MIG
MIG stands for Metal Inert Gas Welding or as named by American Welding Society, Gas Metal Arc Welding (GMAW). To not overcomplicate things, many people just refer to it as wire welding.
Wire welding (aka MIG and GMAW) was first invented in 1940’s. Fast-forward 70 years and the general principles are very much the same. GMAW uses a DC current to create an arc of electricity between the wire electrode and the metals being welded, thus fusing them together.
Because the wire is continuously fed through the welding lead, welders even refer to it as “hot glue gun”. As the previous reference indicates, wire welding is considered to be as easy as using a hot glue gun, which makes MIG the easiest welding method to learn as a beginner.
Although it is considered to be the easiest method to learn, there are still plenty of things you should know if you are planning to learn the MIG/GMAW process, and this is the right place to start. In this section, you are going to find out most of the essential things you need to know, from the best welders on the market, to how you should set up your MIG welding machine, to best practices on how to improve your weld quality so it looks truly professional.
