So I have been welding for close to 45 years. I also do not have a gas powered welder, as all my welding is done in my shop / garage. While doing up my truck I added the 24V slave receptacle so I can fire up my military gen-set. My guess is with two 12 V batteries in series I should get at least 90 amps DC at the electrode. 3/32" 6010 should run fine for a quick and short 1" bead. The reason I ask is I need to tack on a chain up at our skeet range on the entrance gate. Anyone tried this?

Hi Wayne,

Sure it will work. Folks have been welding up their stuff after crashing around off road just to get home. Check this link out:

Thanks for the link. I thought it should work, now all I need is to get a male plug for my slave and attach some cable. BTW, no need for goggles. Just a welding shields 10+ shade lens, some duct tape and a piece of cardboard. I had to make welds on pipe so close to walls that a shield wouldn't fit.

I used the M37 battery method years ago to repair a broken hood hinge while it was still bolted to the truck, worked great using 3/32" 6011, only ran a couple short beads and that did not hurt the batteries at all. No computers back then so no one to ask, just thought it up and did it.

A couple of years ago I welded one of my concrete saws back together using an Ez-Go golf Cart, some jumper cables, and a piece of steel wire used for a cardboard baler. It was Sunday afternoon on a holiday weekend, I was 2 hours from my shop, and I had a job to ge done. It wasn't too pretty, but it got the saw running again, and got me through the job. BTW It got fixed right when I got back to my shop.
