An arc that is the correct length when stick welding should sound like:

  1. Bacon frying

  2. Buzzing

  3. Crackling fire

  4. Hissing

The correct answer is: Bacon frying

When stick welding, you should listen for a consistent sizzling sound, similar to bacon frying, to indicate a properly set arc and sufficient contact between the electrode and the metal. Option B, buzzing, may indicate an inconsistent arc or incorrect voltage settings. Option C, crackling fire, suggests a fast-moving arc which can cause uneven welds. Option D, hissing, could indicate an arc that is too long or too close to the workpiece, resulting in poor quality welds.
