Your going to actually need about 12 car bateries for it to work at 144 volts but link them all together and take a jumper cable atach the black to the negative the ground it at the other end by puting it on a separate piece of metal. Then take the red and put it on the positive end of the battery. Now you need a welding rod and just hold it with the red clamp and start stick welding.

Can a 24V battery charger be use to a 12V car battery?

no. It can overheat the battery, damaging it.Here is a separate answer: I just charged a 12v car battery using a 110v DC Welder set on 10 amps, and putting out 50v. I had to check the battery every 30 minutes for overheating, which it did not. I know this is not recommended as I risk damaging the car's electrical system and the battery, but I was in a pinch.I only charged it for 1.5 hours, and there is a substantial risk that the battery will explode. I disconnected the terminals at the welder to avoid igniting the hydrogen that forms around the battery during the process.Other risks include overcharging the battery because chargers designed for 12v drop to a trickle when the battery is fully charged, avoiding damage to the battery.

What do you do if your hot water pipes freeze?

First you open the a facet to allow any water to flow, or pressure to relive. With a propane type torch heat the pipe until water flows, being careful of the flame not to burn the place down. If you have access to a arc welder, they can also be used, by clamping the stinger and ground to the pipe apart from each other, and turning the welder on. A car battery and jumper cables also will work, hook up as you would the welder, connecting the ground of the battery to the pipe as the last connection. All methods need some sort of care to make sure nothing goes wrong. The battery is the safest, but you only have the charge in the battery to work with.


How can you make a car without a battery move?

If your car has a battery and it's dead, you can call a friend who has some jumper cables. You can hook the jumper cables up to his battery and your car's battery. It should create electricity that will renew your battery. If your car does not have a battery, you would have to push it or get it towed.
