How can you verify that the welding machine is delivering the set voltage and current?

• A. Rely on the operator's feel.
• B. Visual inspection only.
• C. It's not necessary to verify.
• D. Use the machine gauges/meters and perform a test weld to confirm the actual settings match the programmed values.

Answer: (D)

The main idea here is to confirm that the machine’s programmed voltage and current are actually being delivered during welding. The best way to do that is to use the built-in gauges or meters to read the output and then verify with a test weld. The meters give you numerical evidence of what the machine is putting out, so you can compare the measured voltage and current to the values you programmed. But numbers alone don’t tell the whole story, which is where a test weld comes in: running a short weld on a scrap piece lets you judge the arc characteristics, bead appearance, penetration, and heat input under real conditions. If the readings and the test weld don’t match the expected results, you can adjust the programmed values and recheck.

Relying on how the operator feels isn’t reliable because arc length and heat feel can vary with technique and conditions. Visual inspection alone won’t confirm the actual electrical output or whether the settings will produce the desired weld quality. And skipping verification isn’t correct because ensuring the machine performs to the programmed values is essential for consistency and quality.
