Good lord, you're going to school for welding and in 28 months they have not taught you to properly set a mig?
Here's the short version:
Wire feed speed (WFS) is your amperage. The faster it comes out, the more amperage it takes to burn off.
Volts get dialed up to make it weld properly.
Not enough volts give a tall ropey, cold looking weld.
Proper voltage widens and flattens the puddle so it wets out properly.
Too much voltage widens and flattens too much with lots of spatter.
Properly balancing amps (WFS) and voltage gives the nicely wetted out puddle you are looking for.
Btw, the shielding gas is in cubic feet per hour, CFH.
Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~
