I need to rejoin an antique stove base. It's 1/8" thick, maybe 3/16"in spots. The last time I tried to tig antique thin cast like this itcracked just from pre-heating cautiously! I'm considering brazing itto lower the heat input. I wouldn't be opposed to taking a chancewith TIG again though. The only rod I have is 308L, 309L and weldmold880, which I think is 312 ss. Oh, I also have silicone bronze filler. The bronze color of brazing rod, or silver ss shouldn't be a problem.So please chime in. TIG or braze?Thanks,Ed
