After turning on the PAC system, what is the next step?

• A. Check the fuel level
• B. Set correct amps and air pressure
• C. Place clamps on material
• D. Clean the work area

Answer: (B)

In plasma arc cutting, the immediate setup step is to dial in the operating parameters: the correct amperage and air pressure for the material you’re cutting. Amperage controls the amount of heat and cutting speed, while air pressure stabilizes the plasma jet and helps produce a clean cut. Getting these settings right ensures good cut quality and protects the torch from unnecessary wear or damage. Checking fuel level isn’t applicable here because the system uses compressed air, not fuel. Clamping the work and cleaning the area are important safety and preparation steps, but they come after you’ve set the proper machine parameters and are ready to cut.
