What is the difference between alternating current (AC) and direct current (DC)?

• AC flows in one direction, while DC alternates between negative and positive

• AC alternates between negative and positive, while DC flows in both directions

• AC flows in one direction, while DC flows in both directions

• AC alternates between negative and positive, while DC flows in one direction only

What is DC Electrode Positive in arc welding?

• The percentage of time a machine can be used at a particular amount of current

• A welding defect that occurs when using DC current, allowing a magnetic field to build up around the arc

• Arrangement of direct current arc welding cables and leads in which the electrode is the negative pole

• Arrangement of direct current arc welding cables and leads in which the electrode is the positive pole
