China 350A MIG IGBT Module Welding Machine 500A Gas Shielded Welding Suppliers and Factory with Superior Performance
Detailed Information
Gas metal arc welding (GMAW) is the process of arc welding with a consumable, solid welding wire electrode, covered in shielding gas. Depending on what type of gas you use, the most common GMAW processes are metal inert gas (MIG) and metal active gas (MAG). The MIG process typically uses argon or helium, which are inert gases, for shielding. The MAG process more commonly uses a mixed gas, e.g. argon-carbon dioxide and argon-oxygen, which activates certain conditions in the weld pool. Some machines also support flux cored arc welding (FCAW), which utilises a flux cored wire instead of a solid wire.
ALPHA MIG/MAG welding machines: At ALPHA, we strive to deliver the very best welding performance and user-friendly welding machines across our product line and our gas metal arc welders are a testament to the quality and knowledge we put into every product. Our MIG/MAG welders are in use all over the world, building and servicing great constructions for industries such as manufacturing, offshore, construction, agriculture – but also used to repair cars in the auto business. Our synergic machines make it easy to adjust amps, wire feed speed and the resulting welding speed along with other welding parameters, by the turn of a single knob. You can even control the parameters from the welding gun.
Main Features

Frequently Asked Questions
What is the difference between MIG and MAG welding?
MIG welding utilizes inert gases like argon or helium for shielding. MAG welding uses active gas mixtures, such as argon-carbon dioxide and argon-oxygen, which react with and activate specific conditions in the weld pool.
What are the main advantages of using IGBT inverter technology in your machines?
Our soft-switch IGBT inverter technology ensures higher efficiency, significantly less welding spatter, and produces exceptionally clean and beautiful welding seams.
What safety protection features are built into these welding units?
The machines are equipped with comprehensive protection systems against undervoltage, overvoltage, and overcurrent, ensuring a safe and reliable operating environment.
What are the power requirements and suggested cable specifications for installation?
The system requires an input voltage of 380VAC±10% (50/60Hz) with a 63A power switch. The input cable should be ≥6mm² (length ≤3m) and the output cable should be ≥50mm² (length ≤20m).
Can these welding machines be used in harsh industrial environments?
Yes, key parts feature a specialized three-proof design (protecting against dust, moisture, and corrosion), making them highly stable and reliable for operations in harsh environments.
What standard accessories come included with the machine purchase?
Each unit comes standard with one electrode holder, one ground clamp, a welding mask, and a brush/hammer tool.
