Question

which pac torch component provides a path for the electricity from the power source, generates the cutting arc, and is made of copper with a hafnium insert?

a
f
b
d
e
c

Explanation:

Identify the function and material of the component

The question asks for the Plasma Arc Cutting (PAC) torch component that:

1. Provides a path for electricity from the power source.
2. Generates the cutting arc.
3. Is made of copper with a hafnium insert.

Using our knowledge of Plasma Torch Consumables, the component that carries the negative charge from the power source and has a high-melting-point insert (like hafnium for air/oxygen cutting or tungsten for nitrogen/argon cutting) to emit the arc is the electrode.

Match the component to the diagram labels

Let's identify the labeled parts of the exploded PAC torch diagram:

• A: Shield / Shield Cap
• B: Retaining Cup / Nozzle Shield Cap
• C: Cutting Tip / Nozzle
• D: Electrode (made of copper with a hafnium insert at the tip)
• E: Swirl Ring / Gas Distributor
• F: Torch Body / Handle

Therefore, component D is the electrode.
