Thanks for the link Tom. As Greg implied, that wasn't what I expected from a "Welding" site. In the time since I started this thread, we stepped up to a TIG machine. I gotta say, I may never have looked at this route if we had a TIG sooner. I did use some of the silicon bronze wire in the MIG and have to say, the results were much the same as in the link. I do think it has it's place. i want to play with the TIG and Silicon Bronze filler. I think that will have some definite benefits. We will see. I just have very little time for messing around right now.
