contractors doing work around the Neuc. Plant and one day it was to repair a fence post that had been broken by a truck. He pulled his work truck right up to the new post so the bumper was touching, got out and plugged his welding cable into a socket he had installed under the hood. He pulled out a control cable to the throttle to get his desired RPM's and started welding. I didn't get a look under his hood but I suppose it was hooked up to his alternator in some fashion. Pretty neat.
