I bought a Hobart with the Grinding feature after my HF helmet stopped working after a couple of years. One issue is the grind feature is activated by turning an external knob on the helmet that also controls the amount of darkening. So you really need to take the helmet off to dial in the exact number you want. I got lazy and just give the knob a twist while it still on my head, so I don‘t know exactly where I’m at but it seems to work.

Another issue is I’ll forget that it’s still on the grind feature so I’ll flash myself.
