I'm searching for a welding helmet with the grinding shield, but I would like to know if the grinding shield is scratch resistant and does the 3M or Cyber Weld Company replace parts free or at a reduced cost if it gets damaged from use.
Also can you wear the 9100 FX with a hard hat or does it need an adapter, and if so does it come with it?
Last can I wear a P100 3M respirator inside the 9100 FX welding helmet?
