A MIG (Metal Inert Gas) welder is a type of welding machine that uses a wire electrode and an inert shielding gas to fuse two pieces of metal together. The welder feeds a continuous wire electrode through a gun and into the weld pool, where it melts and fuses the metal. The inert gas, such as argon or carbon dioxide, helps to protect the weld pool from contamination and provides a stable arc for welding.
MIG welders are popular for their versatility and ease of use, as they can be used to weld a variety of metals, including steel, aluminum, and stainless steel. They are commonly used in automotive repair, manufacturing, and fabrication, as well as in a variety of other applications. MIG welders are also relatively affordable, making them a popular choice for hobbyists, DIYers, and small shops.
Some of the key features of a MIG welder include adjustable welding speed, adjustable heat control, and the ability to switch between different wire diameters and shielding gases. MIG welders can be operated from a 115V or 220V power source, and come in a range of sizes and power outputs to suit different welding needs.
