instead of allowing them to rise to higher levels that could do some
harm.

Actually, following that logic, you should turn everything on--radio,
ignition, lights, global navigator, etc. Otherwise, the 12v clamp isn't
there.

Yeah, I was thinking the same thing.

The only thing I would expect to be protected by disconnecting the
battery is the battery.

And it will carry more current without harm than most welders will put
out.
