Red Seal Welding Practice Exam

In PAC, the arc is:

Transferred to the workpiece directly Not transferred to the workpiece Only used in non-contact mode Used without an electrode

Correct Answer:

Transferred to the workpiece directly

Explanation:

PAC (Plasma Arc Cutting) is a cutting process where the plasma arc is used to melt the material being cut and then blown away with a gas flow to create a cut. In this process, the arc is transferred to the workpiece directly, meaning that the plasma arc actually makes contact with the material being cut. This is what makes option A the correct answer. Option B is incorrect because the arc is indeed transferred to the workpiece. Option C is incorrect because PAC can be done in both contact and non-contact modes. Option D is incorrect because an electrode is necessary for the plasma arc to form.
