So I am looking for the best way to join .125 Dia stainless wire. I have no welding or brazing equipment as of now and am looking to do this as cheaply as possible. The whole purpose is that I am looking to start building "rolling ball sculptures" (ex. http://www.rollingballsculpture.com/ ) It seems welding or brazing is the preferred method but i have been pricing gas setups and they are a bit more than i had hoped for once you factor in the bottles. I have experience with brazing, mig, tig, and limited stick welding so i am not worried about the learning curve side of things. I guess my one other option would be to put together a home made spot welder as i have seen plans online for several but no sure how well it could end up handling the .125 stainless. Hope someone can help me sort this all out.
