In a constant-voltage GMAW system, increasing wire feed speed will cause voltage to

Explanation:
In a constant-voltage welding power supply, the voltage is held at a set value, while current is allowed to adjust to changing welding conditions. When you increase the wire feed speed, more metal needs to be melted, so the current rises to melt the extra wire. The power source keeps the arc voltage at the pre-set level, so the voltage stays essentially the same. Minor fluctuations could occur if the arc length or other conditions shift, but in steady operation the voltage does not change.
