What idiocy.

Howdy Nick,
I am not sure I understand your statement, could you please elaborate?
Thanks kindly.

Oh man, someone pointed me to the exact gadget I need.

Welds 60" on a charge, which is more than enough for cobbling hasty repairs.
When the little batteries degrade from the abuse, I will happily switch to

Thanks to all for the help!
