Step 3Batteries!
My golf cart has 6 of these 6 volt T-105 size batteries that I bought used from THE GUY WHO MADE THEM!!!
They're in series making 36 volts total. I can clip in anywhere in the chain to get 36,30,24, etc. volts.
The batteries have about 220 Amp-hours capacity, so that means I could weld at 150 amps for more than an hour (consult books printed on paper for the details) without recharging. Plenty good since I'll never have a project with enough metal laid out ahead of time to spend that much time a-welding in a day.
If your batteries aren't as nice as this, don't worry, you can do plenty of welding with three old car batteries in series.
I got these from the guy who made them?
That's right, a family run battery manufacturer right in Sausalito in a little workshop.
It's really amazing, like an old time blacksmith's shop, but high-tech. They can make any size battery.
Alrick, the proprietor, grew up making batteries and he really knows his stuff.
He sells batteries to all the big boats there, and he knows exactly how long every brand of battery lasts in every set of conditions.
Don't bother him about your electric car though, he's been plagued about that sort of thing enough already.

Golf carts use deep cycle batts already.
Just try not to overheat them nor recharge while still hot and everything should be fine.
All batteries eventually wear out.
Sometimes you can revive "dead" lead acids with a little epsom salt.
This make it possible you could "recycle" (more like reuse) discarded batteries you can get for free.
or a welder...
