I'm thinking of install a 220v 30amp outlet for a welder (small) but my
main service box has the grounds and neutral hooked to the same block.
Take a look

Because the current is supposed to flow in the neutral, and the
ground is there as a *safety*. I.E. *ALWAYS* at ground, no
matter how the current flows. Think of an open neutral somewhere
in your house. If the ground, which is hooked to appliance
cases, were the same as the neutral, these case would suddenly be
at 120V. ...not good.
Ground is your friend (usually). Neutral is there as a return
for electrons. They're tied together at your entrance panel to
keep the peace. ;-)
