tig filler wire of stainless if you will use as is.. more common steel filler wire better if overlaying with a brass fillet..
Or so I am told..
Most people making custom lugs use a torch and brass to make them, not TIG. TIG welds are much harder to clean up than brass filler. Some folks who have TIG and torch set ups may put a few tack welds to hold the pieces for brazing, but not weld up the whole lug junction.
And everyone else that doesn't even have an expensive TIG welder certainly isn't going to get one just to bi-lam some lugs.
