Which statement best describes the relationship between oxy-acetylene welding and electricity, as well as wind sensitivity?

• A. It requires no electricity and is not sensitive to wind or drafts
• B. It requires electricity and is highly wind-sensitive
• C. It requires electricity but is not wind-sensitive
• D. It requires no electricity but is wind-sensitive

Answer: (A)

Oxy-acetylene welding relies on a flame produced by burning acetylene with oxygen, so it does not need electrical power. This makes it different from electric welding processes that require a power supply. In the context of this question, the flame is treated as not wind-sensitive, meaning the process isn’t described as being affected by wind or drafts in terms of its basic setup. So, the description that it requires no electricity and is not wind-sensitive captures how oxy-acetylene welding operates in these terms. Other scenarios would involve electricity or a notable sensitivity to wind, which isn’t part of this description.
