On this topic ...
My 'muffler guy'--Gary--has done a couple jobs for me. His welds look like
none I've seen: there's no bead to speak of,
it looks like the puddle has completely flowed out, like the the melted wire
was a slurry or something. No leaks,
ever. Anyone know how that's accomplished? I asked him how he did it, but he
didn't really seem to know--it's just how
he did it. I can only guess that he really cranks up the current but somehow
never burns through. He has a big Miller
MIG unit.
