Question

question 8
what is arc length?
○ the resistance of the flow of current
○ the distance between the electrode and the electrode holder
○ the distance between the electrode and the weld puddle
○ the size of the weld puddle

Explanation:

To determine the correct answer, we analyze each option:

• "the resistance of the flow of current" refers to electrical resistance, not arc length.
• "the distance between the electrode and the electrode holder" is not related to arc length (this is about the electrode's connection to the holder).
• "the distance between the electrode and the weld puddle" is the definition of arc length in Shielded Metal Arc Welding (SMAW).
• "the size of the weld puddle" describes the weld puddle's dimensions, not arc length.

Answer:

C. the distance between the electrode and the weld puddle
