Metal Inert Gas. A form of gas shielded arc welding that consists of a gun which feeds metal wire into an arc shielded by an inert gas or gas mixture. Produces high quality welds compared to SMAW (stick welding) but not as good as TIG welds. Also, like TIG, MIG cannot be used in an environment with heavy winds as this dissipates the shielding gas.The exception to this rule is if flux core wire is used, then little or no shielding gas is needed.
Many steel and aluminum bicycle frames are MIG welded.

Nickname for "Miguel". Totally Mexican, likely crazy, and 100% badass. Crafty, slightly psychotic, and definitely not someone you want to get in a fight with. He can get a big head sometimes, but really, he's a lot better than he gives himself credit for. He's tough as iron on the outside, but he has his soft spots inside. For instance, when it comes to chivalry, he's definitely old-school. In a good way. Migs would beat the crap out of anyone who picked on the innocent or defenseless. Or a chick. Oh God... don't even go there.
Migs: great opponent, greater ally, greatest brother.
