If he was using oxy-acetylene, he did not know what he was doing or he was working with welded iron pipe.

NEVER splice, and I mean NEVER splice, LAN cabling. You might have crossover problems and you might not notice the loss in bandwidth until you hit 20MB+ connection speeds and then things get very 'interesting'.
