MIG/MAG Welding Machines - Complete Guide to Gas-Shielded Welding
What is MIG/MAG Welding?
MIG (Metal Inert Gas) and MAG (Metal Active Gas) welding are among the most widely used welding types in industry. They use continuous welding wire with shielding gas to protect the weld from oxidation.
Difference Between MIG and MAG
- MIG: Uses inert gas (pure argon) for welding aluminum and stainless steel.
- MAG: Uses active gas (CO2 or argon/CO2 mix) for welding iron and carbon steel.
Advantages of MIG/MAG Welding
- High welding speed increases productivity.
- Clean welding without slag reduces cleanup.
- Easy to learn compared to TIG welding.
- Suitable for different metal thicknesses.
- Can be automated in production lines.
Choosing a MIG/MAG Machine
When choosing a machine, pay attention to amperage capacity (for thicknesses you'll weld), feed type (wire or spool), and Duty Cycle. 200-250 amp machines cover most industrial applications.
Welding Safety Equipment
Auto-darkening welding helmet, leather welding gloves, leather apron, and safety boots are essential when welding. All available at ESCO Engineering Warehouses.
