Introduction: Spot Welder

This is very basic homemade spot welder. Tested! Works ok! :)

Notice the way electrodes are fixed to the wire. It is most basic way and takes some filing (sharpening electrode tips) - can burn your fingers during operation- gloves needed!! Next time ill try to make a armature for proper electrodes alignment.

Yeah... do a step-by-step, as this looks like the simplest version I've seen.

Are you making contact then applying power or applying power then making contact ? I think the former would serve you better and you would avoid arcing.

First I put one of electrodes on the top of the battery and then I turn the power on. Finally i put the other electrode on and I press on. Takes some practise and I didnt have much time to play with it for long but I will let you know as soon as I will figure out easiest way. I am sure it cn do the job - I did a sample on batterry.
