AG Mechanics CDE Practice Exam

When welding, the operator sees by

1. light from the arc

2. reflected light

3. daylight conditions

4. artificial lighting

The correct answer is: light from the arc

When welding, the operator sees by the light from the arc. This is the correct answer because the extremely bright light produced by the welding arc provides the necessary illumination for the welder to see the workpiece clearly and accurately. The intense light emitted by the arc allows the welder to observe the welding process, maintain proper alignment, and ensure the quality of the weld. Reflecting light, daylight conditions, and artificial lighting are not suitable sources of illumination for welding. Welding requires a high-intensity light source to provide sufficient visibility and clarity during the welding process, which is effectively provided by the light from the arc.
