Question

what components are required for a pac system? (select all that apply.)

work clamp and lead
supply of compressed air or nitrogen
plasma arc cutting power source
additional air filter
either a hand held or a machine-style torch

Explanation:

Identify core PAC system requirements

A Plasma Arc Cutting (PAC) system requires several essential components to complete the electrical circuit and deliver the high-velocity gas jet. These include a power source, a torch, a gas supply, and a work clamp with its lead to complete the electrical circuit.

Analyze each option

• Work clamp and lead: Required to complete the electrical circuit between the power source and the workpiece.
• Supply of compressed air or nitrogen: Required as the plasma gas and shielding gas to create the cutting arc.
• Plasma Arc Cutting power source: Required to provide the constant direct current (DC) power needed to sustain the plasma arc.
• Additional air filter: While highly recommended to remove moisture and oil from the air supply to extend consumable life, it is an auxiliary accessory rather than a fundamental system component required to make the system function.
• Either a hand held or a machine-style torch: Required to hold the consumables, direct the gas flow, and initiate the arc.

Select all matching components

The fundamental components required to form a functional PAC system are the work clamp and lead, the gas supply (compressed air or nitrogen), the power source, and the torch.

Answer:

• Work clamp and lead (Correct answer)
• Supply of compressed air or nitrogen (Correct answer)
• Plasma Arc Cutting power source (Correct answer)
• Additional air filter
• Either a hand held or a machine-style torch (Correct answer)
