Welding With Batteries - Page 4

 There is a manufacturer, located I believe in California, that sells a
portable MIG gun which runs off two 12 volt batteries connected in
series. It is a nice-looking tool, but I thought it was too expensive
for the limited use I would give it.

buy longest jumper cable you can then get some carbon welding rods and some
brazing rod

hook up jumper cables to batteries then hook up one to what your working on
put carbon rod in claw of the jumper cable and weld away using the brazing
rod to weld or if you just want to cut through just use the carbon welding
rod..

is that cheep enough for you may take some practice but easy enough to do if
your handy at stuff....

Funny you mention that. I "discovered" that technique as a youngster. It's
amazing how hot a carbon rod will get. It was almost as bright as a
purpose-made carbon arc.

 Will that be with regular auto batteries or with deep-cycle ones, or maybe
it doesn't matter if you're just going to use it casually. Any tips on how
heavy the materials can be? As a nerd kid I once made a carbon arc in my
bedroom using rods from flashlight batteries and a clothes-iron as a
ballast, it was fun untill my mother smelled what was going on and busted
me.
