Cheap Welding for Punks

Step 5 Solar Welder

Here's my Solar Powered Welder project.
Pretty much any alternative energy project will include something that will make a fine welder.
If you're living in an off-grid house with a battery bank, you've got the most powerful welder ever made!

just wondering, but how do you adjust your voltage?

You can clamp to a different place on the battery pack. These are 6 volt batteries, so that lets you choose 12,18,24,30, or 36 volts.

good idea. health and safety wise, i have a criticism to make, its not very possible there but you shouldnt weld facing the wind, your back should be turned to the source of the wind. secondly, you need some more practice before you make anything that will bear any significant weight. i noticed that your welding isnt too god, and im sure if you hit some of your work with a hammer a few times, the weld would crack. i did a level one performing engineering operations (welding, machining, oxyacetelene welding, etc) and passed with flying colours (just to let you know lol) by no means intending to brag, but i thought i would give you a couple pointers. to produce a solid weld, by conventional welding machine anyway, with rod welding the gap from tip of rod to workpiece should be anywhere from 2 - 4 millimetres.
