Hi Tom,
Yes it works great. PV is the perfect set up for welding - it doesn't matter if you short it out. The modules in the youtube are in parallel, not series, and that is how I've done it. We have a power trailer set up for temporary power that works perfectly - it's 9: 195W Suntechs: http://imageevent.com/cotuitsolar/1303publicalbum?p=40 <http://imageevent.com/cotuitsolar/1303publicalbum?p=40&n=1&m=-1&c=3&l=0&w=4 &s=0&z=3> &n=1&m=-1&c=3&l=0&w=4&s=0&z=3 It's about right for 3/32" stick welding under optimum conditions if you're a decent enough welder.

Hello Wrenches, Recently, while working overseas, we were asked by a welder we employed if we could make a "solar welder" for him. So, not wanting to dismiss his request, my initial thought was to eliminate an inverter and welder for cost and efficiency reasons and weld directly from a battery bank. I have done some homework on this and it seems as though it may be feasible. There is a YouTube video of a guy doing this with 3, 12 volt batteries in series. This would be stick welding only and rod of ~ 3/32". There would be some details to work through, but the biggest one seems to be a means to limit current to the electrode. Has anyone attempted this and/or know of a means to limit the current to the rod? Thank you, Tom DeBates Habi-Tek Geneva,IL. 60134
