Almost got hurt today. PSA

Change the plug and then amp clamp it.
Was at my buddy's shop and he was TIG welding. I noticed a funny smell and looks over at the welding area and i see smoke.
I walk over trying not to get arc flash and look around to see if he caught something on fire.

I'm not real clear on what happened next as it all happened real quick.

I think I noticed the cord on his new TIG was melting and why I did this I have no idea. I switched off the machine to keep it from getting fried and went to unplug the welder.
he has a long 50 amp cord running to this machine so I stepped on the cord with my shoe and pulled the plug with my bare hand. And BOOM!
THE CORD EXPLODED, big ball of light and a loud arc noise.....

It exploded about 2 or 3 inches from where I had grabbed it..

This is a 20 amp cord plugged in to a 50 amp cord on a machine that pulls 40 amps....

Why the hell the machine came with a 20 amp cord and plug I have no idea. It clearly stated it pulls 40 amps right on it....


So let's all keep our hands and skin intact and FLIP THE DANG BREAKER before touching malfunctioning electrical components......

Man I got lucky......

I got hit before with 220 welding in the rain when I was a tower monkey and it took me 3 days before I felt ok...

If this had blown up in my hand it would have been all bad....

My bad....
You shut it off first.
I'm guessing the insulation melted and the two legs shorted.
