Battery Welding: here are some brief instructions on welding with 
batteries. First of all, you need at least two car batteries, but three is 
better. The reason for this is that you need about 36 volts to get a decent 
arc from the weld rod. You must wire the batteries in a series fashion. You 
can use a few sets of jumper cables to do so. The batteries must be as far 
away from the welding as possible! Also cover them with a blanket or tarp 
incase of an explosion.

Three batteries: From the first battery, attach a cable from positive to 
negative of the second battery. Then from the second battery, connect a 
cable from the positive to the negative of the third battery. Now, your 
welding rod cable will go from your positive side on your third battery, 
and the ground cable will come off the negative side of the first battery. 
Your ready to weld now! Be real careful!!!!!!

This will produce 36 volts and about 250 amps.
