Oh Oh, I just checked it with water. I did pour about a pint of acetone in it to clean it out and kind of swilled it around to see if it leaked out anywhere but I doubt that's enough to really test it. I just finished sealing it with an epoxy gas tank sealer from Caswell Plating so hopefully it seals anything up that I could have missed!!!

I figured 10 or 11 was good for Tig, it is an auto darkening helmet but not a great one. I started to wonder cause I woke up with a bit of a headache, probably fumes.

Thanks,
Sean.
