One other quick point... on a MIG welder, the wire speed is actually your "HEAT" and voltage serves as pressure, or "puddle fluidity" On thick materials, the wire speed goes up WITH the voltage (ideally, they are a 5-6/1 ratio ie 120Amps, 20 Volts) for a decent weld on 3/16" plate, and vice-versa for thin steel. On machines with no actual numerical values, if you really want to be picky, use an ammeter and voltmeter to calibrate them.
