Works excellent as a backer for plug or butt welding. I produced very good plug welds as a beginner after using these practicing for about 10 min. The magnets suck though. They lost their hold as soon as the copper got warmed up. I just took another magnet & backed them up or would clamp them in place if needed. A bit pricey though for just a couple of peices of flat copper. Not much to manufacture after all. Certainly the cost isn't in the magnets used. Only negs are price & magnets.

I had the magnets pull out after getting the copper hot from welding too and the magnets seemed to have lost their magnetism after that also. The copper is heavy and works well to weld against but as has been stated, they don't bend and I find thier use limited. I bought 2 large, flat magnets to hold the plates in place and have also used clamps to hold them. I will be purchasing the flexible wedges for use on fender repair for better contour conformity.

These consist of a nice piece of heavy copper. They works well on very flat surfaces only. It will not conform to surfaces that are not flat so magnets will not adhere to the workpiece. The magnets are held into hole in the copper by a pressure fit. I got mine so hot that he copper expanded and some of the magnets fell out. When I tried to press them back in the magnets broke into pieces.
