That's it. I'm jus getting old. As read that post I remembered that I have one of those in my "welding" odds/ends drawer down stairs. I only tig, but I got a box of odds and ends at a garage sale a few years ago and since that one only applied to mig I just forgot about it!! You're right. Folds up like a feeler gauge set and has lots wire sizes nicely corrugated for cleaning. Thank you for reminding me.
