The voltage settings on a standard MIG welder determine the power used during the MIG welding operation. There is always a necessary balance between voltage and wire feed speed. Especially since the wire feed speed needs to increase as the voltage also
Why is there no amperage control on a MIG welding …
MIG welding power sources have what is known as a ''constant voltage'' output characteristic (Fig. 1). The arc voltage is established by setting the output voltage on the power supply. The power source will then supply sufficient welding current to melt the welding electrode at the rate required to maintain the preset voltage (or relative arc length).
