The title of the video is “Welding Accident” — which I’m guessing is what people who don’t know what things are call anything with a hose that shoots sparks — but what this turns out to be is a cutting torch no-no.
The worker, sitting astride a large diameter pipe that’s held down on one end by a digger shovel, proceeds to Looney Tunes himself a cut. Of course, when the pipe is free to move, it does so, pitching him off and popping all that stored energy in one quick snap, which I’m sure sounded great as the guy hurled through the air.
Not really a smart play here. Know your loads, know the stress, and plan ahead.
