Heavy Industry 350A MIG IGBT Module 500A Welding Machine from China Suppliers - Factory Direct Gas Shielded Solution
Detailed Information
Gas metal arc welding (GMAW/MIG), also known as wire welding, is a commonly used welding process. It is a process that forms an electric arc between the metal and the wire electrode to transmit heat to the metal pieces, and the parts achieve a bond permanently through melting and fusing.
GMAW welding is widely used in all kinds of industries that need welding manufacturing due to its higher cost-performance --- lower welding equipment acquisition expenses, higher welding efficiency, shorter welding work hours, and so on. It has many variables, so it can weld multiple welding materials and meet various welding needs.
Main Features
- All welding machines use new electronic components.
- Soft switch IGBT inverter technology, less welding spatter and beautiful welding seams.
- Complete undervoltage, overvoltage and current protection, safe and reliable.
- Accurate digital display of current and voltage preset, easy and intuitive operation.
- High pressure and slow wire feeding to start the arc, the arc will not burst the wire, and the arc will be closed to remove small balls.
- Constant voltage output characteristics, CO2 welding, one machine for multiple purposes.
- With self-locking/non-self-locking mode, greatly reducing operating intensity.
- Optional extended control cable, suitable for welding operations in narrow and high locations.
- Humanized, beautiful appearance design, more convenient to operate.

Frequently Asked Questions
What is Gas Metal Arc Welding (GMAW/MIG)?
Gas metal arc welding (GMAW/MIG) is a welding process that forms an electric arc between the metal and a wire electrode. This arc transmits heat to melt and fuse the metal pieces together, creating a permanent bond.
What are the primary benefits of using the NBC-350 and NBC-500 welding machines?
Both models utilize advanced soft-switch IGBT inverter technology to minimize welding spatter and deliver clean, beautiful welding seams. They also feature full electrical protections (undervoltage, overvoltage, current) and precise digital displays for easy operations.
What are the power requirements for installing these welding machines?
The machines require an input voltage of 380VAC±10% at 50/60Hz. Standard installation requires an input cable of ≥6.0mm², a 63A power switch, and an output cable of 50mm².
What standard accessories come included with the package?
Each unit comes standard with one electrode holder, one ground clamp, one welding mask, and a brush/hammer tool.
What optional accessories can be purchased for these models?
You can optionally equip the machines with specialized welding helmets, welding gloves, high-quality E6013 electrodes, or a Lift TIG torch to extend the machine's capabilities.
What environmental conditions are recommended for operation?
The machine operates best in ambient temperatures between -10℃ and +40℃. Ensure that the air inlet and outlet are completely unblocked, avoid exposing the machine to direct sunlight, and protect it from excessive dust.
