Setting up a welding job, where the work is the positive pole and the electrode is the negative pole for the arc, is known as a/an __________.

Correct Answer: Option C — straight polarity welding circuit

Straight polarity, or electrode negative (DCEN), occurs when the electrode is connected to the negative terminal and the workpiece to the positive terminal. This configuration directs more heat toward the workpiece, which is advantageous for welding thicker materials or when deeper penetration is required during the arc welding process.
