Battery welding...what did I do wrong?

[bnate]

Looking to do some tack welding on a cheapy Bestop box, so that I can take it to someone to weld up properly. It's 16 guage steel. I linked up the batteries like this article....

and the middle battery positive post just about cooked off when I first began to do the first weld.

what did I do wrong?

any advice?

As long as you wired all the batteries in series there shouldn't be any problem.

Bad battery?

You either did not have it tight or you have it backwards. If the cables were loose it will melt it also. It will ark trying to bridge the gaps around the post. I did the same thing years ago and it melted the cable between the batteries. Oh yeah it fried the battery too so lucky i had just bought it from Walmart. guess what i did...................

Come to think of it, it was loose. THAT'S WHAT HAPPENED....What I dope I am....should have known.

Another quick question, are all top posts screw off/threaded to replace??

I see from the autoparts store that they have threaded top posts. I guess at this point the battery can't get much worse if I try to remove the post....
