Detailed Information
Gas metal arc welding (GMAW)
This 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.

Frequently Asked Questions
What is the difference between MIG and MAG welding?
MIG (Metal Inert Gas) welding utilizes inert gases like argon or helium for shielding, while MAG (Metal Active Gas) welding uses mixed active gases such as argon-carbon dioxide and argon-oxygen to active specific conditions in the weld pool.
What are the main benefits of the soft-switch IGBT inverter technology?
The soft-switch IGBT inverter technology ensures higher efficiency, less welding spatter, and more aesthetically pleasing welding seams, while offering reliable protection against overvoltage and current issues.
What are the electrical requirements for installing these welding machines?
The machines require an input voltage of 380VAC±10% (50/60Hz), an input cable of ≥6mm² (length ≤3m), a 63A power switch, and an output cable of ≥50mm² (length ≤20m).
What is the difference between the NBC-350A and NBC-500A models?
The NBC-350A has a rated input power of 15.3Kva and an output range of 350A/32V, whereas the NBC-500A offers a higher input power of 22.8Kva and a rated output of 500A/36.4V for heavier-duty operations.
What standard accessories are provided with the purchase?
Each unit comes standard with 1x Electrode Holder, 1x Ground Clamp, 1x Welding Mask, and 1x Brush/Hammer to help you get started immediately.
Can these welding machines be used in harsh environments?
Yes, key parts of the machines feature a three-proof design (dust, moisture, and corrosion protection) making them highly stable and reliable in various harsh industrial environments.
