It is very important that the welding current does not return through a bearing, because it can cause pitting, which will lead to bearing failure soon after. The welding current does not have a path to the computer, so don't bother to disconnect the battery. Disconnecting the battery could cause the radio antitheft setup to kick in, which can be a PITA.
