Can someone tell me what the difference ( or is there  1) is between low hydrogen 7018 and say a Hobart H 7018 electrode?

The varying suffixes (H, H4, H8 etc) are Hydrogen Designators

Different codes require different diffusable hydrogen levels in the weld deposit.

Here is a good article describing the picture for you

Don't use -H4 for the "bubble" demonstration;-)

Cool, I thought that since the H was a prefix that it stood for Hobart, I don't  or haven't used thier consumables so I'd never have thought of making the  prefix a suffix. :)
