Question: When setting up a GMAW machine, what effect does increasing the wire feed speed typically have?
Answer options: ✅ Increases welding current
- Decreases welding current
- Increases arc voltage
- Decreases shielding gas flow
Correct answer: Increases welding current
Explanation: In GMAW, higher wire feed speed means more wire is fed into the arc per unit of time. This requires more current to melt the wire, thus increasing the welding current.
