This approach worked very well for me. I made a copper heat transfer bar from an 100amp electrical dist. panel copper buzz bar. once cut to length you can drill or machine a flat bottom hole and epoxy a rare earth magnet and the backer heat bar will hold itself in place behind the area being welded.
