I am sorting through my pile of TIG rod, saving small quantities of the rods that I need and I will list the rest on ebay. This is like a little museum of TIG rod, ER70*, 308, 316, silicon bronze, all sorts of aluminum etc. I have a box of welding rod that says, written in permanent marker "TYPE 69". It is copper clad steel rod of some kind.
Any idea what this might be, maybe something oil hardening or air hardening?i
