Hello Mike,
I am glad that you consider the block to be in rough condition. I bought the brass block to use with plug welding rust holes in automotive sheet metal. Am I right in thinking that either brass or copper could be used as a backing when welding up rust holes in sheet metal? I just had a look online and there are some brands of plug welding pliers that feature a copper-plate top jaw.
Of the two options copper or brass - which one is the best option for carrying out plug welds in sheetmetal? Or the two equal to the job?
Kind regards
Lionel
