MIG hand protection tends to fit looser and often have extra padding on the back of the hands. MIG welders typically rest one of their hands on the work surface while bracing the dominant hand during a weld, this padding further protects the non-dominant hand while working. MIG welders gloves are designed to be easily thrown off if it becomes too hot. These attributes may reduce maneuverability for the fingers but MIG welding techniques rely on wrists rather than fine finger movements.  In a nutshell, MIG gloves offer outstanding protection for the entire hand.
