What kind of car battery charger gives you 200A?
You should use welding rods, and like steve' said without regulation you've little control over what it does.

Ah, a starter too. I'm thinking that it wouldn't give you 200A for long. That is you'd spend a lot of time waiting for it to cool down.

Yep. Look at the manual for what its rated duty cycle is at that power level.

Why bother with the carbon rod ? It will weld (DC) directly. Not sure how well it will work, because the regulation is usually non-existent. Try it.
