Question: A welder is troubleshooting a plasma cutting torch that is consistently producing cuts with severe dross at the bottom edge and a noticeably wide, rough kerf. The machine's pressure gauge indicates the air pressure is within the recommended range. What initial corrective action should the welder consider?
Answer options:
- Increase the cutting speed ✅ Replace the nozzle and electrode
- Decrease the amperage setting
- Increase the stand-off distance
Correct answer: Replace the nozzle and electrode
Explanation: Severe dross and a wide, rough kerf, even with proper air pressure, are strong indicators of consumables (nozzle and electrode) that are worn out. Worn consumables cause the plasma arc to become less constricted and diffused, leading to poor cut quality.
