Well done :-)

46V i thought it would be lower than that

cool, i love welding

Remember we are talking about STICK welding here, not shielded mig welding. It takes a lot of energy to burn up a 1/8" thick welding rod in a constant stable arc. Please just go try this. You won't get shit for an arc with a 1/8" 6011rod with 3 batteries wired in parallel...promise.

Definitions: Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts).
The AMPere, in practice often shortened to amp, (symbol: A) is a unit of electric current, or amount of electric charge per unit time, in coulombs per second.

I'm going to try and do a new video this weekend in the garage where I actually show you guys how hooking up the batteries and the power available for welding. It'll make more sense when you see it in a controlled environment.

i'm guess its going to fuck the batterys up pretty fast but its a awesome idea

@sasop117 Doesn't hurt the batteries at all. The arc rod provides enough resistance to keep the batteries from discharding too fast. Go check out my other video on this subject where I I show before and after voltage readings across the batteries. Barely drops off the volts at all. In order to kill the batteries you either need to drain them all the way down (would take a LOT of welding) or you would need to discharge rapidly (ground out with a HUGE wire or path to ground.)
