If the voltage and wire feed speed are not changed but a larger wire size is used, the _________.
A) amperage would automatically go up
B) electrode would short out to the weld because more amps are needed for the larger wire size
C) voltage would decrease because the larger wire would have less resistance.
D) voltage would decrease because the larger wire would have less resistance

Question

Quizplus · Accepted Answer

Using a larger wire size while keeping the voltage and wire feed speed constant increases the amperage because the larger wire requires more current to maintain the same welding conditions.
