How To Get Your MIG Welding Certification

Do you think you would prefer learning a more automated welding process more than the manual procedures like TIG welding? Consider MIG welding. Most commonly used in fabrication shops with higher production requirements, MIG welding uses a current similar to a car battery. The voltage can be controlled and adjusted.

What Is MIG Welding?

MIG welding requires electricity to produce heat, an electrode to fill the joint, and shielding gas to protect the weld from the air. Differentiating MIG welding from TIG welding is its power source and settings. MIG welding uses voltage when setting the machine. TIG and arc welding machines use amperage, or “constant amperage power supply,” to set the machine.

MIG welding is unlike other welding processes, due to the standard voltage and polarity type that it uses while the current flows in one direction from negative to positive.
