Question

which pac shield insulates the electrode and protects it from spatter?

d
a
f
e
b
c

Explanation:

Identify the components of the plasma arc cutting (PAC) torch

In a standard plasma arc cutting (PAC) torch, the consumable parts are arranged in a specific sequence. Let's identify each labeled component from left to right:

• A is the Shield (or drag shield), which is the outermost component. It protects the other consumables from spatter and insulates them.
• B is the Shield Cup (or retaining cup), which holds the nozzle and shield in place.
• C is the Nozzle (or tip), which constricts the plasma arc.
• D is the Electrode, which carries the current and emits the arc.
• E is the Swirl Ring (or gas distributor), which swirls the gas to create a vortex.
• F is the Torch Body (or handle).

Analyze the function of the shield

Using the Plasma Torch Consumables knowledge point, we know that the outermost component, the Shield (A), is designed to insulate the inner components (such as the nozzle and electrode) and protect them from molten metal spatter during the cutting process. It also allows the operator to drag the torch directly on the workpiece without short-circuiting. Therefore, component A is the correct answer.

Answer:

• D
• A (Correct answer)
• F
• E
• B
• C
