Question

uses ionized gas to cut through metal
uses a carbon electrode and compressed air to remove metal
not used for cutting, but for joining metal
uses oxygen and fuel gas to cut through metal
a. air carbon arc cutting (cac - a)
b. gas metal arc welding (gmaw)
c. oxy - fuel cutting
d. plasma arc cutting (pac)

Explanation:

The question requires matching metalworking processes to their descriptions. Key details:

• Plasma Arc Cutting (PAC) uses ionized gas (plasma) to cut metal.
• Air Carbon Arc Cutting (CAC-A) uses a carbon electrode and compressed air for metal removal.
• Gas Metal Arc Welding (GMAW) is a joining process, not cutting.
• Oxy-Fuel Cutting uses oxygen and fuel gas to cut metal.

Answer:

uses ionized gas to cut through metal - d. Plasma Arc Cutting (PAC)
uses a carbon electrode and compressed air to remove metal - a. Air Carbon Arc Cutting (CAC-A)
not used for cutting, but for joining metal - b. Gas Metal Arc Welding (GMAW)
uses oxygen and fuel gas to cut through metal - c. Oxy-Fuel Cutting
