Question

what is the primary difference between a cutting tip and a welding tip on an oxyfuel torch?
a a cutting tip has a central oxygen jet to blow molten metal away, while a welding tip produces a soft flame for melting and joining.
b a welding tip uses electricity, while a cutting tip uses gas.
c a welding tip is only used with propane, while a cutting tip is only used with acetylene.
d a cutting tip mixes gases inside the torch body, while a welding tip mixes gases in the hoses.

Explanation:

• Option A: Correct. A cutting tip has a central oxygen jet to remove molten metal, and a welding tip produces a soft flame for melting/joining.
• Option B: Incorrect. Both oxyfuel cutting and welding tips use gas (not electricity for oxyfuel welding/cutting).
• Option C: Incorrect. Both can use various fuels (not limited to propane for welding or acetylene for cutting).
• Option D: Incorrect. Gas mixing for oxyfuel tips (both cutting and welding) is typically in the torch body or tip, not as described.

Answer:

A. A cutting tip has a central oxygen jet to blow molten metal away, while a welding tip produces a soft flame for melting and joining.
