Step 1: Concept
Arc welding uses a high-temperature electric arc to melt and join metals.
Step 2: Meaning
The arc is a continuous spark that occurs when electricity jumps across a small gap in a circuit.
Step 3: Analysis
To complete the electrical circuit, one terminal is connected to the electrode and the other is connected to the metal being welded. When the electrode touches and then slightly pulls away from the metal, the arc forms between them.
Step 4: Conclusion
The arc is created between the electrode and the work piece.
Final Answer: (B)
