[ RadSafe ] Which welding rods are hot?

[Ted de Castro]

I know I've encountered some considerably hot welding rods - but didn't 
notice the type designation.

I just checked my own supply - so 60's, 70's and 78's - I was SURE at 
least my 6010 would be hot --- but NO - they none were.

So - asked of anyone who has some hot ones --- what type?

thanks
