China Heavy Industry 350A MIG IGBT Module 500A Gas Shielded Welding Machine - Reliable Suppliers & Factory Solutions
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 GMAW/MIG welding?
Gas metal arc welding (GMAW/MIG), also known as wire welding, is a process that forms an electric arc between the metal and the wire electrode to transmit heat, melting and fusing the metal pieces to form a permanent bond.
What are the primary features of the NBC-350 and NBC-500 models?
Both models feature soft switch IGBT inverter technology for less welding spatter, complete undervoltage/overvoltage protection, accurate digital displays, constant voltage output, and self-locking/non-self-locking modes.
What input voltage and switch requirements are needed for installation?
The required input voltage is 380VAC±10%, 50/60Hz. A power switch of 63A and input cables of ≥6.0mm² are recommended for proper operation.
Which welding wire sizes are suggested for these machines?
For the NBC-350 model, the suggested welding wire size is 0.8-1.2mm. For the NBC-500 model, the suggested wire size is 1.0-1.6mm.
What accessories are included in the standard package?
The standard accessories package includes 1x Electrode Holder, 1x Ground Clamp, 1x Welding Mask, and 1x Brush/Hammer. Optional accessories like helmets, gloves, electrodes, and TIG torches can be purchased separately.
What are the recommended environmental conditions for usage?
The machine operates best in ambient temperatures ranging from -10℃ to +40℃. Ensure that the air inlet and outlet are not blocked, avoid direct sunlight exposure, and take measures to prevent dust buildup.
