Detailed Information
What Is the Importance of MIG Welding in Manufacturing?
MIG welding is valuable because it is fast, creates a strong joint, and can weld thick metal pieces together. MIG welding is also simple. Since it’s easy for first-time and experienced welders alike, there’s usually no shortage of MIG operators in the workforce.
What Is the Primary Purpose of MIG Welding?
MIG welding is used to join metal parts together. It functions to join steel, stainless steel, cast iron, and aluminum. MIG welding is used on sheet metal, pressure vessels, steel structures, pipelines, and automotive parts.
How Does MIG Welding Work?
MIG welding works by feeding a metal wire through a gun which conducts electricity from the welding machine. It generates an arc with the target material in order to melt both the metal wire and part of the joint and form a metal bond. As the wire is fed through and a molten weld pool is created, the weld is protected by a shielding gas. The shielding gas protects the weld from contaminants in the atmosphere.
Main Features
- All welding machines use new electronic components.
- IGBT inverter technology, less welding spatter and beautiful welding seams.
- Can weld aluminum, aluminum alloys, carbon steel, stainless steel and other metals.
- Accurate digital display of current and voltage preset, easy and intuitive operation.
- Dual voltage input 220V/380V automatic conversion.
- Gas shielded welding/manual welding/scratched argon arc welding, multiple functions.
- 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.
