I just ordered this --- I personally LOVE my Optrel -- but sometimes friends are over and want to watch so I grabbed this for them to wear. It has a range starting at 5... Lots of my TIG is done at 8
I keep two separate helmets for MIG... one for me one for buddies... they get the crap version! HA! I just don't like to have to re-do all the settings when I'm working - so hang them on the appropriate machine.
