Final answer:

In MIG welding, the wire feed speed determines the heat input, with higher speeds adding more material and increasing heat.


Explanation:

The parameter that controls the heat input in MIG welding is A) Wire feed speed. Adjusting the wire feed speed regulates the amount of filler material being added to the weld, consequently affecting the heat input.

For example, a higher wire feed speed results in more material added to the weld, increasing heat input.

Therefore, the wire feed speed plays a crucial role in controlling the heat input in MIG welding.
