In PAC system setup, what is the first action to perform?

• A. Power on
• B. Set correct amps and air pressure
• C. Connect ground to work piece
• D. Line up the torch to the cutlines and pull trigger

Answer: (A)

Turning on the PAC system first is essential because it powers the control electronics, safety interlocks, and the air/arc systems so you can actually adjust settings and test the setup. Without power, you can’t reliably verify that the machine is ready, nor can you safely or accurately set the amps and air pressure, ground the workpiece, or align the torch. Once it’s powered up, you can dial in the correct amperage and air pressure for the material, attach the ground to complete the circuit, line up the torch with the cut line, and then pull the trigger to start cutting. The ground is only meaningful once the system is energized and the circuit is ready to flow through the workpiece.
