When welding, what is the primary source of light for the operator?

1. Arc light

2. Overhead lamp

3. Sunlight

4. Torch light

The correct answer is: Arc light

When welding, the primary source of light for the operator is the arc light. The intense light produced by the electric arc during welding provides visibility for the operator to see the weld pool, workpiece, and surrounding area clearly. This illumination is crucial for the welder to ensure accuracy and quality in their work. The other options - overhead lamp, sunlight, and torch light - are not typically the primary light sources for welding. While an overhead lamp can provide additional lighting in the workspace, sunlight is not reliable and may not be sufficient depending on the welding environment, and torch light is used for cutting and heating, not as the primary source of illumination during welding.
