    Yeah, I'd like to know more about it. You could use this to weld bandsaw blades together or make quick bends in steel without having to fire up a torch or forge.

    No idea on current or any further details; found 'er on the internet. What usually happens here is that someone with more knowledge of this shows up in these threads and posts more info.

    I suppose he knows what he’s doing, but that looks extremely dangerous.

    This pales in comparison to what else he gets up to. I've been a subscriber of his for years. He or youtube took down some of his vids. There aren't nearly as many there now and nothing in the past year is still up.

    I was a truck mechanic when I was in the Marines, and I have seen this more than once when someone would be working on a battery box in one of our 5 ton trucks. About 200A running through a 1/2" wrench. It would take on that lovely shade of red, and hopefully someone would notice before the battery decided to grenade itself spraying everything and everyone with acid.

    I had to remake a lot of battery posts in a motor pool welding shop of a driver training brigade. the posts would get melted off usually due to trainees leaving the cables loose or shorting a wrench across the posts.
    I would saw off the posts then drill in about half an inch then thread to 3/8 16 using a tap that ws ground under size heat up a brass bolt and tighten in to the hole then use a funnel with a post shaped end on it melt some lead and pour over the still hot brass bolt.. Sometimes if the post wasn't all tht bad I would just clean it with some muratic acid and a stainless steel brush then pour lead to build up the post Yu could do a lot of things to those old tar case 100 amp 12v foot square batteries
