If the arc length is too long when stick welding, what sound is heard?

1. booing

2. crackling

3. fizzling

4. hissing

The correct answer is: booing

When stick welding, if the arc length is too long, a "booing" sound is heard. This sound indicates that the distance between the electrode and the workpiece is too far, causing the arc to be unstable. A proper arc length is crucial for a successful welding process, as it affects the quality of the weld and prevents issues such as spatter or lack of penetration. The other options, crackling, fizzling, and hissing, do not accurately describe the sound associated with having a too long arc length in stick welding.
