This e-book is for the do-it-yourselfer that wants a very inexpensive but POWERFUL and portable arc welder. It is for someone that may live off the grid or doesn't have 240 volt power to their workshop or the place where the welding needs to be done. It is for someone that wants an easy to build pulser / charger for bringing back to life car batteries that have been thrown out. I even use the pulser for fixing my nicads.
One day I was looking at getting a welder in my small shop. I had a small 30 watt solar panel and a small homemade windmill charging up some golf cart batteries. I figured I could get a small hobby welder for a few hundred dollars but it couldn't weld anything except thin metal. I wanted something much more powerful. I didn't see any reason to waste $400 and then have to buy another machine later. And I couldn't run a big 220 Volt machine because I didn't have the power in the shed.
I looked around the internet and found that some people had done emergency welds just using 2 or 3 car batteries. I knew that an average car battery could easily handle 400 amps for short periods. Imagine 400 amps at 36 volts ( actually it is 12.7 volts times 3). That would be over 15,000 watts of power! I've seen gas powered welding machines that are massive. They produce 400 amps at 36 volts (14,400 watts) and they cost several thousand dollars - used. New, they are over $10,000. They also weighed as much as they cost and had to be towed around. While 3 car batteries only weighed about 120 lbs or so.
This was great because I could put the welder in the back of my truck and weld anywhere. I even bought 3 of those cheapo (12 v - 2 watt) solar panels and put them in series so that they would charge 36 volts. That way they are always charged.
I've even welded 1/2 inch plate steel before and it was no problem!
