not sure if this is in the right category but here we go.
I have a ****** old isuzu i wanna weld a rollcage on to it.. nothing pro, just practice.
What do i need to do before i start welding on the chassis?
disconnect battery im assuming but what about the gas tank?
are you supposed to drain the gas tank every time you weld or is the spot your working on the only hot spot(electrically)?
current takes the shortest path so i don't see why it would fry anything so someone answer my question. Thanks
