I haven't watched the video, but I have done this kind of welding a lot in the past.
Three car batteries gives you a lot of heat. Car batteries are made to dump a lot of amperage all at once, so you get the cranking amps that you need to start the car. When they dump this amperage into a welding arc, they can be extremely hot - way more than you would want for welding - enough to make the whole rod smoke.
Most of this kind of welding that I did was done with 2 car batteries. If you had deep-cycle batteries, you could do your welding much better - far less heat.
Be real careful to not ground yourself. Three car batteries is 36 volts when connected in series. Accidentally place yourself into the circuit, and you will fry... especially if you are wet from sweating.
