Shanghai New International Expo Center.
