Reply:thanks guys.  whats the deal with 2% Ceriated(SP?)
Reply:So far, 1.5% or 2%La.  But I see a very close performance/resemblence with Diamond Ground's TriMix tungsten, as well as HTP's Quad-Mix tungsten.  All are very good so far, but I have yet to push them with high current. 1st on WeldingWeb to have a scrolling sig!

Reply:USA Weld has some good deals on tungsten, so Ive seen. The filler is a little more spendy if you buy from them.
