Thanks. I use flux core wire all the time for carbon steel. Differnt
brands react differently, with Lincoln working the best and FireWire
a close second.
This is SS flux core. It looks like the surface tension is way to
high, tonight I'll try cleaning the work better, and pre-heating with
the oxy-propane torch. I had it on the highest heat setting of my
little wire feed welder, but my best working theory is that it wasn't
hot enough.
Sorry, no picture. Yahoo snipped it. I'll stick one in photos.
If worst comes to worst, I'll have a friend stick weld the stuff.
Would like to weld it myself, though.

welded some stainless for the boat tonight with the SS flux core wire. beaded up real bad, (see picture), didn't appear to mix in with the base metal. Any thoughts?
Held ok when boring the hole out on the lathe, though.
