[TheForge] cast iron welding

Fri Mar 19 12:51:00 2004

     Ralph, I just asked for cast iron rod, (my understanding is it must 
be used with cast iron flux) from what  I remember it was just rods of 
cast iron, square not round. My old welding  instructor (whom I keep in 
touch with) just repaired an old Parker vise for a friend of mine. 
Preheat, TIG, using Inconel rod.
