Performance:
I'll give Florida Gas a phone call. Thanks for the lead. I tried Googling for suppliers, but most of the referenced web pages are either under construction or just a business card stating they exist. That included Florida Gas, I might add. I was hoping for an internet store front like Amazon or Cyberweld where I could peruse their inventory, but no such luck.

I'm reading the TIG section of the Welding: Principles and Applications book and it's terrific. Once I got into it I figured I'd check on the MIG section to see if I could learn something and it wasn't long before I knew I had to read that whole section too. I'll order a copy of the book for my next Amazon order. I tried using Amazon's search criteria to find a good TIG book but came up short. I never considered a book not specific to TIG, but that was clearly a mistake.
