Answer

D) Nitrogen is only supplied in an additional tank. Explanation 1. Analyze Option A Nitrogen can act as a shielding gas, reducing contaminants and smoke. 2. Analyze Option B Compressed nitrogen is used to displace oxygen in the weld area. 3. Analyze Option C Heated nitrogen melts materials together during welding. 4. Analyze Option D Nitrogen can be supplied in various ways, not only in an additional tank.
