China Suppliers Factory Split 350A MIG IGBT Module 500A Gas Shielded Welding Machine for Superior Welding Performance
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.
- 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.
- Three-proof design for key parts, suitable for various harsh environments, with stable and reliable operation.
