If all else fails with adjusting your helmet to work with your the arc, you can adjust your arc to work with your helmet by adding in a little pulsing into the DC arc. It's a bit of a kludgey workaround, but I find just a little bit of pulsing makes all the difference with getting my helmet (a harbor freight unit) to reliably trigger when TIG welding DC.
My helmet's two sensitivity settings ("low" and "high") aren't sensitive enough to reliably trigger from a pulsation-free low amp DC arc. Eventually I'll buy a better one that is more sensitive, but for now that's my "workaround."
